Title: 13xx plastic breech sights and sight mods
Post by: stonykill on February 21, 2014, 11:43:07 AM
  I wanna see em and hear how anyone approached this. This morning I shot my 1377 rested and my Beeman P17 rested. I make 1 torn hole with the P17 rested. The 1377 I have such a hard time with the sights it is a quarter size group. I was shooting at 10 yards indoors.
   I am really not wanting to spend $100 on a steel breech and sights on a $60 gun unless I ABSOLUTELY have to. I know many enjoy spending $300 on the 13xx's. To me that does not make sense. Not my thing.

   The P17 has nice FO sites that the rear sight has nice adjustments on. Looking to either purchase or make something similar for the 13xx's. I am sure someone else has done this but a search does not help me.

   Pics anyone?

   FYI if I REALLY REALLY take my time aiming the 1377 or 22 I can get good groups. But the stock sights are just not working for me. I want something I can get on sight quick and squeeze without spending $200 to make 2 pistols hit their mark

You can get the scope mounts Crosman makes that go directly on the barrel, then buy whatever optics---100-150 bucks.  I know you said you didn't want to spend the money, but seems the only way to get real accuracy is to buy optics or better sights.  I use the peep sight on my 1322, seems to be more accurate.  Have you polished & lubed up the trigger components yet?  That makes a world of difference, too.

Joe

   yes I did the recommended trigger mods.

   I should have added I want to stick with open sights. I want to holster and carry these around the farm and on hunts as a backup weapon. I have to admit I'm really disappointed with these 13xx's in stock form. The sights are just horrible. Barrel's wiggle all over the place. That I can fix. Sights.... looking for ideas. And if push comes to shove to make these shooters equal to my $39 P17 in stock form I'll spend the $100 each to do it. Or make them carbines at that point. Just really disappointed in these weapons. My 2 are not living up to the hype.

Yeah Tom,

Seems like Crosman made them so you have to get the steel breech or a custom breech so you can use better open sights.  I am that guy who dumps all that money into it...lol.  I will be getting a left handed breech and a nice optic for mine.  I am a right handed shooter, but with an air pistol, I like to cock and load with the left.  Makes more sense to me.  I'm also ambidextrous.  I put a left handed breech on my carbine build and I love it.  I hope someone else will add to your thread on open sight options w/o breaking the bank.  I will be keeping an eye on this one.

   I put the Crosman rifle stock on my 1377. That makes the sights much worse, as your eye gets closer to the rear sight blade, which makes the gap between the rear sight blades way too wide. It also makes the peep hole on that sight way too big. I suppose someone could make a new rear sight from scratch. Or fill in the old rear blade and drill a different sized peep hole or cut new rear blades.

I may be wrong, often am, but I don't think sights alone are going to make the 1377 as accurate as the P17.
Seems that you have to stabilize the barrel & possibly recrown.   Also pellet placement by way of an extended probe can help.  Shimming the barrel band to prevent movement helps.  And as mentioned trigger/sear/spring work.
All of the above is already done in the P17 and it is a lighter pistol.  Limited to 400 fps and ment for target shooting.
I'm no expert & am often wrong but, I think you got to get deeper into the wallet to do what you want.

my P17 is bone stock from China. Has not had any of the above mods done to it. But bone stock it has a great trigger and really nice sights.

  I was just thinking that perhaps some of you don't understand my point. It is probably just me, but I can not get a quick repeatable sight window with the stock sights. Without sights I can use consistent I can not shoot consistent. So I'm wondering aloud if I should just as a test get intermounts  and an inexpensive red dot. If I get accuracy and repeatability I want than I decide to spend the bucks or fabricate up a rear site mod the front sight.

    This will be my default plan if no one has an decent sight in mind to mount on the stock plastic breech.

Me I just cut down the front sight a bit  and used a  7/16 screw eye with 1/8 eye hole (squeezed closed) to make a front peep to use with the

rear peep.

Very quick target acquisition , sight alignment and good overall visibility.

Not holster tough  but with some design effort could be there.

Center the target in front peep center front peep in rear peep very natural for me and more accurate at distance for me...

If using post and notch I like a V notch and thin post front sight; once again quick acquisition, finer targeting and overall visibility for me.

 a little imagination and work it is easily doable...

also  these can really benefit from some barrel tuning  just getting rid of a burr at the transfer port on my PC77 took it from  large shogun

groups at 20-25 yards to  3/4" groups (side rested).

many of the barrels also need some leade work I do it my way with wet dry...

These are great guns but come on be willing to do a bit of work they are 50-60 dollar guns...

Post by: stonykill on February 22, 2014, 03:18:10 PM
  shot about 70 pellets through the 1322 today. Last night I sanded the top of the rear sight to be flush with the top of the adjustable portion of the sight. I heated up the front sight with a heat gun and straightened it out. It was leaning right. I sanded the sides smooth on the front sight to eliminate all of the casting flash and parting lines. I put a dot of bright red nail polish on the front sight. Now I can see through the sights pretty well.
   Outside while in between wind gusts at 10 yards, 20 shots makes a ragged hole the size of a quarter. It is just too breezy to shoot at longer distances today for grouping. But I was popping a soda can consistantly at around 20 yards.

   So I'm still looking for a sight upgrade but at least I have a starting point for the 1322. Some other day I'll do the same to the 1377.

Sell the 1377; easy fix. Yes, they are rough out of the box, and the stock sights are pretty poor. If you do not want to sink a couple of hundred bucks into the gun to improve it, get out now. Better to take the money you do not put into the 1377 and find an air pistol that better fits your needs. Peruse various AG classifieds for good deals on second hand pistols.

  if I can spend 1/2 hour of my time like I did on the 1322 to make it shoot good with the stock sights I'll have a good starting point. I have been researching mods and yeah, some guys dump $300 into it to get what they want. Other dump another $60 into it to get what they want. I'm the 2nd guy, not the 1st.

   I may just end up making a rear sight. Like this one http://www.network54.com/Forum/275684/thread/1192369060/1377+home+made+rear+sight (http://www.network54.com/Forum/275684/thread/1192369060/1377+home+made+rear+sight)

  did most of the same to the 1377 sights. Only difference is I did not have to bend the front site. At 8 yards indoors and rested, 5 shot groups I was getting nickel size groups which of course I am not happy with. BUT I can use the sights now. I'll play some with various pellets 1st but am guessing a recrown is in order.

   What I forgot to say about  testing the 1322 is I was not rested but not totally offhand either. I'm left handed, and rested my left shoulder against a tree. Offhand from there. But I was body side rested getting 20 shot quarter size groups outdoors in the breezy day at 10 yards. I know on a still air day I can improve on that.

   BUT I have the stock sights so I can use them.  :D

I look at the 13xx as a $100 gun.   This is because the Crosman steel breach is a necessity. Then spend some time and about $10 to $20 and you can have a good 17FPE gun (for the 1322/2289), so you end up with a $110 gun that is a lot better than the $150 to $200 MSPs and a lot easier to work on.

True.  though all you need is a low cost Daisy Red Dot (between $8.00 and $12.00 depending on where you get it).   And I do not count the optics as part of the price of the gun.

Besides you can buy a long enough screw and file the sight from the plastic breach to fit the steel breech thus costing nothing extra for sights.

And it is only $90 to $100 if you do not do any of the power mods.

  I do not count scopes as part of the cost on a rifle. But on a pistol I do count count a decent set of sights as part of the cost. Red dot is out of the question for me as a long term solution. I want to holster my pistols. If one of them becomes a carbine that is different entirely. But I want holsterable pistols to carry around my property as I work.
   And of course my original post is about not liking the stock sights and looking for an affordable alternative. So reusing the stock rear sight that I don't care for when using it as a pistol is out of the question for me.

    I have made my stock sights usable enough for now for me. IF I decide to go steel breech on either or both I'll just not so good it up and spend $45 to $60 for a decent rear sight

Same sights on my 2240.  I kept the plastic breech for economy's sake and made my own sights out of hardware store fare - square bar stock, angle iron, a brass hose fitting, and screws.  The front is the same way, with an empty CO2 capsule for the shade.  It shoots about as tight as my Marksman 2004 w/red dot (same as the P17 but older name).

  thanks for sharing that. If it shoots as good as your 2004 it shoots good. Providing your 04 shoots like my P17 does.

   This is the kind of stuff I'm looking for. Custom creations. That floats my boat.

Not sure I understand the mentality here, buy a $60 gun, and add maybe $200.00 so it sights in better?  Take the $260.00 and buy a better gun.  I looked at a couple of video reviews on your 1377, they were shooting well right of the box.  1/2" group at 10 yards?  Maybe you got a lemon, but too late to return it now.  Before I buy any air gun, I decide what I want to do with it, what discipline, then research like crazy and eventually purchase the best that I can, or want, to afford.  Make sure you get your "bang" for the buck, or should I say "phftt" for the buck.

   Ok , that is not at ALL what I said.

 As I said earlier in the thread SOME people will dump $300 into a 13xx. Some will invest an additional $60 to get what they want. I am the 2nd guy. Also wondering where I said dump $200 into 1 ONE gun. I did not. I said $200 for TWO guns was MORE than I wanted to spend on mods.
    AND my problem is with the stock sights. Most everyone agree's they stink. But if you read along you would have seen that I fixed that particular problem by spending 30 minutes working on each gun and spending ZERO dollars.

   For the record I'm NOT going to spend $260 on ANY air pistol... ever. New out of the box or in mods. I will carry one of these daily all spring and summer on my hip as I work the property at home. Not going to put a $260 air pistol through that kind of abuse.

 Put a Red field scope on mine with Crosman mounts. True the barrel moves, even though mine is version 1 with metal breech, but scope moves with barrel so does pellet. Scope (4x36) used was 10 bucks on eBay. Put a carbine stock on 1377, add a sling and carry it that way. 1377 is big enough to not be real comfortable in holster if you are under 7' tall.  ;)

  if you guys wanna talk $500 Ag pistols how about you start a new thread ?  ;)

    I want to see inexpensive and homemade sights on the thread I started. Not back and forth bickering about an AG I have no interest in at ALL.


   Thanks in advance  :D
I just want to point out that the 13xx guns are a steal for the price.   As the OP said that it is not worth sinking $100 into these guns, and made a crack about the higher cost guns.

 I am the OP.

OOPS my error.  Well some one had made that crack.  If I had realised not OP I would have said nothing about it.   My apology.

For the record my only interest was supporting these guns as something that can be very usable for under $110.

  I know your intentions were in the right place.


     Now back to our regularly scheduled programing... inexpensive or homemade sights  ;)

Aluminum breech - $36.00  Benjamin Discovery rear sight - $15.00  Chavka Barrelband w/sight $55.00
You really could use the OEM 13xx front sight.

One thing you might want to do is drill and tap your breech 8x32 put in a set screw one one bad thing about the plastic breech is the only thibg holding the breech end of the barrel is the transfer port some guys even put 2 set screws in if you do don`t over tighten it remember it`s only plastic but even a snug fit will keep the barrel from moving hope this helps

Hey .... my humble apologies regarding my post, you were correct, I did not "read" the original in detail, and totally misunderstood what you were trying to accomplish.  I totally went off on the wrong tangent, thinking someone was "putting lipstick on a pig" ... anyway.... again sorry.

The aluminum breech from  http://www.bryanandac.com/ (http://www.bryanandac.com/) has the cutout for the OEM style sight.

I should note, since that build I have broken in the gun and found its preferred pellet and groups are now even tigher!  The sight is unchanged.  If I had to do it all over again (which I will for my 1377 next) I would make the rear blade much shorter.

I had an old 1377 that I put a new plastic breech on and looked through my parts for a rear sight.  What I found was a Crosman rifle sight (B20-02-00) $6.70.
 
(http://i129.photobucket.com/albums/p212/wwk1a/100_05251.jpg)

This sight mounts with the rear breech screw.  Just screw it on.

(http://i129.photobucket.com/albums/p212/wwk1a/100_05261.jpg)

You may have to grind down the screw on the elevation adjuster to lower it enough. 
I also had to glue a fiber optic rod from a 760 sight to the 1377 front sight as I couldn't get the rifle sight low enough.
The rifle sight has a slightly larger U cut in it than does the OEM plastic breech sight.

(http://i129.photobucket.com/albums/p212/wwk1a/100_05291.jpg)

If you want a smaller U cut you will have to mount a Discovery rear sight(1761-026) $13.75.  You can do that by putting 2 #4screws through the plastic breech.  You have to dremel out the ridges inside the breech so the bolt clears the screw heads.  Then grind the Discovery sight base to size and drill to fit.  You would be using nuts to secure the sight.  Pictured is the Discovery mounted on a aluminum breech where breech could be tapped & threaded.

 just re read all of this. Thanks guys for all of the input. And keep the ideas coming. Threads like this can be helpful to so many.

  Bill, again, thanks. Next time I place a Crosman order getting one of the sights you mentioned

I too own both, 1377 and a P 17. Like you I've enjoyed shooting the P 17 more, still think the P 17 is best deal in any air gun. I also had to use a heat gun to straighten my 1377 front sight, little file work to thin and square the blade also file work to the rear sight. Beyond the normal trigger mods 13xx and 22xx pistols benefit greatly from a trigger shoe. Both my 1377 and the P 17 get a lot of use in the Winter months until Co2 friendly weather comes around.Both pistols are great examples of what a little bit of money and ingenuity can achieve.(http://i84.photobucket.com/albums/k36/cajuncj/air/1377C/IMG_7898_zps8339fe03.jpg) (http://s84.photobucket.com/user/cajuncj/media/air/1377C/IMG_7898_zps8339fe03.jpg.html)

 ok, here is what I did to the stock rear sight. I shaved a lot off of the top rear portion. Having the metal v notch even or lower than the plastic caused double images.

  I also made the adjusting slot in the blade longer to get it low enough. Nail polish shown here and on a dot on the front sight.

    (http://i169.photobucket.com/albums/u215/stonykill/DSCF3431-001_zpsbb199215.jpg)

   I also sanded the base of the rear sight to get it low enough. Didn't measure how much but I did it on a random orbit sander and it was enough removed that in order to get the rear sight to sit level I needed to shave the top of the rearmost round portion of the plastic breech. Sorry for the bad pic.

   Probably took an 1/8th of an inch off of it.

   (http://i169.photobucket.com/albums/u215/stonykill/DSCF3434-001_zpsd4e0664b.jpg)

   Now at random ranges to 20 yards I can shoot a hickory nut off of a tin can every time. And shot this group yesterday afternoon, just over 5 meters (17 feet exactly) offhand with my right shoulder on a door jam. I'm left handed. 5 shot group at 5 pumps. All in one place except for one which was 100% my fault.

  (http://i169.photobucket.com/albums/u215/stonykill/DSCF3422-001_zpsb1efbc2b.jpg)

   So until I place my next Crosman order and pick up the 2 Bill suggested, I'm pretty happy.

  Thanks to all with suggestions!

I really liked the Discovery rear sight and so replaced the larger rifle sight with the Discovery.  It has a narrower sight V and is smaller and IMO fits the gun better.
I used a #4 screw & nut to hold the shortened sight to the plastic breech.  I had to dremel the ridge in the center of the inside of the plastic breech to fit the nut in the breech.  This is done so that the bolt can move freely.  After the nut & sight were in place I ground down the nut to make more room for the bolt.  I drilled a small indentation in the top of the breech for the elevation screw to set in to further solidify the sight.

Oh ya,  The Discovery rear sight lines up with the standard 13xx front sight.  No modifications needed.

  nice Bill. You made up my mind, next order just that sight and not the other as well. Easier to mount too that way  ;)
