13xx plastic breech sights and sight mods

[stonykill]

  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

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.

[DavidS]

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.

[DavidS]

OK Found who, My appology.

I feel bad about my error.  It was pappy that I should have been addressing.

[DavidS]

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 

[BillK]

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.

 thanks Bill. That looks like a good solid fix and keeps things affordable.

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/ has the cutout for the OEM style sight.

 thanks Xander. As soon as I get a chance I'll be making one similar to yours. Thanks for sharing

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.
 


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



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.



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.

thank you Bill! Great info you shared!

 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.
