Two new builds starting soon

[Rivers3Plinker]

Hey all,
I'm putting together a custom 2289 / 1322 based pumper for my brother. He just bought a new house and had to mention to me he might be needing one of my fancy guns as he calls them. He was renting in a crowded neighborhood before and had no use for an air gun.

For anyone considering this project, I found the 1322KTE kit from AGD includes the shoulder skeleton stock, some pellets, a pellet pouch, and a set of safety glasses. With the exception of the glasses, this is all good stuff and even then I can use those too. It's a good deal and just as good a starting point as the now defunct DBO 2289 kit ever was.
http://www.airgundepot.com/crosman-1322-air-pistol-black.html

Plan is a relatively mild power upgrade with low maintenance compared to FT o-ring setup. Most of us have seen this many times before :

• 2260-003 24" barrel cut down to 20" recrowned and 2289 pivot + barrel band
• 2289 Backpacker pump arm
• Steel Breech
• Discovery bolt and handle
• Stuffed piston
• Angle ported valve with softer internal spring
• Mild exhaust port work and barrel port, lead-in polishing clean up
• Factory TP seal
• Polished trigger contact points and hammer weight

Sticking with the stock piston and umbrella seal because I know my brother and he won't properly maintain and oil a FT piston and valve setup. He'll neglect it as it is and just shoot it when needed. He doesn't need the added power and wouldn't pump it past 12 or so anyway.

I'm on the fence for optics and might let him choose something but tentatively I'm thinking the UTG SCP-U432AOD scope. It's an AO 4x32 with mildot reticle. It's affordable, high quality and seems like a perfect application. Better than my CP 3-9x32 with illumination I never use and 100yd parallax setting by far.
Anyone have experience with one?

Second project is a Crosman Vigilante pistol. I bought a Vigilante barrel housing assembly and a 2100 barrel from Crosman. I want to drill out the housing, cut the 2100 barrel to 12 inches and install it. I'll retain it with a set screw and fab some sort of shroud for the longer barrel end. I'm hoping for better accuracy and more power at the same time and if it doesn't work out I can swap the 6" OEM assembly back on the gun ( one screw ).

Pics on the way although I may post the Vigilante progress on the Dark Side instead of here.

Happy shootin!

I might be mistaken but, I think the 2289 pump arm has been discontinued. You can probly find them someplace other than Crosman but my guess is you'll pay.

Last I saw, davio at alchemy still has the 2289 pump arms.

Huh....I gave Crosman customer support part number  1389-025 Assy Forearm Black, and heard no qualms or reports of out of stock from the rep. Can't remember which reps I spoke with, but it was one of the guys. I was actually surprised not to hear ANY of the stuff I ordered was out of stock. In the past there has usually been at least a couple things out of stock.

The new 13xx series pump handle looks comfortable, and I'm pretty sure you can buy them off crosman. https://www.pyramydair.com/product/crosman-p1322-with-shoulder-stock-black?m=3608

You might be right about the 1389 pump arm, I didn't ask for one of those. I asked for the 2289 and they told me it had been discontinued. At that point I went to other sources. (ebay I think). I never gave the 1389 a thought.

I'm fairly certain I was given that part number by one of the reps the last time I ordered when they told me the 2289 part was out of stock. I just assumed it was a new part number.

I did consider the new 13xx pump arm too. Actually if my 1322 kit shows up with the new arm on it, I might leave it.

Starting a new post about the Vigilante and accuracy problems with the 6" barrel I'm having.

[avator]

I bought a Vigilante from the local pawn shop for $10 awhile back. It leaked the C02 as soon as you put it in. Maybe 3 shots. I ordered the kit for $15 and installed the entire kit. It workrd great. I was pretty surprised at the accuracy. My BIL developed cancer and the treatment had him so weak that he couldn't cock his Vantage NP. I felt bad when they came to visit and he had to sit and watch us shoot. I ended up giving him the Vigilante and a pair of Daisy Red Ryders we had picked up. He's not keeping up on his squirrel population but, he's shooting and smiling again. I just built my sister (his wife) a 2240 carbine. They will be in town in a week or so for a visit and to pick it up. I'm sure he will enjoy that... the squirrels, not so much.

Cool....great garage sale score. I need to start looking for those. I see craiglist adds on occasion.
Hey what is the kit you bought for $15? and is it from Crosman?
I debated a 2240 seriously. I might do one for myself instead now that I have an HPA gun and a CO2 pistol. I was also thinking of the HiPAc the total $$ costs always deter me. I know there are other fun projects for less money like a steroid 392 perhaps.

I'll have to look it up when I get home, they got some sort of a block here at work.

OK so the pumper arm showed up last week and it's a 2289 pump arm for sure. Anybody needing that part use the part number I posted. FWIW the 1322 showed up with the new style grips which is cool, but I still don't like it nearly as much as the 2289 arm. Not even close. It's better design than the old arm, but still too small for me and not what I want for building a carbine. One important note is the new style pump arms on the 1322 are screwed into the linkage arm not pinned. Not sure yet how I will counter bore the plastic 2289 arm to use the screws but I will figure out something. Hopefully I won't trash the pump arm!

Also that 1322 kit deal from AGD is pretty good for the money. One could actually just put a longer barrel in the 1322 by drilling out the barrel band and use it as-is. Stock breach, pump arm, and sights with the skeleton stock.

The Vigilante project is a bit of a bust. I cut the 2100 barrel and tried to chamfer the lead-in like Crosman but they used a long taper cutter of some sort. I came close but not the same. The gun did not gain any noticeable power and feels weaker! Completely subjective based upon time to target and noise at impact of a metal can but not impressed. This is with a 12 inch barrel. Plus it looks silly with this long pencil barrel sticking out. If I can figure out the issue it might be worth the effort to fabricate a shroud but for now, I put the stock barrel and assembly back on it and I'm just going to enjoy plinking with it.

Looking for that seal kit, here is one for $20 and free shipping.
http://www.ebay.com/sch/sis.html?_nkw=CROSMAN%20357%20Seal%20Kit&_itemId=130762850753
The more I think about it the more I think I ordered all the parts from Crosman. I'll keep looking.
Here's another for about the same price.

[gillchaser]

My 1322 came with the new style pump arm and I'm agree , it's still not comfortable to me . Too skinny . I'll be ordering a 2289 or whatever is available.
Look forward to hearing how you install yours . Kirby

Thanks - yeah if you know what you need, direct from Crosman is always less than Ebay or Amazon or anyplace else for that matter but that only makes sense. Crosman parts is great and they have very helpful reps too.
Thanks for taking the time to dig it up.

If you want, I have a couple old style pump arms. I'll trade you one for the new style. That way, you can swap the 1389 grip, without drilling it.

Thanks for the offer!
However I plan to strip the pump linkage off one of my MK-177 which is a total POS at this point and has the same assembly as the 13xx guns. All Crosman did on the new 13xx arm was tap the holes for 6-32 and put long screws in there anyway. The MK177 has been worked over by me and the bolt is worn etc. It's junk now and has wandering POI. I have another that is box stock I will keep for plinking and fun.

Latest update - I have cut the barrel down to 18" and re-crowned it. Oddly the OEM crown on the end of the 24" barrel is basically non-existent. I should take a pic and post it. There is no crown cut and it's completely flat. Perhaps they've started a new machining process or something but it looks weird.

I've also done the trigger with the usual mods, lighter spring, polished surfaces, and washers. I found some perfect .0145 thick ones in my stash of tiny parts off office machines from work. I also polished the hammer weight.

I ordered FT piston and valve from AC Customs today as well as a 4x32 AO UTG air gun scope off Amazon and got a great deal on that. Comes with dovetail rings.

I could use some opinions on a brake. I'm on the fence since I don't believe my bro will happy or willing to use a moderating brake.
Here's what I'm looking at:

• HPAsports 32 port short brake for $38 shipped
• Crosman 1701P brake, Disco brake or similar. These are around $20 not including shipping
• Custom shroud from AC Customs with no moderation. Price depends on length but probably $45

Most of the brakes I see on Ebay are ugly junk or overpriced, repainted Crosman parts.
Personally I like my custom shroud / brake from AC Customs but it looks a little suspect like a huge sniper log hanging off the end of the gun.
My bro works for state gov and he can't risk the hassle of anything suspicious.
If anyone has other sources for cool brakes please let me know.

Also does anyone know the dims for the roll pins for the 13xx pump arms? I bought some 1/8" x 1" today as well as 3/32" x .75" and I'm going to see how they work. I think the 1/8" dia are the right ones.

Next I'll be working the pump arm slot, deburring it and drilling out the pump arm pin hole to 3/16" and deburring that too.
I plan to leave the valve from AC and transfer port alone except I will replace the spring with a softer stainless one. I think the TP stock size is OK and I won't gain that much FPS by going larger unless others here disagree.

Thoughts?
 
 

[Rivers3Plinker]

Roll pins for the 2289 pump arm are 1/8" for sure.

[Rivers3Plinker]

Ok so the NEW 1322 pump arm has tapped holes for the screws used on the new 1322 pump arms. However they are drilled and tapped for #6 screws and if you want to put a 2289 pump arm on it, all you have to do is drill them out to .125 and press in the roll pins through the arm just as you would with the old 13xx arm. Works just fine but you're not going back easily.

Additionally, the MK177 pump arm linking while identical to the 13xx has one of the holes ovaled for ease of assembly with the MK177 pump arm which screws together with three screws and uses solid, center-splined pins in the holes in the pump arm linkage. This won't work with a 2289 pump arm and 1/8" ( .125 ) roll pins.

AC Customs valve and piston arriving today. I should have this assembled by the weekend and start getting some groups with it.

[Rivers3Plinker]

Check this out. This is the Crosman factory "crown" on the 2260-003 barrel I just received. It basically doesn't have one. Might be hard to see in the pics but the rifling just stops at the muzzle face and that's it.
I don't really care because I cut it off and did my own but I was a bit surprised anyway. The barrel turned out well and shoots great groups.


And after I crowned it myself using drill, sandpaper, brass screw technique with compound and then treated with Vans cold blue.
Note it's a bit dirty because I just had it against the wood on my bench a second but you get the idea.

[Rivers3Plinker]

AC Customs shroud will be going on it next.
