Trigger options

[jagen heie]

indeed and thanks for the info. it seems like a cheap upgrade.

I got the Hogue grip (very nice in my opinion) and the JP Springs along with a few other minor items from Midway. Shipping worked out to be minimal that way. I put the springs in and didn't do any polishing (yet) and am very happy with the difference.

Half Swiss, I received my springs today. The trigger spring legs are not symetrical. One leg is bent slightly out then bent parallel again. Do I just push trigger into the housing and ignore this?

Please link thread to beltfed's how to if any. Interested on this upgrade myself. Thanks.

ok I'm new at this. I want to know if you can replaced the whole trigger assembly in a 15/22 with a timney drop in or something compatible to it. I've gotten some info and it all seems to contradict itself .
Even had a guy that builds AR's tell me the MP15/22 wasn't a real AR and that it was a plastic gun so no I couldn't

Any help or good info would be greatly appreciated.

The "guy that builds AR's" apparently makes statements without doing his homework and has issues with polymer firearms. While the 15-22 differs some from it's 5.56x45 big brother, it's still an "AR" platform. You can't replace all the parts with mil-spec AR parts, but so can certainly drop in a generic AR fire control group (trigger, hammer, disconnector & associated springs)... many of the forum members have done just that.

thanks for the info. Think I'm gonna drop one in . Saw a timney for 129 at last gun show.

not symetrical is not an issue

Yes, I also noticed they were not symetrical. I just put them in (only one way they can go in) and the contour of the 15-22 "lower" keeps them in position.

Trigger Adjuster/Set Screw

OK - just finished putting in a JP 3.5# trigger kit with a little polishing and could not believe the difference. I did not think I could do something like this, but the posted instructions on the site and what comes with the springs made it seem easy. Much smoother and lighter; am now considering the set screw in the grip bolt hole to help with the take up on the pull (came highly recommended by friend and armorer). He was concerned, though, about the polymer lower frame and effect it might have on the replacement screw. Anyone have some experience? Brownell's currently has the screw "drop in trigger adjuster" available from J&L Research for about $44. Can't believe it would give me anymore than I got with the JP Springs and a little polish.

a 1/4" long 1/4-28 (best i remember) set screw is about .20 cents and will do the same thing... ive got about 12,000 rds in mine since the mod with no problems. I also know of 2 other people i have walked through the process with no problems... be ware of people who say a .20 cent part wont do what their $50 part will do when its the same thing...

15/22 Trigger 101

To get a smooth trigger on 15/22 for very little money ( if you dont feel "comfee" doing this than dont but here are some suggestions for those who are thinking about this mod)

1. order the j&p 3.5 trigger spring kit $10.00

2. remove the 2 pins in the second pic. the top one should be removed first( i shouldnt have to say this but hang on to the parts they are spring loaded)

3. once they r removed you can see how they interact in the 3rd pic (i didnt bend the hammer spring around because i didnt want to chase it.. and the disconect is removed so that there is no confution on what needs to be polished) these points are the ones that need to be polished

4. after cleaning up those surfaces reinstall new spings and then reinstall into lower... it really is that simple

5. is the optional set screw to remove pre travel in the trigger if you remove the grip screw it can be inserted in under it and pokes threw like in pic 4

hope this helps

and im sorry for the crappy pics i used my phone

I am one of the two people that Beltfed walked through this. If this old Carolina country boy can do it, anybody can. But I will say it has one bad side effect. Now that the trigger is so smooth & crisp, I really burn through some ammo now !!!

Nice price... I've seen 'em around for 175-ish. 129 makes it more palatable for a rimfire fun-gun.

If you've got pre-updated (non-blue) springs now, you might want to consider the JP 3.5 springs and a little bit of polishing (as described in this and several other threads). Ten bucks (plus a little shipping) and fifteen minutes is about all it takes and it really does make a huge improvement. Mine went from gritty & creepy to smooth and crisp. I'm intrigued by the set screw to take up some of the trigger travel, but I don't really have any complaints with the way it is now.

All in all, it's the best (and cheapest) mod I've seen for the 15-22 so far.

for the set screw do I drill and tap a hole? Have not taken the grip off yet so I don't know whats in their.

No. The set screw goes in the grip bolt hole. Install the set screw & then reinstall your grip. I did have to use a slightly shorter grip bolt to keep it from hitting the set screw.

 

[shooter1950]

You forgot to mention the two springs and pins when the grip comes off. Lucky I saw the first spring as the grip was coming off. I would have lost something, thats my usual luck. will try to get the set screw and shorter bolt Monday and give it a try.

 

[squeaky]

i want to try to lessen the pre travel. what size is the set screw? should i replace the pistol grip bolt? if so, what size(length, diameter)?

cheers

Its been awhile but I'm pretty sure its a 1/4-28 and 1/4 of inch long

 

[shooter1950]

Just take or measure the bolt and get one 1/4 in shorter and it will work fine.

 

[deadeyedick]

Here is the solution. Go to Junk Yard Genius.com AR-15/M-16 Pages, page 1. NOTE, substutate the 1/20 threaded 1/4" to a 1/28. S&W used a different thread than normal. I had about 1/8" of creep that was like dragging the sear over rough sandpaper. No I have no creep at all.

 

[Squirrels Worst Night]

I just ordered one from JPs website, Midway was on backorder so hopefully these arnt. It didnt really say. It was $18 with shipping. Its the one for the AR-15 and those will fit the 15-22 just fine right? I cleaned my FCS the other day(was really gritty) but this will help with pull alot. Maybe accuracy too. Thanks for the idea.

Anything else I will need to do to the assembly also? And the small spring, how does it come out? Do you just pull on it?
