Timney Trigger Install

[RedNeck Jim]

I decided to go ahead & order a 3# Timney drop in trigger for my 15-22. I already have a CMC drop in for my AR, so I wanted a similar trigger pull for this gun.

I have searched here & read many threads but would like some input to verify I understand the peculiarities associated with the 15-22. Seems to be two factors that make the install on a 15-22 different than a regular AR. First, seems the 15-22 receiver is just a little wider than a standard AR. Also, the polymer receiver on a 15-22 can be damaged when the set screws used by the Timney are engaged.

From what I read, oversized anti-walk trigger & hammer pins are suggested. Seems to be two types available... JP & KNS. I have the JP, as the KNS are also non rotating, which from what I read is not necessary for this install.

Where I am confused is with the set screws which are designed to tighten down against the bottom of the receiver. I understand doing so can damage the polymer, so what should I do? I have read where some folks add a metal shim, to protect the receiver. I have also read that some don't tighten as tight as recommended... maybe just let them make contact but don't exert pressure. Also have read that some don't use them at all.

So if you use the oversize pins, does that relieve you of the need to use the set screws?

If you order from Timney they will provide you with the shim to go under the trigger for free if you ask, so it doesn't damage your receiver...

Already ordered from Natchez.

Since I didn't get an answer here, I sent an email to Timney. Jeff Dodge, the general manager replied within a few minutes & explained that all 4 set screws need to be tightened down, even when using the JP pins. He has already mailed the metal plate needed for the 15-22 & refused my offer of payment.

I have read lots of good about the Timney product but it sure is refreshing to see such great customer service to go along with a great product.

That plate timney sent was too thick. I had a friend make me one. You can probly sand it down. Let me know how it works for you.

Will do. .

I have the Kns pins and they work but after a lil while of shooting the trigger can flop around a little, it's not going anywhere because of the pins but the shim is nice to keep it tight with no movement.

Really, with the shim installed and the trigger tightened down you should have no need for anti walk pins.
The tension from the set screws will hold everything in place.

So are you saying you initially just used the pins without the screws/shim? I noticed a video where someone did that and thus why I asked my questions.

 

[AJB1228]

I never tried it with the shim and stock pins. When I bought the trigger 7 months ago I bought the Kns pins at same time. When I bought the trigger there was no shim that I knew about, called Timney about 2 months ago and they sent it to me. I just know for me at least with the Timney and KNS pins it worked but you could wiggle the trigger side to side a bit after shooting a couple mags with slide fire stock.

That makes sense but I had seen where some folks still added the anti-walk pins, maybe for some extra insurance. The JP pins don't cost much so since I already have them, I'm sure I'll use them. Thought I read somewhere that the Timney pins were a little short for the 15-22.

 

[AJB1228]

Just KNS pins but then I noticed it was a little loose but it still worked

 

[AJB1228]

I didn't install the shim my friend made yet but it seems the best setup is the anti walk pins, and shim so u can tighten the screws and set screws

 

[RedNeck Jim]

Just received the shim that Timney sent me for free. I was expecting just some junk pieces of metal, not a blackened, milled piece. Natchez has shipped the trigger too, so I am a happy camper.

We had exactly the same issue. With the shim installed, the trigger & hammer pin would not go in. Made no difference which pins we used, the extra depth of the shim caused the holes to not line up exactly. If someone tried to force them, I'm sure they would damage the sides of the receiver.

So for now, we simply tightened the set screws until they made contact with the bottom of the receiver, but did not put hardly any pressure on them. I'm thinking that, along with having the JP anti-walk pins, the trigger should stay nice & snug. It is right now. If for some reason I feel some slop later, I will look into adding a thinner shim.

Just got Mine Today

May try and install it today... see how it Fits... hope it is not to thick, if so i have some sheet metal that should work...



ok Just Installed It.... Fits like a GLOVE... ok maybe a 1 size too small glove

It needed a Little work ta get KNS Pins In... had lower (one that is caped by anti-walk) and couldnt get other one in, so did Main one 1st, then 2nd One... worked well.. kind had ta line up the holes with a small Punch... but only took a minute or so...


So maybe try a bit more with the shim.... Give it a little love and she should work...

I had a thinner shim made. That's awesome u got it to fit. I was a lil worried if I did get it in that it was so tight the holes on polymer would wear after awhile.

We tried all kinds of ways... even like you said. We could get one in but you could easily see the other would not line up. Sure we could have probably forced it in, but I'm not willing to try that with a polymer receiver.

Seems to me, the only reason those screws are there is to keep the trigger/hammer pins from coming out. The pins on the factory FCG are held in place by spring pressure, which doesn't happen on a drop in trigger assembly like this. My thought is, the anti-walk pins should do this all by themselves. I have a similar CMC drop in trigger on my AR & it doesn't use any screws. It uses clips on the end of the trigger/hammer pins... in essence another type of anti-walk pin.

The 15-22 dosent really have a lot of Action, in my opinion, to really Move the Pins so much as to Damage the reciever....

Mine are realy not any tighter Than stock... Just Lining them up took a Bit more work...

Now My reciever is also Dimpled.. since i dint hav the shim at 1st and tried to Drive the SCREWS to China.... but dont think that helped me any....

Either way....... love my Timney triger........

Just curious ...

Other than the drop-in convenience, why do folks pick the Timney, especially with the problems anchoring it in the 15-22? It seems to me that the FCGs on the AR pattern are a better choice.
