Can someone point me in the right direction for the correct KNS anti-walk pins for a 15-22? I plan on doing a trigger upgrade soon and was told I would need these. I know ours take 1.54 but according to a review on the midway sight there is a specific set for the 15-22?

According to the review this is NOT the correct pins..

KNS Hammer Trigger Pin 2nd Generation 2nd Modification Non Rotating

This appears to be the correct ones but out of stock on their site... anyone know of them in stock somewhere else?

Magento Commerce

Have u tried kns website directly? I saw them in stock the other day.

Isn't the site I listed above their site? Says out of stock.

I believe your link takes you to midwayusa. Here is a link to an in stock option.

If you want the other model, they have them in other colors so u can check to see if available.

This is what I used with my trigger kit.

Small Anti-Walk Pins : AR-15 ANTI-WALK PINS | Brownells

Ok so there are two different descriptions.. Not sure why? They look different also..

M&P15-22 Non-Rotate Trigger/Hammer Pins (GEN 2 MOD 2) Black

and

M&P15-22 Non-Rotate Trigger/Hammer Pins (GEN 2) Black

What is the difference? Does it matter?


EDIT... Found the answer..


There is no strength difference between the Gen 2 and Gen 2 Mod 2 sideplates. The only difference is cosmetic.

I like the looks of the Mod2 better lol.. now im just getting picky

Found the mod2 on joe bob outfitters.. hopefully they are in stock.. the site did not specify.

Question time...

If my 15-22 is having no problems, and I don't plan on changing out the fire control group, is there any real benefit to getting these?

None at all!

No reason to at all. I will say they do kinda look cool when installed but if I had not planned on getting a new drop in trigger setup that says to use these I would not have bothered.

Reading some of the other post, they do have a tendency to walk out. It's always to be safe than sorry.

Wow, had no idea they had that problem. Guess its a good thing I am getting them then!

I have about 6700 rounds down range since last Christmas with only one problem. And that was that my bolt needed a blast of compressed air. I may get the pin kit to keep on hand just in case something happens later.

Yeah, I guess it couldn't hurt... I am just looking forward to my new trigger.. Cant decide on the CMC or Timney...

What the KNS kit is really designed to do it eliminate the pins wearing away the hole and making it larger. This is an issue even the military knows about with regular ARs and alloy receivers. Just using some of the other type pins with the E-clips on the end is not going to help that out. Those type are O PK for eliminating the pins "walking" but not the wear. Just remember to buy the AR15-22 specific versions because the regular AR versions won't work due to the thicker receiver of the S&W. I use the Gen 2 Mod 2 type on both my ARs and AR15-22s

I put a set of GenII Mod II's (black) on my rifle, but pulled them when I dropped in a Geissele SD3G trigger. Bill Geissele speaks unfavorably of any pins other than the ones supplied with his triggers, so they sit in a box with lots of other goodies that,at one point or another, I just HAD to have on my rifle. If I ever have a problem with my trigger pins wallking or wearing, I'll post it on this forum.

You don't need them until you do . The J spring on my hammer broke allowing the pin to walk out. I put the KNS pins in, no more walking pin.
