KNS anti rotation pins

I think bravo company USA carries them, and maybe larue tactical or rainier arms as well.

It may be the pin, I hope it's not the reciever, but a in spec receiver with spec pins shouldn't have this problem.

If you're going to spend the money, go KNS - they're anti-walk and anti-rotation.

And they give you the operator tacticool mall-ninja look. :p

Are they worth the price? Does it actually prevent that much wear?

I think the wear argument is weak, but if you have a problem with pins drifting and you have verified that the springs are installed correctly and it still happens (should not generally), then you might need them so that your pins don't back out.

The M16/AR15 lowerwas designed to be replaceable, so the wear on the hammer pin holes was not considered a problem in the design.

However, if you happen to have a registered transferable full auto lower, you would be a FOOL not to have anti-rotational pins installed. KNS designed their pins for FA guns, but a lot of people liked the look and put them on semi-autos. There are a few instances where they make sense on semi rifles, but usually they are just there for the look.

gsxr600booya, it sounds like you need the anti-walk feature of the pins. KNS pins (http://www.knsprecisioninc.com/Gun%20Parts.htm) are awesome, or for $10 you can get the JP anti-walk pins (http://www.jprifles.com/1.4.8.1.php) which are also excellent.

Huh? Over 20 years in the Army, over 30 years messing with AR's/M16's, and this is the first time anyone has ever avowed that Stoner planned the obsolescence of the lower.

Being that the lower is the only serialed part, I cannot fathom that it was purposely designed to fail, and the US Military accepted that.

thanks i ended up ordering the kns. i have a cmmg lower parts kit and the trigger pin only started walking out the last 2 times i went shooting. i think the hammer spring might be a little light but i havent had an issue with light primer strikes so i just decided to get the anti rotation pins before it ends up doing something to my lower
