Had thousands of M16A1 and M16A2 rifles in the arms rooms under my command over the years. The M16A1 rifles had seen Vietnam's jungle paradise. NEVER had any problem with fire control group pins walking out, and those had THREE pins for the select fire control groups. NEVER had any problem with the pins wallowing out the receiver holes. NEVER had any pins break. A properly designed and installed 2-piece civilian semi-auto fire control group with the correct pins does not need anti-rotation or anti-walk pins. The springs will hold the pins in place.

[@kauboy9816]

If you're using cassette triggers that already have bushings, anti-walk pins are needed, but anti-rotation pins give no additional benefit over anti-walk. The pin passes through the bushing. The springs never interact with them, but only the bushings.

[@Minutes-Mils]

Not a complete necessity, but definitely doesn't hurt anything.

[@C_oprator89]

Yea but anti walk take up the slop with most receivers. Christ everyone and their mama has had trigger pins walk out. People taking it to the polar ends is always dumb but KNS are well worth it

[@zeck8541]

Anyone who tells you they never saw pins walk or pin holes get wallowed out…good for them. They are lucky. I was an armorer and literally had to take lowers out of service because of this problem. KNS pins were the only thing that allowed the receivers to be returned to service. Does it happen often? No. Does it happen? Yes. Can it happen to your rifle? Yes. Is a set of pins cheaper than a new lower? Yes. Prove me wrong.

[@Techcensorshipbot]

I have a SSA trigger in my LR308 polymer lower with anti rotation pins. The pins started eating into the polymer. In that case it really did help out from keeping the pins from waking out and giving the trigger group more strength.

Thanks for clearing up this topic. I have always used standard pins with the Geissele triggers in my ARs but there are always those nagging voices for anti-walk/anti/rotation pins that I hear which makes one wonder. I have never any problems with the standard pins, but knowing is better than hoping. I did install an Elftmann trigger in one AR and it was obvious the regular pins wouldn’t hold it in well. I took Elftmann’s advice and bought the anti-walk pin set they sold and cured the problem. Therefore, your advice on this type of trigger made complete sense, backed up from my experience. Once again - Excellent video!

[@robertelliott5532]

Rifles built on 80% receivers have no hard anodizing in the pin holes to prevent excessive wear. The anti-rotation pin kits keep the trigger and hammer axii in the correct relationship to each other.

Take care in drilling the pin holes as they use the smallest bit… a drill chip can get caught and egg out a hole possibly causing a mil spec trigger to not function properly. … ask me how I know

[@ErikS308]

Another couple of reasons to use fixed pins. 1. you have an extremely valuable full auto lower and saving the lower forever is important so you you have to prevent pin hole wear. 2. you have an 80% where the pin holes are not anodized therefore they aluminum will wear more quickly from the pins constantly turning. I cut my own lowers and use .155 KNS pins in with my G triggers. G doesn't suggest it but it makes sense in my case.

After less than a mag it would be a few MMs out one side (right). I would tap back in and check to make sure the spring was set in good spot to secure it. After less than a mag the cycle repeated. So after not liking this I replace that pin with another and it continued. It always walked to the right. I assumed that whole was just out of spec.
