2015年4月11日 · If the KNS pins are still stainless, they will gall and develop rough burrs against hardened tool steel. Its just a matter of time. I heard they may have been redesigned. Not sure. The Geissele pins are a bit oversize, purposefully, and made from extremely hard steel precision machined to very exacting tolerances.

2023年2月22日 · Unless my lower is very tight of the get go, I run KNS machined oversized pins, (not the anti-rotation pins). They eliminate any little movement and noticeably tighten up the trigger. Posted: 2/23/2023 11:42:48 PM EDT

2019年2月16日 · A little bit of slack is normal. We might have one on the thick side of the tolerance, but if the bosses for the bolt catch are too wide apart (TDP spec gap is 0.167 + 0.010 / -0.00), the bolt catch's width is 0.150 +/- 0.003, a bolt catch would have to be out of spec thickness to compensate for that.

2019年6月4日 · The brain trust over at /r/AR15 recommended KNS anti-rotate pins. I ordered a pair (one for my Ruger, one for an upcoming build that I already have an Aero lower for) just in case. [ARCHIVED THREAD] - Anti rotation/ non rotate pins and their purpose.

2020年6月5日 · Put the KNS pins in and the first thing the came to mind was “this shit is complicated”. Fiddled with it to get the grooves in the pins lined up to get the dog bone thingy on, then put the allen screws on with locktite. If you have fat …

2012年4月24日 · The stupid in this thread is that people are saying that these KNS pins are needed to keep receiver pins from walking or to keep reciever holes from becoming "egged". Steve from ADCO, Bill Geissele, and other AR smiths gave their recommendations on this forum and others regarding KNS pins, FCG hole size, etc.

2009年7月2日 · The KNS pins also have sharp edges on their ends, which tend to tear up the J pin on the hammer upon insertion. Depending on your Gen of KNS pins, you will have at least one hollow style pin, which is weaker than any solid pin. Some Gens of KNS pins allow for a small amount of pin rotation which can lead to a poor trigger feel.

2017年2月2日 · IF you've ever installed KNS anti walk/rotate pins you'll know that they DO indeed move (but less so). ANY movement will cause egging eventually. Doesn't matter if you use standard or anti walk/rotation. Hell, vibration alone would cause enough friction to cause wear. The "KNS pins stop pin hole wear" is a myth and is false.

2012年8月8日 · Geissele SSA pins are 0.1550" dia 0.0001. Holes in the trigger can be 5 tenths over Geissele pin size. Kns pins are either .154 or .1555. So they are either too loose or just about a metal to metal fit in Geissele triggers Geissele pins are chrome-moly steel that is rough turned, rough ground, heat treated and then centerless finish ground.

2010年1月27日 · My 9mm pins were walking so I put the KNS pins in. My .22 conversion kit broke both the hammer and trigger pins, so it'll be getting KNS pins as well. Posted: 2/6/2010 8:54:11 AM EST
