Best option besides aeros set screw - KNS Precision Bolt Catch Retaining Pin for the AR15/M16 w/3 C-Clip Retainers

I like KNS parts. Always seem to be well machined and finished in Nitride. I have their BCG Pin, Gen 2 & JJ anti-walk pins, take down detents, safety detent, bolt release plunger & this bolt catch pin. All have held up and functioning exactly as advertised and their small parts seem to hold up better then most. I had no problems installing this pin or the C-clip. I thought the C-clip would've been a little bit harder to install, but i used some hemostats that locked and it was quite easy and quick. I believe they gave me 3 extra c-clips just in case the clip falls off. I have somewhere around 700rnds on this clip and its still there even after being wiped down and cleaned. Yea the clip could snag or catch on something out in the field but for home defense or bench shooting shouldn't be a problem. Beats having to pound out another pin and mar the lower receiver.
