Rock solid. - Elftmann Tactical Anti-Rotational, Anti-Walk Pins

I have an old Colt AR with a million rounds through it. The pins began walking this year. This product has totally put an end to that. My only beef is the blues steel fittings. Just kinda dated. I live in a crazy humid environment, and bluing is insufficient protection from rust. Would much rather see something more modern like a matte Cerakote finish. The whole industry needs to get away from bluing guns and gun parts. It’s old technology. A controlled rust process. It kinda sucks. Otherwise... 10/10 would recommend.
