- Sweet if you need them
This is a great addition to any upgrader's kit. If you're like me, you're always in your M4/M16 tinkering, upgrading or fixing it.
These babies are freaking steel man, the Rolls Royce of metals, and with your old pins, they are hard as hell to push out and put back in at first, then after you have been in your gun a couple of times, they just slide out if you hold your gun sideways, problem solved with these screw in caps.
If you need new pins, or don't trust your old ones, buy these.
