I have a Colt 6721 (LE Tac Carbine A3). I bought it new in 96 as an LEO private party purchase and thankfully the Billary Ban went away so I kept it upon retirement.

It has the screw type from takedown pin (which I destroyed by over-torquing the screw) and so I put a DPMS ball-pin in it. I am not satisfied with that product, it seems to easy to release.

Is there a better product, or a way to retro it to the standard mil style pushpins?
