View Full Version : Adapter front pivot pin for older Colt upper

02-27-2012, 21:42
I have an older A2 Colt CAR 16" upper receiver group with a lightweight profile barrel. It has the larger hole for the perm/ screwable front pivots pins. The lowers I have are drilled for the smaller mil-spec pin.

My question is whether there's an adaptor out there that will allow me to mate this my lower to this upper? Like a sleeve that would go inside the upper and fit snuggly around the front pivot pin it would allow to pass through.

Does anyone else have experience with this issue?

Take a look at Brownell's they have pivot pin adapter, can't remember who makes it thou.

Thanks, think I found it here ( DPMS, but only 3.19 and should be exactly what I'm looking for.
