BCG

I have a franken gun and was wondering if there is a way to tell what kind of BCG i have?

Post pictures, or do your best to describe any markings on the carrier and bolt and we can go from there.

It has a T on the carrier and a D on the bolt.

D marked bolt is DPMS

thank you

The bolt is more than likely a DPMS. Is it a rough marked D or is it a fine D?

The T on the carrier may be Thompson Contender. Although they are usually marked TC.

Its a rough marked D.

It’s a DPMS.

thank you

I’ve guess I’ve never looked in detail at the various D’s I come across, but what would one with a clean D be?

I have no idea. I just wanted to make sure that it was in fact one of the rough type D’s as opposed to something else.
