[ARCHIVED THREAD] - Colt receiver?

Posted: 12/19/2008 7:25:56 PM EDT

This A1 receiver just came to me last week:

It's got at least partial proof marks that look like the right stuff:

And the barrel that came off it is marked "C MP C" appropriately enough.

But I hadn't seen machining quite like thise before:

Granted I haven't had my hands on many A1s, but I had to ask if this looks like Colt work. If not, what might it be?

I would say that's a Colt. But if you have any doubts, I could use it for a XM177E2 build!

BTW, does it have the recessed front lug?

Nope; I think that's visible in the top shot.

Top shot shows rt side of upper, the recess would be on the left.

Nope, the recessed lug (or counter bored) would be visible from the other side.

ETA: A little slow tonight.

I guess I should have said "counter bored".
