Colt R6521?

[DanTSX]

G19. I'm pm'ing you some specific links with info.

I hope you enjoy the rifle, or are able to make a hell of a trade with it! A few years ago I'd be making you an offer lol. But with the change in laws, I'm going to look for a SP1 in coltguard.


Edit: memory just kicked in. Those should have the old school screw type front takedown pin. That does look like a replacement, but that looks like the original upper.

Not sure on sear block.

ScottRyan is the resident Colt ID specialist. Maybe a PM to alert him of this thread? But again, colt configurations vary greatly. Especially in small batches.

I just bought one of these NIB. Still has the bore wick. The front pivot pin on mine is identical to the OPs. I didn't know how rare (or at least uncommon) the R6521 was - actually didn't know it existed. Seller had it listed as a AR-15A2 Gov't Carbine (box is serial'd but states R6520), I just figured the receiver markings were typical Colt "change as we please".

Now I have a safe queen!

I like it... I know it has the odd pivot pins, but it is a gorgeous rifle... Congrats..
