I walked into my local shop to check out Leo trade in guns and spotted this pistol on the used rifle rack.
It appears to be a 11.5” colt upper on a psa pistol lower.
I really didn’t want the lower but the upper seemed like it was worth what they were asking alone in parts..
So, what have I got here?

PM marked A1 receivers were made by Colt or Elisco for the Philippines.

Any markings on the barrel?

That adjustable gas tube was made by Fulton Armory if I’m not mistaken..

The barrel is marked bmp 5.56 NATO 1/9 hbar (looks like it's a bushmaster barrel)

Bushmaster barrel if it's BMP marked, Bushmaster did a lot of 1/9 HBAR barrels.

No markings on the bolt or BCG that I can see but it’s in nice shape with matching gray park.

I guess it was someones parts gun build and not a Colt factory upper slapped onto a PSA pistol lower
I have a gray Nodak spud lower in the safe that I did a form 1 on a few years ago.
This should still make a pretty nice rifle.

I had a brand new nodak gray charging handle along with some colt 6 hole HG and N1 stock in my parts bin.
I think they look pretty good, might scuff the CH a little to match the rest of the rifle

Still a nice trunk gun

Nice!

I kind of dig the look of heavy barrel commando length guns

Thanks!
I'm going to see how she shoots with the Bushmaster HB and keep my eyes open for a proper colt barrel.
At least it's a complete rifle now and not just a lower in the back of the safe.

I decided to swap out the A1 upper for a colt A2 that was a better fit to the nodak lower. The take down pins on the A1 were too tight to take apart without a hammer and punch plus the gray park on the A2 is a near perfect match.

I’m really happy with it now. The fit and finish are great.
