I finally got to see one today. I was really expecting a joke...
I gotta admit, the gun looked good! It had G.I. parts...it had been re-painted, had a great looking chrome line barrel, an A-1 upper (according to the dealer)...the barrel had the same diameter as my 20" Bushy,
Also had one of those "buffers" at the rear to "tighten" it up. The "muzzle tamer" was a joke...poorly welded on.
Colt parts...but could not tell about the barrel's manuf.
I gotta admit, for $550 they don't seem too bad. I have not purchased one (I'm AR poor already)...worth a look.
The dealer opened up the box while I was there and he seamed pretty happy with them (he's bought 4 to sell)
