I had picked up a m16a1 clone sometime back and the lower or i believe the rifle was a p.w.a. as the receiver is but assuming the upper and bolt carrier is cause their is no markings but has a colt 1/12 barrel and colt a1 front sight, I know p.w.a. went out of business in the 2000 and the receiver on mine is in the 2000 and I can date it back to pre pan era rifles. I seen past threads saying the lower receivers alone go for stupid prices, my question to anyone who has any knowledge on these rifles/receivers are they worth what I'm seeing online? I picked this rifle up for 500 so I am assuming I got a great deal with the colt parts as well
