You may have to settle and repair in that case. My first A2 was a Canadian issue from the armourer's shop and the rear sight protectors were damaged. They'd used it for chemical tests so the finish was damaged also. I cleaned down the ears, bead blasted it and sent it to Olympic for finish. They sent it back done and I assembled from there. That worked out fine...
Well perseverance/persistance paid off. The latest replacement arrived and what do you know an actual sound upper. Handguard missing a tooth (whos not?) and a cracked butt plate both of which I have replacements for so no more complaining. Now I can get in line at NODAK-SPUD and wait a while longer. Any opinions on barrel twist rate 1/12 vs 1/9 ?
Depends which bullet you intend to use. I have a 9" twist on my M4gery and it seems very accurate, a 7" gave me a bit of trouble with 55 gr bullets though. I don't think I'll ever be able to get or use current tracer so any ball I lay hands on should be fine out of 9". You should be able to get an early profile in 9" twist...
I may go with the 1 in 9. The 1 in 12 is "correct" but who is counting. It's an M164gery why not give myself a twist rate that will handle heavier projectiles. That and the fact that Delton has a 1/9 with the FSB attached has me leaning 1/9.
I like the slower twist for my 55gr deer hunting bullets. Less apt to have bullets come apart after impact. Otherwise, most all my barrels are 1-7".
I was having copper build up issues with 55s and 7" twist...very strange.
I feel fortunate that my only issue now is twist rate. I would have thought there would be a strong market for retro ARs and parts. Not so much. Just a couple of suppliers with parts kits,one company producing retro lowers/uppers and a couple of folks producing "pencil" barrels.
