I just got a PTR 91 squad carbine model with the 16 inch fluted bull barrel and I'm not sure the twist rate on it. None of that information came with the gun as far as I know. I tried looking it up. I believe the 18 inch barrels have a 1 in 12 twist and the 16 inch barrels have a 1 in 10 twist...
SN of the PTR 91 I'm looking at buying is AW22XXX. Heard there were some serial numbers that should be avoided. Not sure if this one is safe.
It's a PTR 91 sc with a 16 inch fluted barrel
