Great purchase
The 1:9 twist barrel shot accurately with 55g .223 and 62g 5.56x45 4-41/2” groups at 100 yds and the price was awesome along with the shipping. Couldn’t be happier.
USNBS is awesome
The NBS way is a great option for any build. Fits a little tight - which may be a good thing after all.
USSo far so good!
Seems accurate so far. Nice piece and as described
USAbsolutely perfect
This was the first barrel ive purchased. I chose the 1:9 twist based on ammo available near me. It shoots good and barely any clean up after 200 rounds.
