The barrel is also a steal. As to 1/9, I did some Google searching on that, and Bill Alaxender, on this very forum hasd some very interesting commentary on that. That was a very consciously researched and selected twist. My own ballistic calculations show that 129+ is suboptimmally too heavy. 123 has better ballistics and hits harder, by the numbers. 129+ is just too slow, and will end up going subsonic at a shorter range than a 123 does . As to 1/9, in a 20", Bill picked that spec because he found that very forgiving to Grendel accuracy, while 1/8 was a lot more finicky.

I included their $60 overpriced flash hider in my order, and still feel it's a great price for a top shelf name brand BBL from the masters of Grendel.

FWIW the cotrovertial RedX has extended A2' FH for $10 as well, in the 9/16.
