Are you kidding me??

8 positions!! Are you kidding me!! There's 8!! Need I say more?? The fit of this is superb. The quality manufacturing is awesome. Did I mention 8 slots to be as picky as you want. What else can I say, I'm impressed. I mated with a PSA lower and a Daniel Defense stock. Couldn't be happier.
