One of my favorite stocks have tried many others but always end up going back to b5

Better alternative to the other one, both in cost and features (qd socket.)

Wide, durable and I like the storage compartments. Would not use it on a small rifle tho. Balance wise, this belongs on longer precision built guns, and the standard b5 is much better for running around.

Favorite stock. The storage compartments are kinda useless other then for small snacks (pepperoni sticks) but solid cheek weld and good QD sling point.

SOPMOD feels so good against my skin as the timer beeps.
