What is the B5 SYSTEMS - AR-15 Enhanced SOPMOD Stock Collapsible Mil-Spec Gray?

Currently employed by the U.S. military, this reinforced polymer stock fits M4-type receiver extensions and offers an improved cheekweld designed for increased comfort and consistency. Two waterproof storage compartments running the length of the stock hold 2 AA or 3 CR-123 batteries. Streamlined contours resist snagging on clothing, equipment, or vegetation to aid in safe and stealthy operation. Sure-Grip stock latch ensures convenient and intuitive length-of-pull adjustment, while the anti-slip rubber recoil pad secures the weapon to the operator’s shoulder. Features a black, stainless steel QD swivel mount and two molded 1¼" wide sling slots.

love the cheek weld
originally just bought to have a matching stock in RAL8000. i had grown quite fond of the BCM gunfighter (still like it a lot and prefer it's storage compartment) but this one surpasses it a little for me. very tight on the tube like the gunfighter. easier to get on/ off the tube, and a very comfortable and superior check weld.
