    Very nice stock, holds good cheek weld and doesn’t slip! Considered this or magpul and super glad I went with this!

    APE shipped my order quickly and I was very impressed with my B5 Systems Enhanced SOPMOD stock. Locks up well on my receiver extension, feels great while shouldered, and gives the benefit of having on-board storage for CR123 batteries, which is awesome if running a light, optic, etc. that takes them. My stock had the updated recoil pad that features the cutout for the Multitasker M4 Tool, which was an added bonus for me as I picked up an M4 Tool alongside my stock.

    This is a great stock at a great price. If you are considering changing out your stock this is the one you need to get!

    Great stocks. I wish they would make a model that would fit 18650 batteries. You can’t go wrong with B5.
