The Magpul MOE SL (Slim Line) Stock is a collapsible drop-in upgrade for your GBB airsoft AR-15 or M4 rifle, including WE Tech M4 gas blowback rifles. The stock is designed to be slim and streamlined, yet it still provides a sloping cheek weld for comfort. With dual-sided release latches, three options for sling attachments, a rolled toe, and an angled butt-pad, the Magpul MOE SL is tailor made for the modern airsoft player. Even while wearing modular gear, body armor, or an assault pack, this adjustable stock will sit deep and secure in the shoulder pocket. There is also an internal 'anti-rattle' feature that minimizes stock wobble and ensures accuracy. Installing this MilSpec buttstock is quick and easy, requiring no modification to the airsoft gun.
