Magpul Designs the Best

The MOE SL-K COLLAPSIBLE MIL-SPEC CARBINE STOCK gave my build the look I was looking for. The stock gave me the profile, cheek weld and length of pull management I need for my build. Coupled with Magpul reputation, this was definitely a winner.

Great compact stock

After buying one of these for a SBR, I bought two more on sale for other SBR's I own. They are just the right size for a compact rifle; they fit well and don't rattle. Brownell's was out of stock of the Black color, so I tried the gray; it's close enough to black to work.

BUY THIS

Amazing, perfect size, and great value. Fits tight/no wobble on mil-spec tube (brownells) and adjust easy. This is miles easier to adjust than the regular Moe SL but is ever so slightly looser, which is perfect cause the SL is too tight, this is perfect no wobble lock up and easy to adjust. Collapses fully on a 6 position tube, small size helps to get into quick shooting position with eyes through sights. Best stock out there, everything done right on this bad boy, buy it!
