A new, unique, ambidextrous release latch minimizes rattle on the receiver extension without requiring additional locks, levers, or springs.

Fast service
quality product. I wish I had a cheat sheet to compare the features of the limitless variations of these stocks. I can't keep them all straight in my head. But, it fit perfectly and seems well made, as usual.

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.

Perfect for what I wanted
Perfect as a replacement stock, being a smaller man, I wanted something light weight and comfortable, the MOE S-K stock filled both of those requirements exactly as I was hoping for.

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.
