A drop-in replacement buttstock for AR15/M4 Mil-Spec carbine buffer tubes, the SL-K is designed for compact PDW style weapons or users desiring a small and light stock.
Features a shorter and slimmer profile, a smaller rubber butt-pad with rolled toe for easy shouldering and sure grip, and a 1.25″ footman’s loop with the ability to accept an optional M-LOK QD Sling Mount for push-button style QD sling swivels. A new, unique, ambidextrous release latch minimizes rattle on the receiver extension without requiring additional locks, levers, or springs*.

Really like this stock, compact, light and durable

I really like this stock even on 16” rifles. I’d pay more for a built in QD socket and internal tensioner.

I bought this after having the SL-S which was a little too big for my liking. This one was perfect and looks and feels great. Never expect less from magpul and especially Big Tex. Great products and great prices.
