    Designed for Compact PDW Style Weapons - Featuring a Sloping Cheek Weld for Superior Comfort

    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 short and slim 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*.

    Made in U.S.A.

    • Dual-side release latch provides easy adjustment while remaining anti-snag

    We aim to please! Glad you like the product John, and thank you for the feedback.
    Love it, but....

    I received the stock very fast, shipping was amazing. It fit my gun perfectly. The color however, left a bit to be desired. The stock pictured is clearly gray, while the one I received has an almost blueish tint to it. It matches the pistol grip I ordered along with it perfectly, so I'm sure its magpuls issue. I was just expecting a light, battleship grey color. I still love the stock and it doesn't detract from my build. Just beware that the color in the picture doesn't match reality.

    We are sorry the color pictured didn't match what you received. We will look into this and fix it for others.
