MAGPUL AR-15 ACS STOCK COLLAPSIBLE COMMERCIAL BLK

Notify on availability

Description:

Upgrade your firearm with the versatile AR-15 ACS Stock from MAGPUL.

The Adaptable Carbine/Storage (ACS) stock is a drop-in replacement for the standard USGI M4 collapsible stock, designed to provide tactical operators with enhanced storage options, a secure and comfortable cheekweld, and an advanced dual-locking lever.

Key Features:

  • Sleek Design: Smooth, streamlined exterior contours prevent snagging on clothing, slings, or vegetation, allowing for quick exits from vehicles without gear interference.
  • Ample Storage: Removable battery storage compartments run the full length of the extra-wide comb, accommodating 2 AA or 3 CR-123 batteries while providing a solid, comfortable cheekweld.
  • Weather Resistant: Secure molded rubber caps keep water and dust out of compartments and are designed for easy removal, with a beveled exterior to resist snagging.
  • Positive-Locking Trapdoor: The trapdoor on the right side of the stock reveals a spacious compartment for additional batteries, cleaning supplies, ear plugs, spare parts, or other small items.
  • Advanced Dual Locking System: An additional cam lever protects the release lever from accidental operation, while still allowing for easy length of pull adjustment.
  • Sling Attachment: A slot molded in the toe provides an attachment point for a 1¼" wide sling.
  • Compatible Design: Mil-Spec fits 1.14" O.D. buffer tubes on Colt-manufactured M4 and similar mil-spec tubes, while the commercial version fits larger 1.17" O.D. commercial carbine buffer tubes.

Specifications:

  • Material: Reinforced molded polymer
  • Colour: Black
  • Overall Length: 77/8" (20cm)
  • Height: 5¼" (13.3cm)
  • Weight: 13.6 oz. (385g)
  • Buffer Tube Compatibility: Commercial fits 1.17" O.D. carbine buffer tubes

Note: Buffer tube, carbine buffer, receiver extension nut, and carbine-length action spring are not included.

Brownells USA Excellent Product 04/04/2011

This stock is simply amazing. It's a very good adjustable stock that's both comfortable and useful. The compartments for battery storage are also great for allen keys that allow for a quick removal of a broken holographic sight. PLUS you get a really cool Magpul sticker. :)
