MAGPUL ACS Rifle Stock Milspec-MAG-370

*3 Free Magpul Dummy Rounds with stock purchase* MAGPUL ACS Mil-spec Size Stock for AR15/M4 INTERNAL STORAGE COMPARTMENT - The ACS™ features an internal storage compartment large enough for basic weapon maintenance/cleaning supplies, spare parts, or other small items. BATTERY STORAGE TUBES - The ACS™ has two battery tubes, allowing for storage of six (6) CR123 or four (4) AA batteries in total. Batteries are accessible via rubber caps without removing or adjusting the stock. FRICTION LOCK - Similar to the Magpul CTR™ stock, the ACS™ features a friction locking mechanism to secure the stock and eliminate excess wobble and movement. Mounts on Mil-Spec AR15/M16 carbine receiver extention (buffer tube) (including; Colt, BCM, CMT, LMT, Vltor, Stag) Magpul Adaptive Carbine Storage stock is a medium weight at .75lbs. For comparison, the Magpul CTR weighs in at .57lbs, and the Magpul UBR comes in at a more hefty 1.25lbs. The stock is polymer, and similar in material to other Magpul stocks, which should make for a stock which can hold up to more than its fair share of abuse. It also has multiple compartments for storage, more about that a little later. The Magpul ACS continues in the CTR tradition in that is uses a cam lever which locks the stock to the carbine receiver extension (buffer tube).
