The Magpul ACS-L carbine stock for AR-15, M16, and M4 platforms is a purpose-built AR stock that strips away excess bulk while keeping the features that matter most. If you're running a rifle-length tube and want a lighter, more maneuverable rear end without sacrificing shootability, the ACS-L delivers. It's the streamlined take on Magpul's proven ACS design—less weight, less footprint, same rock-solid fundamentals that have made Magpul stocks a standard in duty and sport shooting.

The ACS-L retains the wide, sloping cheekrest that gives you a natural, repeatable weld in any shooting position. The friction-lock mechanism keeps the stock locked down after you extend it, killing that annoying rattle that plagues loose-fitting stocks. You get a QD sling attachment point built into the toe and a reversible socket for quick-detach pushbutton swivels—real options for how you want to sling your rifle. The aft compartment stays, giving you a spot to stash batteries, matches, or a spare bolt carrier key. The thick rubber recoil pad absorbs punishment, and it's user-replaceable if you ever want to swap it out for a different Magpul pad.

Note: This stock is designed for mil-spec (1.14" O.D.) carbine buffer tubes. The tube, buffer, receiver extension nut, and action spring are not included—you'll need those separately. Stealth Gray finish matches modern builds without drawing attention. If you're modernizing a carbine or building lean and efficient, the ACS-L is a no-nonsense choice backed by years of real-world use.
