The Magpul ACS-L carbine stock is a purpose-built, lightweight receiver extension designed for AR-15, M16, and M4 platforms running a mil-spec buffer tube. If you're building a carbine that needs to stay nimble without sacrificing control, the ACS-L strips away weight and side storage to give you a slimmer profile while keeping the ergonomics that made Magpul's ACS line popular on tactical and hunting rigs alike. This is the stock for shooters who value compact handling over extra compartments.
The ACS-L retains the wide, sloping cheekweld surface that locks you into a consistent sight picture, whether you're running a red dot or a scope. The tail storage compartment stays intact—handy for a spare battery, cleaning patch, or round count. Magpul's friction locking system grips the buffer tube securely once you've set your length of pull, so there's no rattle or creep during shooting. The reversible QD socket accepts standard pushbutton sling swivels, and a 1-inch sling loop is molded into the toe, giving you two ways to rig the stock for your carry preference.
The rubber recoil pad is user-replaceable, so as it wears or if you want a different thickness, Magpul Tactical Recoil Pads are available separately. Keep in mind this stock requires a mil-spec carbine buffer tube (1.14" O.D.)—the tube, buffer, receiver extension nut, and action spring are not included, so factor those into your build if you're starting from scratch.
Available in OD Green, the ACS-L is a no-fuss, field-proven choice for hunters, sport shooters, and builders who need a dependable stock that won't slow you down.
