Aim Sports ARSTKCC Mil-Spec 6-Position Collapsible M4 Stock Kit - Black

The Aim Sports ARSTKCC is a complete Mil-Spec collapsible M4 stock kit for the AR-15 platform, bundling every component required to mount a buttstock on a standard carbine lower receiver. This assembly comes with the 6-position adjustable stock, a mil-spec carbine buffer tube, the standard carbine recoil spring, a standard buffer, a sling attachment end plate, and a castle nut - everything needed for a drop-on installation.

Built around a reinforced polymer stock finished in black, the assembly delivers the classic M4 profile with a six-position latch that adjusts the length of pull to fit a wide range of shooters. The included mil-spec buffer tube is machined to standard carbine dimensions, allowing drop-in compatibility with virtually any AR-15 or M4 lower receiver.

The stock features an integrated QD (quick-detach) swivel cup on the rear for modern push-button sling attachments, while the included sling attachment end plate provides an additional fixed loop on the rear of the receiver for traditional sling mounting. The castle nut secures the buffer tube firmly to the receiver extension threads. Aim Sports' combination of polymer and aluminum construction in this kit keeps weight reasonable while providing the components needed to complete an AR-15 carbine stock setup.

This is a New production accessory ready to drop onto any standard AR-15 carbine build.
