Compact AR-15 Stock Kit for CQB and PDWs
The two-piece S4 stock comes with a complete set of all the parts you’ll need for finishing off your AR-15’s recoil system. This kit includes the buffer tube, carbine buffer weight, buffer spring, castle nut, and endplate, ready to install on your lower of choice. The S4 stock slides in with four-position adjustment with its unique, ultralight design, which is great for short AR builds where staying compact is key.

The detachable cheek piece enhances cheek weld, with a 2.23″ forward offset to aid in comfort and consistency. Simply adjust the cheek piece to where it’s the most comfortable by sliding it into the channel in the main portion of the stock. The stock also features a reversible QD sling cup in the rear, as well as a loop for traditional mounting.
If you’re interested in the stock by itself, check out the S4 stock in Black or Flat Dark Earth.
