Mil-spec AR-15 buttstocks and pistol braces.
Getting a good cheek weld on your AR with the proper length of pull is what makes your sight picture consistent and your accuracy better. We've sourced a quality selection of carefully-picked AR-15 buttstocks and braces for your rifle and pistol builds. Setting up a barreled upper assembly with a stripped lower? Grab our Classic LPK with buttstock and buffer included.
We choose to sell mil-spec stocks since they guarantee fitment with almost all AR-15 lower receivers and buffer tubes on the market. Each stock and brace we sell is guaranteed to fit any AR parts kit or rifle or pistol build kit on our site! We've partnered with top stock maker Magpul to offer up their popular CTR Carbine and PRS GEN3 stocks for lightweight and bench rifle builds.
Need an AR pistol brace instead? We're offering up SB Tactical's hugely popular SBA3 Pistol Brace. It, too, sports mil-spec fitment and includes a buffer tube to make assembling your pistol lower easy. Although the ATF has proposed redefining certain AR-15 pistol configurations as SBRs (short-barreled rifles), pistol braces as standalone units remain legal without any paperwork required.
We're excited to offer up the ARH300 Folding Stock Adapter from Sylvan Arms! This unique buffer tube/receiver adapter works with standard buffer tubes and lower receivers, utilizing a heavy duty steel locking swivel pin operated by a spring-loaded button. Simply depress the button and fold your stock to the side of the receiver! Slap it back into position and it automatically locks up, aligning the buffer assembly with your bolt and receiver. Best of all? The stock adapter works with all AR builds! That includes all AR-15 variants (like 300 BLK, 9mm, and Grendel) and the LR-308 platform.
