Mil-spec pistol braces and buttstocks. Top makers. Affordable prices.

Completing your rifle or pistol AR and gaining more accuracy means investing in a good, stable stock or brace. We've got you covered with both configurations. Grab a super affordable M4-type, six-position buttstock for the classic look right here. We also carry top buttstocks from Magpul, including their bench rifle-accurate PRS Gen 3, and their popular, do-it-all CTR Carbine Stock. Want to build a portable PDW? We've sourced the unique Sylvan Arms Folding Stock Adapter, which allows you to collapse your AR's buttstock to a folded position alongside the receiver. This uniquely simple adapter requires no gunsmithing, and installs into your existing receiver.

Grab a Pistol Brace (While You Can)

We're also happy to provide the SBA3 Pistol Stabilizing Brace, a equality brace for any AR pistol. With a 5-position adjustable lever and wrist strap, the SBA3 is comfortable and affords better control and accuracy for any shooter. We even have the brace available as part of our upgraded Magpul MOE lower parts kit, which includes all components necessary to transform your fabricated 80% lower or retail-bought stripped lower receiver into a ready-to-function lower assembly.

Want to make an SBR? Here's how to legally convert a pistol into a short-barreled rifle.

Every is Mil-Spec in Fitment

Virtually all modern AR platforms and components adhere to the typical mil-spec fitment, especially when it comes to our 80% lowers and just about every buffer tube on the market. That's why all stocks and braces we sell also provide mil-spec buffer tube fitment. They're all compatible with our rifle kits and pistol build kits, and all standalone buffer tubes and buffer kits we sell.

"Are pistol braces legal?"

Currently, under federal law, yes. Although ATF policy made change and require ARs equipped with pistol braces to be registered as NFA firearms, owning a brace is not a felony. Always follow local, state, and federal laws when it comes to configuring your AR-15 and never install components that would violate any gun laws. Be aware that the ATF is reviewing the legality of pistol braces, and may consider the installation of a pistol brace on an AR-15 pistol to instead be defined as a short-barreled rifle (SBR). Owning an SBR without an approved NFA application is illegal under federal law.

Here's the full, updated guide on shouldering a pistol brace.

The ATF may say braced pistols are now SBRs. Here's a guide on their new rules.
