Parts & Tools

Quality parts kits, gunsmithing tools, and AR-15 accessories.

Welcome to the parts counter. Need some roll pin punches to complete that LPK install? Or maybe you want to ensure your handguard's on snug and torqued to spec. Need to upgrade your new black rifle (or pistol) build with a better trigger, grip, or sights? We've got you covered. No 80% lower project is going to be easy without the right tools, so we sourced all the extra bits and components you'll probably need to make the job easier.

Triggers & Receiver Components

Once you've fabricated that shiny new 80% lower for your AR build, you've got to outfit it with all the components required to make it function: A trigger, hammer, disconnector, safety, and all those little springs and pins. Make it easy and remove the guesswork by checking out our selection of mil-spec AR lower parts for your .223, 9mm, or .308 80% lower receivers.

Handgun Parts Kits

The 80% game is no longer reserved for long guns. With quality 80% frames made for GLOCK pistols, the 1911, and Sig's modular P320, we worked to bring preconfigured parts kits to market so you can complete your build confidently. Check out our handgun parts kits here. They come with the parts needed to assemble your frame so you can hit the range. Parts are sourced from top gunsmiths and OEM manufacturers to guarantee accuracy and reliability.

Gunsmithing Tools & Accessories

Ever try to install an LPK without punches? You probably wound up losing some of those tiny roll pins, halting your build. Get rid of the frustration and guesswork and grab the tools you need to confidently attack your 80% project. We've got quality Armorer's Wrenches, torque wrenches, roll pin kits, vise blocks, and all the other gunsmithing tools you need to go from a hunk or aluminum or polymer to a locked n' loaded shooter. Grab a complete Armorers Kit like the Wheeler set, and you'll have virtually all the tools required.
