Quality lower parts kits, triggers, receivers, handguards, BCGs, 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 (or even if you just bought a stripped lower), 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. We also carry a selection of pistol braces and buttstocks to throw on that naked buffer tube.
Need better groupings? The easiest way to upgrade your new AR build is with a drop-in trigger. We carefully selected some of the best units on the market. Any of these drop-in trigger units will reduce trigger pull and creep, minimize or even eliminate takeup and over-travel, and provide more consistent trigger pulls so you can land rounds more precisely. Best of all? They install easily and they're incredibly affordable. It's one of the first upgrades we recommend, especially if you're installing a lower parts kit.
Building an AR piece by piece? We've got you covered. Grab one of our mil-spec, forged, stripped uppers and a quality M16 bolt carrier group to get started. Pair it all up with a nice free-float, lightweight handguard and then all you need to do is pick a barrel to send rounds downrange. You don't have to purchase a complete build kit from us. We love supporting builders who choose to assemble their own uppers.
Grab Your Gunsmithing Tools, Too!
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.
