Gun Parts
Build, Repair & Upgrade • AR-15 · 1911 · Glock · AK · Surplus
Everything from a single detent spring to a complete lower parts kit. Keep Shooting’s gun parts bench runs deep across the platforms people actually build and fix — AR-15, 1911, Glock, AK, and Mosin Nagant — backed by one of the better military surplus parts selections online: VZ61 Skorpion components, holsters, mag pouches, slings, and hard-to-find rifle hardware. Add threaded barrels and thread adapters, sights and grips, springs and small parts, and the gunsmithing supplies to put it all together. If a part keeps a gun running or makes it yours, it’s here.
About Gun Parts
Keep Shooting’s gun parts catalog is one of the deepest corners of the store — hundreds of components spanning the most-built platforms in America plus a serious bench of hard-to-find military surplus hardware. Whether you’re replacing a worn spring, finishing a build, or restoring a surplus rifle, the part is probably here. Use the platform sections below to jump straight to what fits your firearm, and lean on our gunsmith tools to install it right.
Shop Gun Parts by Platform
The fastest way through a catalog this size is by firearm. Our AR-15 parts selection is the deepest — gas tubes, buffers and buffer tubes, bolt carrier groups, lower parts kits, springs, pins and detents, flash hiders, grips, stocks, and handguards, right down to the individual small parts that always go missing. The 1911 parts section covers the classic platform’s internals — barrel links, extractors, firing pins, hammers, sears and springs, thumb safeties, sights, and grips. For the most popular striker gun in the country, our Glock parts run from complete lower parts kits and locking blocks to trigger connectors, OEM firing pins, sights, and aftermarket barrels. And the AK-47 parts section keeps the Kalashnikov pattern fed with US-made trigger groups and the hardware to stay compliant.
Two more platform sections set us apart from the big-box parts sites. Our Mosin Nagant parts keep the classic surplus bolt gun shooting with cleaning kits and rifle tools, and the broad military surplus parts catalog runs to genuine VZ61 Skorpion components, holsters, magazine pouches, slings, bandoliers, and Cold-War-era hardware you simply won’t find on a mainstream parts wall.
Threaded Barrels, Adapters & Muzzle Devices
Running a suppressor or a muzzle device starts at the barrel. We stock threaded drop-in barrels for popular pistols — the Grey Ghost Precision G17 (1/2x28), the Backup Tactical P320, and the Ruger LCP II .22 LR barrel kit among them. If your pistol’s existing threads don’t match your can, our thread adapters and protectors convert common .22 pistols to the universal 1/2x28 standard and cap your threads when nothing’s mounted. Round it out with the muzzle hardware that lives in this catalog too — flash hiders, crush washers, and blank-fire adapters.
Build Kits, Springs & Small Parts
This is the bread and butter of any parts drawer. A complete kit like the AR-15 Lower Parts Kit or the Glock 19 Complete Lower Parts Kit gets a build to the finish line in one order, while individual springs, pins, detents, firing pins, and extractors cover the small stuff that wears out or walks off the bench. Trigger work is well represented too, from a US-made AK-47 Trigger Group to the Ghost Inc EVO Elite Glock connector. Pair any of it with the right gunsmith tools so the job goes smoothly.
Sights, Grips, Furniture & Mats
Beyond the internals, this catalog is where you make a gun fit you. We carry iron and night sights from makers like AmeriGlo alongside OEM Glock sights, grip upgrades from Talon Grips and Hogue, stocks and handguards for the AR and surplus rifles, and shotgun furniture for the Remington 870. There’s even platform-specific TekMat work mats to protect your bench while you wrench. For optics and aiming gear specifically, step over to our optics selection.
Pairing & Cross-References
Parts are half the equation. Feed the finished gun from our magazines selection, keep it running with the right gun cleaning gear, and finish the job with gunsmith tools. Everything here is part of our broader shooting accessories catalog — quality components at honest prices, with the same fast shipping and easy returns on every order.
