Easy-to-assemble handgun lower parts kits and springs.
So, they're "technically" frame parts kits. But with 80% lowers all the rage, these kits and springs have begun being called handgun lower kits. Either way, we're happy to provide quality, OEM-grade parts and spring kits for your completed GLOCK-compatible 80% frames. These components are guaranteed to fit any Gen3 GLOCK, as well as our available polymer 80% G-comp frames. Hit the link above to grab one!

Kits that include a barrel and slide are designed to be an "all-in-one" parts kit, made to pair up with your completed 80% frame or any Gen3 GLOCK frame. These kits allow you to finish assembly of your custom pistol, at which point you'll only need a magazine and ammo to hit the range.
MOA-Capable Barrel (optional)
We include 1:10-twist barrels with 11-degree target crowns in each Parts Kit. Barrels are available in carbon steel with a nitride QPQ treatment, or stainless steel.
GLOCK-Compatible Slide (optional)
Each slide is heat-treated to achieve a 41-44C hardness rating, and each features a nitride QPQ treatment for the best heat and corrosion protection against the elements and carbon fouling from spent powder and brass. Each slide sports OEM internal dimensions and specs, with Glock-compatible, OEM-style sight cuts.
Slide Options/Features
You may select a slide with rear serrations only, front and rear serrations, or a DLC-type slide with double serrations and a Trijicon RMR cut, which includes a cover plate.
OEM-Type Internals
In addition to selection an optional barrel and slide kit, you'll can opt for an internals-only parts kit which includes all internal slide parts, frame parts, and a Gen3 spring and guide rod. These internals include:
Please note: None of these kits include a frame, locking block, or magazine. You may opt to purchase separately one of our GLOCK-compatible 80% frames here.
