Cross Armory
Cross Armory builds affordable upgrade parts for Glock and P80 pistol builders, covering everything from drop-in triggers to full internal pin kits. The lineup centers on flared magwells, extended magazine catches, slide locks, and magazine extensions in a range of anodized colors, plus fiber optic sights and RMR adapter plates for red dot setups. A small AR-15 line rounds things out with a two-stage drop-in trigger and a takedown pin kit — giving builders an affordable way to personalize a Glock, P80, or AR-15 build.

What Cross Armory Builds
Cross Armory is primarily a Glock and P80 upgrade-parts brand, with color-anodized internals, sights, and controls designed for shooters building or customizing their own pistol. A small AR-15 line — a two-stage drop-in trigger and a takedown pin kit — extends the same builder-focused approach to the rifle side.
Cross Armory Glock and P80 Pin Kits and Controls
Cross Armory's core catalog is internal parts kits for Glock and P80-frame builds: 3-pin and 4-pin sets in steel, extended slide locks, and extended magazine catches, all available in black, silver, gold, red, and rainbow anodized finishes. The 3 Piece Upgrade Kit bundles a pin set, extended magazine catch, and extended slide lock in one order — the fastest way to refresh a P80 or factory Glock's internals in a single purchase.
Cross Armory Magwells and Magazine Extensions
Flared magwells speed up reloads by widening the mag well opening, and Cross Armory offers them in Gen 1-3 and Gen 4-5 Glock fitments across several anodized colors. Magazine extensions add 5 rounds of capacity to Glock 17 and Glock 19-pattern magazines in matching black, silver, gold, and red finishes — useful for competition shooters or anyone who wants more capacity without buying a new magazine.
Cross Armory Triggers and Optic Mounting
The Enhanced Flat Faced Trigger and Glock Performance Trigger are drop-in replacements for Gen 1-4 Glocks, aimed at a lighter, more consistent pull than the factory trigger. For red dot setups, Cross Armory sells RMR adapter plates and its own RMSC optic, plus fiber optic front sights in standard height for improved visibility over factory sights.
Cross Armory AR-15 Parts
Cross Armory's AR-15 offerings are smaller but built to the same standard: the Tac 2 flat-faced, two-stage drop-in trigger and a Mil-Spec 7075 T6 aluminum takedown pin kit for rear takedown pins — both easy first upgrades for a stock AR-15 build.
