Cross Armory CRGOKRB 3 Piece Upgrade Kit P80 Gen1-3 Rainbow
The Cross Armory CRGOKRB 3 Piece Upgrade Kit for P80 Gen1-3 frames gives your polymer 80 build the refinement it deserves. If you're running a P80 lower and want to level up the ergonomics and functionality without a full rebuild, this kit packages three key upgrades in one shot. It's built for shooters who understand that the details matter—better grip texture, smoother controls, and a more refined feel make the difference between a gun that works and one you actually want to shoot.
Cross Armory has a solid reputation in the P80 community for quality parts that fit right the first time. This three-piece design keeps things simple: upgrade what counts, leave the rest alone. Whether you're breaking in a fresh build or refreshing an existing frame, the kit gives you a straightforward path to a more polished shooting experience. The rainbow finish adds visual appeal without compromising durability, and it's a way to make your build distinctly yours.
Installation is straightforward for anyone comfortable with basic P80 assembly. As always with polymer 80 builds, make sure you understand your local and federal regulations before ordering—P80 frames come with real responsibility. This kit is for builders who take that seriously and want parts they can rely on.
