Maximize the ballistic potential of your straight-walled hunting setup with the PRO2A LEFT HAND 10.5" 350 Legend Upper Kit. Specifically designed for left-handed operators, this system eliminates the persistent issues of facial gas blowback and stray casings by utilizing a mirrored left-ejecting receiver profile. The 10.5-inch barrel offers a significant velocity boost over ultra-short pistol configurations, making it a stellar option for medium-game hunting or custom home-defense builds where maneuvering in tight spaces is paramount.
