This upper is chambered for the high performance 204 Ruger cartridge, and uses a Button Rifled 1 in 12" Twist that is optimized for stabilizing 32-34 grain bullets, making it great choice for use in a varmint hunting rifle build. A Rifle Length Free Floating Aluminum Handguard rounds out the package and further aids to enhance accuracy potential by removing all shooter-induced pressure from the barrel. Comes complete and ready to fire with a single rail gas block, commercial bolt carrier assembly, charging handle, forward assist, ejection port door and shell deflector.
