Why This Upper Matters
The 22 ARC cartridge offers shooters a compelling middle ground. It delivers rifle-like ballistics with moderate recoil, making it suitable for precision work and general shooting. The stainless steel barrel ensures consistent accuracy over extended shooting sessions, while the free-float design isolates the barrel from handguard pressure for improved precision.
The ambidextrous charging handle and M-LOK rail system reflect modern ergonomic standards. Whether you're building a new rifle or upgrading an existing lower receiver, this complete upper provides everything needed for a functional, accurate shooting platform.
