Dedicated .22 LR Precision Platform

This kit uses a stainless steel bolt group specifically engineered for .22 LR ammunition. The dedicated bolt ensures reliable feeding and extraction without the wear that comes from using standard .223 bolts with rimfire. The 16-inch barrel balances velocity with handling, and the pencil profile keeps the overall rifle light for extended shooting sessions.

Freefloat Handguard Mounting Ecosystem

The Avalon M-Lok handguard floats freely from the barrel, eliminating contact that can affect accuracy. The 15-inch length provides ample real estate for mounting optics and accessories, while slant port cutouts reduce weight without sacrificing rigidity. Partial top rail sections let you mount iron sights or a red dot without committing to full rail coverage.

What You Need to Know

Lower receiver not included. The kit arrives complete with upper assembly, bolt carrier group, charging handle, lower parts kit, buffer tube, buffer, recoil spring, castle nut, and end plate. You'll need a stripped lower receiver to complete the build. The A2 flash hider threads onto the barrel at 1/2x28, which is standard for .22 LR platforms. The six-position adjustable stock lets you dial in length of pull for different shooting positions or body armor.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
