Blem Handguard

The North Reach Manufacturing Micro-Pew 22 is a 6-inch, 1-inch diameter suppressor in 6061-T6 aluminum with a 300 series stainless steel adapter, finished in jet black Cerakote. It threads directly at 1/2x28 and is included as part of this complete upper. The Micro-Pew 22 is not full-auto rated.

Barrel and Upper Receiver

The 4.5-inch pencil profile barrel is a dedicated .22 LR unit with a 1/2x28 thread pitch. The 6061-T6 billet upper receiver features a Type III hard coat anodized black finish and forms the structural core of the upper assembly. The 7-inch freefloat M-Lok handguard surrounds the barrel without contact and provides M-Lok mounting positions for compatible accessories.

Bolt Carrier Group and Charging Handle

The included dedicated .22 LR bolt carrier group is stainless steel and specific to the .22 LR platform. The BCG and Mil-Spec M4 charging handle work together to cycle the action and complete the upper side component set needed to run this complete upper on a compatible lower receiver.
