Side Charging Precision Upper (Gibbz receiver)

Description

Overview

The BoreBuddy Complete AR22 Heavy Precision Upper delivers match-grade .22LR performance for shooters who demand precision and reliability. We build each upper around a heavy 18.5″ barrel and precision-machined receiver, then fully assemble and lot test to ensure consistent accuracy right out of the box. Unlike conversion kits, this is a dedicated .22LR upper designed to drop in on any standard AR-15 lower.
