The QM Rear Alignment Bar Kit by Tanner is a precision chassis alignment tool designed for shooters who demand accuracy in their firearm setup. This kit is ideal for operators, gunsmiths, armorers, and competitive shooters who need to verify and correct barrel-to-receiver alignment without removing the barrel.
The kit features a rigid rear-mounted alignment bar that references the receiver's axis, allowing users to detect misalignment of the barrel extension, bolt carrier, and firing pin without subjective measurement. At 40.5 inches in overall length and weighing 5.3 pounds, it maintains structural rigidity while remaining portable for field use or gunsmith benches.
This tool is essential for professional armorers maintaining law enforcement duty rifles, precision rifle builders dialing in competition systems, and gunsmiths verifying barreled action concentricity. The design accommodates standard chassis platforms and AR-pattern systems, making it compatible with modern precision rifles used in law enforcement, military, and civilian tactical applications.
