The Accu Shot Rear Barrel Support is engineered for shooters who demand true, repeatable precision from their FX Impact M3–M4. Rear‑end barrel flex is one of the most overlooked accuracy killers — and this support eliminates it right where it starts.

By stabilizing the rear of the barrel, you lock in harmonics, reduce POI drift, and unlock the tight, predictable groups your platform was built to deliver.

Key Benefits

• Eliminates Rear Barrel Flex Removes the subtle rear movement that opens groups and destabilizes your shot cycle.

• Tighter, More Consistent Groups With the rear locked in, your barrel tracks straighter and repeats shot after shot.

• Cleaner Harmonic Behavior Less whip, less vibration, more stability — especially at higher power levels.

• Improved POI Stability Reduces wandering and drift caused by unsupported rear barrel movement.

• Drop‑In Fit for FX Impact M3–M4 No tuning changes. Install, torque, and shoot with confidence.

• Machined for Precision Built to match the tolerances and expectations of serious shooters and tuners.
