This is a complete .45 ACP pistol platform kit built around a 7.5-inch barrel with a free-floating quad-rail handguard and includes a North Reach Whisper Pickle suppressor.

Perfect For

Suppressor-Ready Configuration

The kit arrives with the North Reach Whisper Pickle suppressor already integrated into the upper assembly. The suppressor features a step radial and 40-degree baffle design optimized for .45 ACP subsonic performance. The Hughes Precision thread adapter bridges the barrel's .578x28 threads to the suppressor's 5/8x24 interface, ensuring secure and repeatable mounting. Verify compatibility with your specific barrel threading before use, and ensure the suppressor is properly seated before firing.

Quad-Rail Handguard Ecosystem

The 10-inch free-floating quad-rail handguard provides mounting flexibility for tactical accessories without impacting barrel harmonics. The quad-rail design allows attachment of lights, lasers, grips, and other rail-mounted systems across all four sides. Free-floating construction means the handguard does not contact the barrel, supporting consistent accuracy and reducing vibration transfer. The anodized aluminum construction resists corrosion and provides a durable finish for extended use.
