The SilencerCo Alpha Direct Thread Mount (brand part no. AC1526) threads onto an M13.5×1 left-hand muzzle, giving shooters with reverse-threaded hosts a factory-matched mounting point for compatible SilencerCo Alpha-series suppressors. Left-hand threading is used on certain host platforms specifically to prevent the suppressor from backing off under recoil, so getting the correct hand of thread matters as much as the pitch itself. This mount is cut precisely to the M13.5×1 left-hand standard, not the more common right-hand pattern.

Key Specifications

• Cut to the M13.5×1 metric thread pattern in a left-hand orientation.
• Matches hosts with reverse-threaded muzzles, preventing loosening under recoil.
• Built specifically for the SilencerCo Alpha suppressor series.
• Weighs approximately 1.6 ounces, adding negligible weight to the build.

Frequently Asked Questions

Why does thread direction matter? Left-hand threading is used on certain hosts specifically to keep the suppressor from backing off under recoil, so it must match the host’s muzzle threading exactly.

Is this compatible with right-hand threaded muzzles? No, this mount is cut for left-hand M13.5×1 threading and will not fit a right-hand threaded muzzle.
