Heresy Design Silencer Timing Device - 1/2x28

Time your muzzle device or silencer mount in under 60 seconds with three washers instead of a 6-10 piece shim set. The Heresy Design Silencer Timing Device for 1/2x28 simplifies suppressor and muzzle device alignment while also preventing direct-thread silencer walk-off.

The Heresy Design Silencer Timing Device is a patent-pending 3-washer muzzle device timing system designed for 1/2x28 threaded barrels, replacing traditional shim sets for faster, more precise alignment.

You get a 3-washer system that produces 25 ft-lbs of torque at the alignment point with no additional torquing required, delivering precise muzzle device timing without the trial-and-error stacking of traditional shims. The washers also function as a retention system for direct-thread silencers, forming enough tension to prevent walk-off during firing. Installation requires no specialized tools or advanced knowledge and takes less than one minute.

Compatible with any firearm with 1/2x28 threaded barrels, including AR-15 rifles in 5.56 NATO, .223 Remington, .300 Blackout, and other calibers using 1/2x28 threading. Works with muzzle devices, silencer mounts, and direct-thread suppressors.

Machined from 12L14/4140 steel with black oxide coating for corrosion resistance. The 3-washer design eliminates the need for large shim sets and provides repeatable alignment with consistent torque values.

Ideal for timing flash hiders, muzzle brakes, compensators, and silencer mounts on 1/2x28 barrels. Also functions as a direct-thread suppressor retention device to prevent walk-off.
