INSTALLING & TUNING YOUR MUZZLE BRAKE
INSTALLATION
01
Rotate the muzzle brake lock ring onto the muzzle brake clockwise all the way until it stops.
02
Fit the muzzle brake to the barrel by rotating it clockwise onto your barrel all the way until it stops.
03
Align the muzzle brake so the ports are horizontal, and the flats are in the top and bottom position. This may mean rotating the muzzle brake anticlockwise a small amount.
04
Once in this position, rotate the lock ring anticlockwise until it contacts the thread shoulder on your barrel. Tighten in this position to maintain the muzzle brakes' alignment.
TUNING
Once a load or ammunition has been selected it may be desirable to tune the muzzle brake to tighten the grouping. There is a 50/50 chance that this will have a positive or negative effect on grouping.
01
Loosen the lock ring by rotating it anti-clockwise further onto the muzzle brake.
02
Rotate the muzzle brake anti-clockwise 180 degrees and align the ports horizontally and the flats are in the top and bottom position.
03
Tighten the lock ring by rotating it clockwise against the barrel thread shoulder.
04
Check grouping.
