T4 Brake

T4 Terminator muzzle brakes are designed for magnum cartridges up to 375 Cheytac, on barrels with a muzzle diameter up to 29mm.

The T4 Dimensions are, 1.14”, 29mm diameter, 3.54”, 90mm long, 6-6.5 oz, 170-185 grams

Standard threads are 5/8 x 24, M18x1, ¾ x 20, 24 & 28

The standard through holes are 7.5mm for up to .264 (6.5mm) & 9.3mm for up to a .338 & require opening up to 0.025-0.030″ over bore size if used on a larger calibres.

The T4 does not have a top or bottom & has flats for a spanner and so the Gunsmith can easily fit them.

Ports are 90 degrees to the ground to reduce disturbance & are angled back away from the shooter to minimise shooter discomfort and maximise performance.

It is recommended the rear of the brake be tapered down to the muzzle diameter when fitting.
