T4 Terminator muzzle brakes are designed for .338 Lapua Magnum to 375/408 Cheytac on barrels up to 30mm diameter. Standard hole size 6mm, must be opened up to correct calibre by a Gunsmith.

• Standard threads 3/4×24
• T4, 31mm Diamater, 90mm Long, 220-230 Grams

All brakes have flats for a spanner and so they can be easily fitted by the gunsmith. Ports are 90 degrees to the ground to ground disturbance. The ports are angled back away from the shooter to minimise shooter discomfort and maximise performance. The through hole requires opening up to 0.025-0.030″ over calibre size.

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