The TT Terminator muzzle brake is KG Gunkoted Black & opened out as standard to take a maximum calibre size of .308

It is specifically manufactured to fit onto the Tikka CTR, Ruger Precision rifle, Savage, Bergara & rifles with 5/8 x 24 thread muzzle thread with a maximum thread shoulder of 21.4mm, 0.842”

Easy DIY fit, no Gunsmithing required, using the locking nut to index it to the barrel.

TT with nut is 25mm, 0.98” diameter, 72 mm, 2.83” long, 95 grams, 3.35 oz.

Ports are 90 degrees to the ground to minimise debris disturbance

The ports are angled back away from the shooter to minimise shooter discomfort and maximise performance.

The standard through hole is for .308 & requires opening up to 0.025-0.030" over calibre size if fitted to larger calibres.

A handy tip is to carefully cut up an alloy drink can then put a strip of alloy between the spanner & the brake flats to help protect its finish, lube muzzle threads before installation

If you would like to use some Loctite or similar please put it on the brake only, not the nut.

The TT performance is the same as the T3 Terminator Muzzle Brake.
