Designed for calibres up to .22cal. These brakes are easy to install with no gun smithing required. Specifically manufactured to fit onto the CZ515, Ruger Precision, Savage and any .22cal firearm with a 1/2x28tpi thread and with a shoulder no larger than 21mm OD.

Installation:

The only required tool is a small shifting spanner.

First screw the locknut all the way onto your Grizzly Eliminator Brake.
Take your Eliminator Brake, and screw it on all the way to the shoulder of the firearm, taking care not to cross thread the muzzle brake.
Turn it back anticlockwise to the 11.55 position or thereabouts making sure that the vents are sitting almost horizontal to the barrel.
Hold the brake firm in the 11.55 position and with your free hand turn the locknut clockwise until it goes no further.
Hold the firearm firmly, and with the aid of the shifter, grab onto the flats of the brake and turn it clockwise until its nice and tight.
Be sure to check that its aligned square to the barrel and if necessary, repeat these steps to get it right.
Once tightened firmly, your muzzle brake is ready for use. After firing three shots check that it's still holding nice and firm.
The ports are angled back away from the shooter to minimise shooter discomfort and maximise performance.

The standard through hole is for .22 & requires opening up to 0.025-0.030 over calibre size if fitted to larger calibres.

Honestly how do you write a review of this product? I would have to run tests for years on multiple oils on various engines to do so. The value was good however and shipping was great

Works well. You need to drill a 3/8” hole
Appears to be well made, alignment bar slides in nicely. As stated, you need to drill a hole in the bar for the gimble bearing driver, the directions are not clear, what I did was before I take out the old gimble bearing, put an O ring on the bar close to the last step on the bar, slide the bar all the way in, then carefully slide the bar out, this marks the distance from the back of the gimble bearing to where the shaft on the outdrive bottoms out, move the O ring a 1/4” towards the stepped part of the alignment tool (this is so you won’t bottom out the alignment tool when driving the gimble bearing in) then slide the driver puck up to the O ring and use a 3/8” diameter transfer punch through the side hole in the puck to mark the bar. You need to drill a 3/8” diameter hole in the alignment bar, two V blocks, some clamps, and a drill press will make drilling much easier, after the bar is securely mounted and centered in the drill press, use a center drill, then 1/4” drill first, using plenty of oil, drill all the way through, then use the 3/8” drill, deburr both sides and you should be good to go. People complain that it doesn’t come pre-drilled, the reason is that not all out drives are the same so you have to fit it to the outdrive that you have. Fortunately, I have a machine shop at my house and have a jig setup with various drill bushings, but the method I described above should work for you. Just make sure you’re perfectly centered and secure before you start drilling.
