Reviews & Ratings for JE Machine Tech AR-10/LR-308 Muzzle Brake — 2 reviews — Page 1

No tooling or machine marks, I think this muzzle device is cast steel as it has a fine engine block texture to it. The finish is thin and shows marks easily. Even out of the box it has it's blemishes. Functionality wise it works fantastic for recoil reduction and like any other tanker style brakes it makes your gun extremely loud. Especially for indoors or outdoor bays with other people next to you. Thus not recommended for a home defense gun. Would not recommend this for heavy duty use or high accuracy platforms due to being a cast part and not machined.
I DO recommend this for budget builds, truck/hog guns, and PCC platforms. I love this on my AR9 9mm but will be replacing if for something that won't shatter eardrums indoors when used for home defense.

I’ll start this off by saying I actually really like this brake, it’s small and light and suits my lightweight AR very well. With that said, there were a few issues I encountered that I think a would be buyer should be made aware of, first there is no crush washer included, which is to be expected with a brake at this price but I thought I’d put that out there, luckily I had plenty of unused crush washers lying around so this wasn’t an issue. Second, the finish is not that good on it, installing it with a proper sized wrench and with the correct amount of torque, I still marred the finish on the brake and there’s not much I can do about that. Lastly, and this is probably the worst thing about this brake, is that it fit on rather loose, so timing and alignment was somewhat of an issue, but luckily I was able to remedy this with a good amount of grease , a great crush washer and a good eye. With all that said, this is a fantastic brake and the machine work is solid, no sharp edges to cut your fingers in and no flakes or burrs that I can see. Once it was fitted, it stayed on rock solid and aside from a few marks left when installing, it looks really solid. If it wasn’t for the loose fitment initially, I would have given this five stars
