From now on this will be the only product I use to install and time muzzle devices. This product is exactly what I was looking for. I tried multiple times fumbling around with peel washers and they just don’t work. They worked great and the instructions were very easy to follow. I used these accu-washers to reinstall 2 muzzle devices and it couldn't have been easier. Posted by Zak Llamo-Cohen on 20th Jul 2023 Well worth the price - perfect fit every time for alignment critical brakes Posted by Eben M Atwater on 14th Sep 2023

Had all the washers I needed to time the muzzle brake. I used it on my stag tac15 woth the precision armament EFAB muzzle device and I found the exactly right washer for the perfect tight fit. Posted by Kevin Collins II on 18th Sep 2023

RESOURCESįor full specifications, installation manuals, and more - visit our Technical Resources page: Higher torque installs may require holding the rifle in a barrel vise. The torque load specified in the instructions is merely the minimum required so your device does not rattle free, however you will need to continue to apply torque beyond this to achieve alignment. Since the Accu-Washer shims are used to adjust your brake in discrete intervals, it is inherent that the torque required for proper alignment will fall in a range. You may also apply some lubricant to each side of the shim as there is friction in the works here too. The coefficient of friction between the threads is what limits your rotation, cutting this coefficient in half with grease can give you twice as much rotation. We suggest you apply generously, then run the brake on and off the barrel a couple times to work it in, then wipe up any excess. Next, applying a moly-grease or CLP-type lubricant to the threads on the brake and barrel will provide further rotation for the same torque. Any contamination can limit the rotation.

Why aren't these included with my muzzle device?įirst, make sure the threads on your barrel and muzzle device are completely clean and free of all debris. The consequence of this misalignment is a baffle strike causing bodily harm at worse and impaired accuracy at best. This is very unlikely (for anyone who has installed one) when you're putting all your might into the 30-60 ft-lbs of torque they often require. This requires that the material is uniform and that you apply a perfectly pure torque load normal to the bore. More importantly, it relies on the principle that the washer will deform uniformly while it is being crushed. Firstly, crush washers come to a knife edge on both mating surfaces - it is likely for this reason that a muzzle device is already misaligned just sitting on the crush washer before it is even torqued down. However, our opinion is they should never be used on any baffle style muzzle device where the clearance hole is only slightly larger than the bullet. Note: The Accu-Washer Alignment System can be used with any brand muzzle device.Ĭrush washers are perfectly acceptable to use on any open aperture muzzle device, such as the standard A2 birdcage flash hider. Designed to fit 1/2-28 or 5/8-24 threaded barrels.

One Accu-Washer System will align approximately nine brakes (on average) before replenishment shims are needed. All shims feature an oxide blasted non-reflective surface finish for low visibility.

#AR 15 MUZZLE BRAKE WASHER SERIES#

Precision machined from high strength 400 series stainless steel to a guaranteed thickness uniformity of ☐.0001'. Includes 18 individually marked Accu-Washer™ shims (timing adjustable from 0-360 degrees in 20-deg increments) and easy to follow instructions. This minimizes the risk of baffle strikes, ensuring maximum accuracy and safety from your muzzle brake or suppressor. Since only one shim is required, the tolerance stackups and complexities associated with peel washers and other multi-shim systems are eliminated. Oh, and don't buy an aluminum gas block, only steel.Simply choose the correct size Accu-Washer® shim to accurately index your muzzle brake or flash suppressor while maintaining perfect bore alignment. You can also use Rocksett, though that can be a pain in the ass if you ever need to take off your gas block. A couple of scrap pieces of 2X4 in the jaws of a bench vise will work just fine.Īs far as the gas block, I just use a drop of blue Loctite (some people use red) and then torque to 30 in/lbs. It always good to have spares.Īlso, make sure to clamp the barrel in a vise during installation. All you need to do is make sure they go through a minimum of 90* (1/4 turn) rotation while crushing the washer before they index.ĭo yourself a favor and buy some extra crush washers to piggyback with shipping on your muzzle brake order. Don't use Loctite on the muzzle brake! Most muzzle brakes use a crush washer.
