YHM flash hiders reduce muzzle flash by up to 99%. Our tried and true Phantom flash hiders come in a number of varieties ranging from 5.56 mm, 7.62mm/.30 cal, 9mm, and 6.8 mm caliber options.
We also carry Phantom and sRx Q.D. flash hiders if you would like a flash hider to mount your suppressor system to!
We offer a variety of muzzle brakes ranging from our Low Profile Brake to the Annihilator to our muzzle brake/compensator combos. Our muzzle brakes are compatible with a variety of calibers including 556, 30 cal, 9mm, and 7.62x39mm.
We also carry Phantom and sRx Q.D. muzzle brakes to efficiently mate your suppressor system to!
Our Phantom® compensator brake and muzzle brake hybrid will help mitigate your rifle’s recoil and muzzle rise. We have multiple compensator/muzzle brake combinations for 9mm, 556, and 30 caliber rifles.
We offer multiple thread protectors for both rifles and pistols. Our thread protectors are either plated black (their part numbers end in B) or come in a stainless steel finish (no letter at the end of the part number). We also provide thread protectors for the threads on our Phantom® and sRx Quick Detach mounts.
We offer multiple crush washers and shim options to match the appropriate diameter of your barrel. There are .308 (⅝ inch diameter) crush washers, 5.56 (½ inch diameter) crush washers, and low profile (½ in diameter) crush washers.
Our shims come in packs of six with varying thicknesses for ½ inch-diameter shims while our ⅝ inch-diameter shims come in packs of 8.
Since crush washers work through the compression of their material, it is recommended that you replace the crush washer every time you remove or replace your muzzle device.
Crush washers on AR-15s are used to help secure a muzzle device to the firearm. They do this by allowing the muzzle device to be torqued down far enough to compress or crush the washer.
This helps mate the device to the rifle, but it is very hard to manually do this without introducing some minor variance in the device’s position on the barrel. This does not matter for most muzzle devices, but for things like sound suppressors, it can result in baffle strikes. To avoid baffle strikes, do not use a crush washer with your suppressor.
Barrel shims are used when it is necessary to orient the rotation (time) of the muzzle device to the firearm and you cannot risk introducing any misalignment. For example, when mounting a Q.D. muzzle device for a silencer.
A muzzle device is a specially designed accessory that attaches to the barrel of a firearm to modify the performance of the gun when it fires. This can be to mitigate recoil, muzzle flash, or some combination of the two. Other muzzle devices can affect the sound of the gunshot.
Muzzle devices are divided into four major categories: flash hiders, compensators, muzzle brakes, and suppressors. Some variants combine compensators with either flash hiders or muzzle brakes.
Some locations do ban muzzle devices and some muzzle devices like suppressors are heavily regulated depending on your location. However, most locations will allow you to have a muzzle device, check your local laws before purchase.
Thread protectors prevent the threads from being damaged when an accessory is not installed.
Yes. You can shoot your firearm with the thread protector on and it is recommended to do so if you don’t want your barrel’s threads to get dirty or damaged.
Thread protectors will not impact performance if they are secure when firing your weapon. The weight of thread protectors will not affect accuracy.
YHM® was founded in 1951 by Wallace Judd and James Graham, in an area of Massachusetts known locally as “Yankee Hill.” James had recently finished a tour of duty in Korea and saw an opportunity to help those he served by manufacturing firearms and accessories.
Through years of dedication and adaptation, YHM® has managed to keep those original goals in place while also becoming a full-service OEM Manufacturer.
Since 2013, Yankee Hill Machine has been owned and operated by the third generation of the Graham family-brothers, Chris and Kevin. Today, their mission is to offer high-end, durable products at an affordable price without sacrificing quality. All products are made in the USA and designed to exceed your expectations.
