Questions & Answers
What’s the overall length? Curious if this will work with a 13.9 and be legal? Expert Answer

The Yankee Hill Machine Yhm Low Profile Muzzle Brake is 2.225" in length and has a 0.735" diameter. The product's small outside diameter is great when pinning and welding the Muzzle Brake on a 14.5" barrel. Since it allows both the gas block and the handguard to be installed directly over the Muzzle Brake.

Does the crush washer come included, it's not clearly stated in the description Expert Answer

A crush washer is included.

Helpful Positive Review
Useful when you have to pin and weld by NewJerseyan, Verified Owner, December 8, 2020
I live in NJ, where you have to pin and weld any muzzle brake. This device allows you to change a gas block without removing the brake. Optics Planet had it in stock and shipped it quickly as usually.
