Great for the price

Works as it should. Finish not perfect, but good enough. This one is all business. Does not include crush washer.

Good Product, fits as expected

Great muzzle device for the price, threads on as it should and the finish is good for the price. Does not include a crush washer so make sure you order one separately.

Works exactly as it should
