Product Info for Breek Arms OPMOD AR15 Castle Blast Shield For Outside Threaded Muzzle Device

The OPMOD Breek slim-line Castle Blast Shield is a muzzle accessory designed to reduce the felt blast noise and concussion for the shooter and nearby operators while still focusing on keeping things compact and lightweight. The blast shield compresses tight to the back of the muzzle brake and directs the noise forward, downrange from the shooter. Anyone nearby on the range or in the field will appreciate the blast being re-directed away from them, improving their hearing and even reducing the burst of gas that can be felt from certain muzzle brake designs when a secondary operator is close.image

With the OPMOD Blast Shield installed it will reduce your muzzle brake's effectiveness. But if you are shooting alone or just don't care about the extra noise you are making, it can easily be threaded off and back on as desired. This allows you to pick the benefits you want in any circumstance, without requiring any tools to change anything out.
