If you’re tired of all the bells and whistles and you’re ready for products that do the job they’re intended for in a superior fashion, you’re going to like CMT Tactical's low pro gas block. CMT Tactical makes the same parts that other manufacturers offer for the AR platform, but they do it better. The CMT J.A.G. Block line features superior manufacturing and improved functional design as well as finish like we’ve rarely seen before on a part that isn’t exactly a glory hound. It’s a shame to hide CMT Tactical’s J.A.G Gas blocks under a handguard. You just might rethink your build plans after you see this beauty.

Just Another Low Pro Gas Block but Better

CMT Tactical makes it their mission to fix the things that need fixing and create superior products for shooters who want more than just a Mil-Spec experience. When they designed the J.A.G. gas block line they create a gas block that would do its job without question and continue to do so even if it became necessary to change gas tubes. While other companies’ blocks utilize a blind gas tube hole, the CMT gas block is manufactured with a through hole. That means it’s easier to change out a worn or blocked gas tube without a hassle.

CMT Addresses Details That Matter

Unfortunately, not every manufacturer give the little things the attention they deserve. That’s not the case at CMT Tactical. Everything, right down to the set screws that secure the J.A.G. gas block is American made with quality materials. Whether you choose a .750” or .625” diameter CMT gas block you’ll get superior quality and performance from a wholly U.S. made product.
