Okay, so maybe you do and maybe you don't have a lightweight machine gun or an M240 semi-auto clone. If you don't, you will wish you do.
Until then, if you have a need for a very heavy weight flash hider that measures a full 2.91", which as we calclulate should be enough to pin and weld a 13.7" recon carbine.
Either way, this flash hider is heavy, so be sure to have the right rifle to bear the weight. The underbelly of this flash hider features an A2 style birdcage that prevents dust flying up from barrel concussion on the bottom of the muzzle.
Installation Note: Recommended to be installed with crush washer, which is not included. Spacer and timing shims are good as well.
