FREQUENTLY ASKED QUESTIONS
When selecting a caliber for one of our muzzle devices, the correct choice is based on your cartridge’s actual bullet diameter. For example; if you have a .300 Win Mag, you would select a 7.62/.308 muzzle device. This is because the bullet for that cartridge is a .308″ diameter.
At 16″, the EFAB has a marginal advantage in both flash suppression and recoil reduction compared to the AFAB. When measuring barrels at 14.5″ and below, the EFAB has a substantial advantage, and maintains that performance down to about 10″. Therefore, we recommend the EFAB for most applications utilizing SBRs, AR pistols, and bullpups. However, the EFAB can absolutely still be used on a 16″+ barrels if you want the most performance possible between the two.
