The new Advanced Armament Flash Hiding Front Cap is for those pesky SBRs and running and gunning under NODS. This cap does eliminate a lot of the flash that would come with standard ammo on a SBR platform. Made from 17-4 H900 steel and coated in Nitride, it can handle any environment. The cap is bored out to a 6mm projectile and will work in both the Ranger 5 and the Ranger 7 silencer. Just please double check the front cap before firing when running on the Ranger 7 and make sure you have the right cap for the right caliber. This is a must have for anyone under NODS when running either the Ranger 5 Mini or standard Ranger 5.
