Custom Ammunition - M4 Jackhammer

This new EBR round is designed to feed and function M16/M4 weapons in this caliber in both semi and full auto. It utilizes a proprietary EBR 220 grain FMJ projectile. Also works in Kalashnikov weapons with slight ramping. Cycles both weapons with or without a suppressor. Independent testing has given sub-1/2 MOA accuracy at 100 yards using aimed, semi automatic fire. Light recoil and enhanced controllability make this ammunition extremely effective in full automatic mode. A true breakthrough in "sub-sonic" ammunition in this caliber.

Warning! Do not fire any sub-sonic rifle caliber ammunition in H&K firearms or any firearm which has a fluted chamber. This type of chamber prevents cartridge case obturation, allowing, allowing propellant gasses to escape out of the breech, and possibly sticking a projectile in the bore. Subsequent firing with a bore so obstructed can cause serious injury or death.
