Hornady Black 5.56 NATO 75gr InterLock HD SBR is built for 10.5" to 11.5" short barrel rifles. It uses a proprietary propellant and a bullet that borrows technology from the Critical Duty FlexLock design, and it was built to meet the requirements of the FBI protocol.

The load runs well in SBRs suppressed or unsuppressed, with virtually no flash or residue, a reduced sound signature, and no fouling or overheating of suppressors. Listed muzzle velocity is 2321 fps. Sold as a 20rd box.
