Note from manufacturer: With the popularity of 300 BLK caliber SBR's / Pistols and the many different barrel lengths associated with these configurations which may affect proper cycling, users should be aware that all testing of this ammo is done on a 10.5" barrel with optimum results. As it is designed for use in rifles, American Marksman will not be responsible for cycling issues resulting from firing from a SBR / Pistol with barrel lengths less than 10.5"
