The Harpoon .300 Blackout represents Triton Arms commitment to advancing technology’s for the AR platform. We are proud to introduce our version of the .300 AAC Blackout thru the Harpoon Line.  With over 12 months of R&D on our barrels, and components, this system was designed to shoot 30 caliber projectiles from the AR platform without a reduction in magazine capacity and utilizing the standard or existing bolt. An extremely efficient Close Quarters Combat weapon, full power 115-125 grain ammunition matches the 7.62x39 AK round, and eclipses the 5.56 with much higher mass bullets, for a more dramatic effect on the target. With the use of sub-sonic rounds 225 grain Sierra open tip match for optimal use with sound suppression, vastly outperforms the 9mm MP-5 in penetration and down range accuracy. Due the high efficiency of the cartridge, it burns less powder than the 5.56 which results in a rifle that is comfortable to shoot, and very accurate even with a short barrel.  All Harpoon feature as standard issue Triton Arms TAR-15 Lower and UR1A4 Upper Receiver precision machined from 7075 T6 Aluminum Forgings, Triton Arms “Original Armory” TriDox® Barrels 4150 CMV Steel, or 416R Stainless, in Button Rifled or Cold Hammer Forged, M4 or M4A1 profile with 1/7 twist.
