no it is not The 6 mm Advanced Rifle Cartridge (6×38mm), or 6mm ARC for short, is a 6mm (.243) caliber full-power rifle cartridge introduced by Hornady in 2020, as a low-recoil, high-accuracy long-range cartridge designed for the AR-15 platform. 6mm Remington is sold out everywhere I looked here are the ones Buds carries budsgunshop.com/search.php/type/Ammunition/caliber/10000793/sort/per-round-asc />I suggest that you use the "notify me " tab and buds will email you when its in stock

Joseph, no Sir, this is an entirely different cartridge and is not interchangeable. You can find 6mm Remington ammunition here (just scroll down) -- (6)un(8)roker.com/Rifle-Ammunition/search?Keywords=6mm%20remington&Sort=13&PageSize=96 ------------ ***Note*** replace the (6) & (8) with g & b to get the link to work. Cheers and stay safe!

Randy is correct, they are not the same, I found a couple of 6mm Rem in stock here
They are spendy.
