The Short Barrel uppers less than 16" comes with a Black H2 buffer. Make sure to use ONLY this buffer in any SR25 lower so the gun functions properly with the shorter barrel. (I Cannot and Will Not sell a Short Upper and a Lower with a Stock on it!) That is an Illegal SBR! Knights Does Not Make a Factory Pistol. Each lower Leaves Knights as a LOWER RECIEVER ONLY! IT IS NOT A PISTOL OR RIFLE,ITS A LOWER RECEIVER AND YOU MUST USE THE "OTHER" BOX ON THE ATF 4473. THEN YOU CAN LEGALLY MAKE AN SBR.
You can Form 1 the Lower as an SBR AFTER YOU RECEIVE IT. IT IS ILLEGAL TO PUT A SHORT BARREL UPPER ON YOUR LOWER TILL YOUR FORM 1 IS APPROVED FROM ATF!ALL NFA RULES APPLY*

32CrMoV12-10 is a high-strength European-standard alloy tool steel with a higher chromium content, whereas 4150 is an American-standard, medium-carbon chromium-molybdenum alloy steel. Both are widely used for demanding applications like firearms barrels and high-stress machinery parts, but 32CrMoV12-10 generally offers superior toughness and fatigue resistance.
32CrMoV12-10 (often related to GKH® or ARMAD® grades) is a high-performance chromium-molybdenum-vanadium alloy steel specifically engineered for advanced gun barrels and cannons, offering superior strength, toughness, and thermal stability compared to traditional, lower-alloy cannon steels. It is designed to withstand the high pressures, temperatures, and wear generated by modern, high-velocity ammunition.
