This BCM stripped barrel is machined from a 410 stainless steel. It features hand lapped button rifling with a 1/8 twist rate and M4 feedramps. As with all BCM barrels it is proofed (HPT) and magnetic particle inspected (MPI). To give the shooter the best balance of weight and accuracy this BCM Recce barrel has a mid weight profile and a mid length gas system. (410 stainless is a harder and more corrosion resistant than the conventional 416 stainless found in most barrels.)
