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.)

 

• reduced coefficient of friction

• increased abrasive wear resistance

• antiscuffing/antigalling

• high fretting resistance

• high pitting resistance

• resistance to corrosion and hydrocarbon fuels

• high integrity of surface structure

• good adhesion to base materials

 

IonBond coatings directly improve wear resistance due to their high hardness, low coefficient of friction and high structural integrity. These coatings with thicknesses of only a few microns and with hardness up to 4000HV, result in increased firearm life and functionality. The IonBonded finishes, absorb oil and release it over time due to the unique characteristics.

 

Requires the use of the .750 gas block.
