BCM® SS410 Barrels
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. To give the shooter the best balance of weight and accuracy this BCM Mk12 barrel has a mid-weight profile and a rifle length gas system. (410 stainless is a harder and more corrosion resistant than the conventional 416 stainless found in most barrels.)
Ionbond PVD coatings advantages
reduced coefficient of friction
increased abrasive wear resistance
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.

    top notch quality

    I haven't installed the barrel yet so this review cannot speak on the accuracy of the barrel but out of the box the barrel looks extremely well built. I mocked it up in a BCM stripped upper and have a PRI gas block with the pop up sight as I plan to build a MK12 Mod 0 clone. Everthing has fit together masterfully this far. The inside of the chamber and throat of this barrel are the best I have seen thus far. I am super excited to get this build completed and learn the accuracy potential of this barrel.

    Have not installed it yet but it's pretty and fits really snug and tight in my Vltor MUR. The MUR and BCM KMR ALPHA 13 are getting cerakoted. Will post a range review when it's all done. BCM makes good stuff, don't foresee any issues with this barrel.

    BCM 18" Ionbond Black Barrel

    Posted by anonymous on Nov 18th 2012

    This is the best barrel I've ever owned, including Noveske! I built up a Mk12 Mod 0 Rifle using this barrel and BH 75 gr and 77 gr ammo. On paper it shoots .5 MOA at 200 meters and hit steel ram silhouettes at 500 meters (546 yds.) every time with ease. Even knocked off 2 half-sized rams and a grouse silhouette at the same distance. This barrel is awesome. I couldn't be happier!

    Shoots lights out with Black Hills 75gr. BTHP ammo. Very pleased with this barrel.
