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
anti-scuffing/anti-galling
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.

    BCM® 18" SS410 Barrel with Rifle Length Gas (stripped) 1/8 Twist (Ionbond BLACK

    I’m still in my initial testing of loads to find out what bullet, weigh, powder, etc. this barrel likes. To my surprise it likes a wide range bullet weighs and powder. With less 150 rounds through this barrel, I have already found 3 different loads that will give me MOA to sub-MOA accuracy.

    MK12

    I couldn’t find a single site that had an upper receiver. I’m glad Bravo Company has all the parts available to build my own. 90% of my parts will definitely be coming from here. I’d recommend 10/10

    Amazing Barrel

    I used this barrel (along with a BCM Upper, M-Lok Rail, BCG, and Grip) to build a MK12. It shoots much better than I do, and I highly recommend it for anyone wanting to build either an SPR or 3-Gun AR.

    BCM 18" SS410 Barrel with rifle length gas system

    Absolutely phenomenal barrel. Easy to install and no issues setting up the gas system. I took it out and fired 3 rounds through the same hole at 25 meters to get a zero. Definitely a 1 MOA or less barrel. I recommend this barrel for anyone interested in 3 gun or a Mark 12 set up. Best barrel I have ever shot on an AR 15 by far. Hats off to BCM.

    18" rifle length barrel

    Excellent product. This is my first rifle to build from the ground up. Assembly was easy, and it was nice to not have to worry about the quality of the barrel/material. Shoots true, and is perfect for coyote eradication purposes

    Bcm is always high quality

    Haven't completed my build yet due to expenses, however the visual build quality is outstanding. High polished feed ramps that match up perfectly to my upper reciever.
