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 system October 27, 2017
Reviewer: stephen horning from Olympia, WA United States  
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 October 27, 2017
Reviewer: John Peeler from Covington, TN United States  
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

Reviewer: Mike W  
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.

Ammo finicky! September 22, 2016
Reviewer: Justin  
For the price im a little bummed. This barrel is only a small margin more accurate than a Daniel Defense, lightweight, chrome lined 16" middy non-free floated upper I built at the same time. This setup is free floated, hand lapped stainless, it should SMOKE the chrome lined barrel. Its nice, but not $369 nice!
