BCM 18" SPR Mk12 SS410 Rifle Barrel, Ionbond Black

Description

Requires the use of the .750 gas block
Approximate Weight: 2lbs 8oz.

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.)

DLC Coating stands for diamond-lkike carbon coating, and is a nanocomposite coating that has unique properties of natural diamond low friction, high hardness, and high corrosion resistance.

DLC 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

DLC 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 DLC finishes, absorb oil and release it over time due to the unique characteristics.

Requires the use of the .750 gas block.

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

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!

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!

top notch quality

Posted by Smooth on Sep 22nd 2016

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.
