BLACK NITRIDE

Black Nitride is a process commonly referred to as SBN (Salt bath nitride) and QPQ (quench polish quench). These are a form of nitrocarburizing or a Thermo Chemical treatment that improves wear resistance and corrosion resistance of ferrous metals with little or no dimensional change which causes the hardening of steel. The chemical bath results in a deep dark black with a harder, more durable finish.

    Tool Craft Nitrided 5.56 BCG

    Posted by Don R., Lakeland FL on Jul 4th 2018

    I purchased this BCG as it is my first Tool Craft BCG and have read many favorable reviews on the Tool Craft BCG's. I will be ordering more. It is very important to have a good supply of BCG and other critical parts as spares. My order from E-Arms shipped quickly and it is being fitted to a PSA upper. I expect it will perform flawlessly.

    Toolcraft BCG Review

    Posted by Brandon on Jul 4th 2018

    In life, there are 3 certainties. Death, taxes, and having a quality experience when ordering from Greg at E-Arms. Greg consistently delivers a quality product and ships fast! The Toolcraft BCG is a great option for a new build or a replacement BCG in your rifle.

    I built an AR-15 pistol with 10.5" barrel. It did fine with good ammo but would sometimes fail to chamber the next round when using steel ammo. I put this nitride BCG in place of the phosphate one and now the "pistol" cycles steel as well and brass ammo.

    Outstanding BCG!

    Posted by Kenneth on Jun 22nd 2018

    Looks and functions great. Was really impressed with the quality and finish. Only put 20 rounds through my new pistol build to test the gun and it ran great with this BCG. Would definitely buy another when I'm in the market for another. Price is great and ordering was easy and got it in a few days.

    Ordered 2 BCGs. Fast shipping. Excellent company

    Very good quality BCG. I put Mcfarland 1 piece gas ring in all of my BCGs for reliability. E-arms is awesome. The last one i ordered, USPS lost it in transit, which sucked cause i still got packaging with nothing in it. I was pissed off. Delayed my build. E-arms took care of it fast. I knew then that E-arms was a good choice. Im proud to have there stickers on my tool box at work and have told others about there deals and customer service. Thank you E-arms. Toolcraft BCG is the only way to go.

    Toolcraft nitride BCG 5.56

    Posted by AZHTfreak on Jun 5th 2018

    My goto for ALL builds - a complete, total no-brainer - actually prefer the 9310 over the C-158 bolt. Newer, more advanced metallurgy... I do NOT get the fanboy $300-$400 depleted Uranium Rhinoceros Foreskin BCGs - why burn $$$?

    Great

    Mine came came in today and I am blown away with the quality of this BCG. Vendor is super fast and tool craft makes some awesome stuff. If your thinking of buying a new BCG I would strongly suggest this one.
