    Great bolt at a great price

    Was asking around for a recommendation on a quality budget BCG and a friend said he had great luck with a Toolcraft so I decided to give it a try. Working great so far!

    Great BCG at a really good price. E-arms was super fast with shipping and nice communication emails throughout the process. Will definitely be one of my first stops when buying in the future.

    Awesome BCG, Awesome vendor

    Posted by Chip on Apr 19th 2018

    This was my first purchase from E-Arms. I grabbed one of these on the $72 sale, the nitride coating and build quality are excellent. E-Arms sent the next day I believe. Great prices, great shipping, what else is there to say? I'll be a repeat customer.

    Nice BCG

    Posted by Jerry Golden on Apr 10th 2018

    Very fast shipping. Didn't expect the quality to be so high on a BCG at this price point. I always like to feel the smoothness at first before disassembling and lubricating inside and out. The fit is better than some I have paid over $100 for. Bought as backup but now plan to use in place of one of my others. Nitriding is excellent. Completely satisfied.

    This bcc is awesome. Looks like it is a quality built BCG. Slid right in to my upper and works perfectly. Great bang for the buck!
