    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!

    Solid Product

    Posted by Fred Woodbridge on Feb 27th 2018

    I was able to buy this at a great price (as always) from e-arms and I am highly impressed with the manufacturing quality. It matches the Odin Works nitride BCG I paid almost double for! The staking on the gas key isn't as deep as I'd like, but it is adequate. Everything looks to be very securely attached, nothing loose. Every surface is sheeny, no tool or machining marks are evident. From the looks of it, I don't think the gas key is chrome lined, but I wonder if that's necessary with the nitride treatment. The bolt looks incredible, and I think this will only be even better with time and shooting.
