Purchased 2 mystic blue bcgs and both of them are black Not blue their customer service is great They confirmed the first bcg was indeed Mystic black so I chose to keep it second time received a black bcg again it is definitely slick and shiny just wanted something with color since blue is one of my favorite colors Disappointing Jason on 20th Aug 2020
This BCG is so nice i want to wear it on a chain! Runs super smooth and easily wipes clean with a rag, far easier than even my other nickel boron BCG. No more disassembling, soaking and scrubbing after everytime i want to go shoot.
Cant wait to get the lightweight one in the black coating for my lightweight 2 gun comp rifle. Hands down the nicest BCG on the market! Just wish i could afford one for every rifle. Cody M. on 15th Aug 2020
If I could give this 10 stars I would! Far superior than any other BCG I have felt or shot. Fires flawlessly and can basically be cleaned by the wipe of a towel. So impressed I’m about to order another 9mm BCG. Loren Card on 10th Aug 2020
