Ratings & Reviews
I ordered one for a build for my wife. Seems to be of high quality. The staking on the gas key is all uniform and looks good. The only thing I would warn of is the colors on the bcg I received had a lot more blues and greens as opposed to the pinks and purples shown in the picture. Works out fine for me as it's in a robins egg blue cerakoted upper and actually matches pretty well.
