BCG shipped fast and came packaged very well, pre-oiled and ready to go. First day at the range I ran a couple hundred rounds of both brass and steel without a hiccup. Cleanup was as simple as wiping it down with the microfiber cloth they provided. This is an excellent BCG from a top notch company with excellent customer service. I will be ordering from them again for my next build. Thanks Cryptic! Michael A on 20th Sep 2020
