    1. AR15 Gas key

      Customer service is great. Part quality including finish is very good. Perfect fit and function. Can’t wait to purchase a BCG. on 11th Jun 2020

    2. Im a believer now

      Ive owned nitride, ive owned parkerized, i even have NP3, none are as slick as the Mystic black. Ive had some recent bad service from another company for whom shall remain nameless(at this point who they are doesnt matter anyways). While This other company had more of my money, they seemed to think my value as a customer was minimal i suppose. Cryptic however sent my order out immediately(just a bag of gas keys i was intrigued by) and i received this order in 3 business days. The packing was perfect, double bubble wrapped. The contents were in perfect condition, gas keys were slightly oiled and a FREE STICKER!(which wasnt covered in oil;) Slick is the best description of the surface, even after cleaning the oil off. Every gas key was perfectly matching, no machining marks, as if someone was picking only the best gas keys out of the bin. I have six bcg’s currently, of two different manufacturers, every gas key is slightly different. Ill be happy to be replacing them with these new pieces from Cryptic. on 20th Jan 2020
