Outstanding machined and very smooth BCG with very good looking peened bolts. Fits perfectly in my AR and I have no doubt it will perform flawlessly. This is my second purchased carrier from Cryptic Coatings and will not be my last. RB on 30th May 2017
A friend and I decIded to get the Bronze and Gold. We figured we'd choose once they arrived after anticipating their arrival like waiting for Christmas morning. They're amazing.
Perfect fit; Beautiful Finish; Easy to clean; Flawless, smooth feel to it. Our AR's loved them.
Will be back when I get another rifle. Maybe Father's Day? 4th of July? Birthday? JuanR on 30th May 2017
I placed my order for the Mystic Gold (I like gooollldd!) BCG on Sunday night. Order was processed and shipped out on Monday via USPS. I got it midday on Thursday. Very impressed with the prompt shipping. I will definitely be ordering my next BCG from this company. Mike on 25th May 2017
Got my Mystic Bronze BCG the other day for my high end AR build and couldn't be happier with the fit and finish! Sits great in the rifle and the BCG is slicker than snot, cant wait to start running rounds through this little guy! Add that with the super fast delivery, very awesome product. Drew on 23rd May 2017
I went to order the mystic gold 5.56 BCG, said it was unavailable. I sent an email to crypic and they got back to me quick, told me that they'll contact me as soon as it becomes available again, next day it was available! I ordered that bad boy and although the weekend interfered with a retardedly fast delivery, it was still here pretty quick(3-4 days) I'm very pleased with this product and will do business with them again in the future, although I doubt I'll have to ever buy another bolt, unless i decide I want another AR...but if I do, I'll be back for another one here.
