This BCG is heaven for lefties. I have a black rain ordinance bcg too, but the gas key of the bcg chipped on that one and black rain ordinance didn’t even respond. Not that it affects the function but l wanted to put it out there. On the other hand cryptic BCG is unparalleled for a leftie or a rightie. I have fed it the most ridiculous cheap ammo and various grains-in many thousands-, it didn’t even cough. I am a customer for life.

I purchased this late 2023, the one I received is mostly brown and is very disappointing in comparison to the picture. The product functions extremely well, but looks nothing like this picture. I have reached out to cryptic coatings and they are improving the coating and willing to replace mine directly but the one I'm supposed to receive still is very disappointing. By the end of 2024 it sounds like they'll have it together. All of the other colors are phenomenal just not this dragons breath. I have the gold and the bronze version and they are beautiful.

Very slick coating, paired with a Geissele platform. No complaints thus far. Going to get the midnight black bolt next.
