Works! The coating used on it is nit great quality, had to bkue a couple areas that showes little to no sign of color
This is a really nice gas block and it works well. The gas block for the money spent is a great buy and I would purchase again . Thanks
Nice tight fit. Quick shipment. Cobratac makes some bitchin products, don't buy anywhere else, these guys are legit!
Nice gas block for the price. Fit and ease of which the roll pin went in was great. Finish could be better. Thus the 4 stars.
I've been a prior customer of Cobratac. Bought this for a build but made a mistake on the size. Requested to cancel within 24 hours. Watched the order sit for another 2 days then ship. My order cancellation request went unanswered until after it was shipped. Was told I would have to pay for return shipping. Will I buy the correct size gas block from Cobratac - no. Because when I buy something I can't get the order cancelled and changed before it ships. I don't have this problem with other merchants. I just went through an order cancellation with a merchant on Amazon yesterday. They responded and canceled my order even when I told them I found the same item at half their price. What rating did I give them - 5 stars. I'm a retired CIO with (40 years IT) back office e-commerce background. Online transaction order cancellation was common practice BACK IN 1997. Need some help folks?
The fit was a little tight but with a little emery cloth the fit was perfect.
