I returned several items including this one unopened 2 weeks ago and no response. I wrote them . No response.They are not answering the phone. I will keep you posted.

Shipping was very fast and product looks well made, and performs as to be expected thank you

excellent fit and finish, the set screws are bulky and very course thread, worked perfect on my Ballistic advantage dimpled barrel. the febon gas tube cobratac sells fit perfectly very happy

Nice gas block but this is not the one they sent me. Mine is open on the end and no cool cobra. Very light and 2set screws. Not yet mounted awaiting a new barrel Cobratac Response: We no longer laser mark our gas blocks due to many people complaining about having markings on their firearm... but it is our same great quality gas block at an affordable price!

Used with Cobra Tac Systems rail. Easy to install using the two set screws.

looks great and works perfect roll pin was tight but that is how it's supposed to be and came with roll pin highly recommend and happy with my order.

Nice low profile gas block with set screw. Bolted up nice and tight along with good alignment for the gas tube and roll pin.

Fit n finish are perfect

the roll pin isnt supposed to fit easy, you need a punch set and some skill to install them... Please go see a qualified armorer...
