Inside diameter was too small! (05/06/2016)

I purchased this Badger Ordnance MK12 .750 gas black from Brownells and when the customer tried to install it on his barrel, it would not fit due to the fact that the inside diameter was too small, I also tried just to make sure and it was too small and rather than try to file and sand (which we should not have to do, since it is supposed to fit any .750 gas shoulder) the inside so it will fit, I sent it back and sold the customer a titanium gas block which fit perfectly!

Could be that I just received a bad one but why take a chance on another one and the hassle of having to send it back also, if it turns out bad, like the first one!

Perfect for your MK12 clone (07/09/2016)

I've installed a few of the Badger MK12 gas blocks with no issues.

Clone correct (19/07/2018)

This gas block is correct for your MK12 Mod 1 clone builds. It looks great and works great! But be aware it will most likely be a tight fit to your barrel, and the instructions even say it should be a press fit. This doesn't mean it won't fit, just that it is meant to keep close, tight tolerances.

You will need your A game on this one! (18/09/2018)

This gas block is a legit piece of kit. If the 1 star review had read the directions he would have discovered that badger states this is a press on fit. I used this on my MK12 project and had no issues. Reading the directions prior to install allowed me to get it in place without any fuss. It is tight and it will need heat to be removed though. The one I received included a stainless looking roll pin for the gas tube.
