The blem on these blocks is that some outright donkey didn’t read my print and undersized the holes for the screw heads so custom screws had to be machined for them. The black nitride finishing might have some pitting in it. Other than those two items, there is nothing else wrong with them and they are absolutely sound mechanically.

Bought a rail but need a good gas block? Look no further! Weighing in at 1.3oz, this .625 gas block is fully adjustable via a screw in the front and lockable via a screw in the side. This block is attached to your barrel by compression which is attained by tightening the three screws on the bottom. It is suggested that a REMOVABLE thread locker of your choice be used on the screws. Each gas block comes with a roll pin as well.


-Black Nitride finish
-Gas port witness hole for effortless gas port alignment.
-Gas tube removal hole for gas tube removal.
