Excellent small profile gas block!

by -

Tight lock up on BCA 20" barrel(which had one set screw dimple already in it) creating perfect gas port alignment. Used the Expo arms gas tube that came with roll pin. This block included a roll pin, but not sure what it's supposed to fit as the roll pin included with gas block was small and easily drops through roll pin hole in gas block and gas tube. However, roll pin included with gas tube was correct size, so no issue for me.
<br>Finish is good, machining is excellent.

Perfect fit for my carbine length barrel. Nice finish and snug fit
