Failure to eject/ bolt stuck

[A5BLASTER]

The adj. GB you have has a hole in the top to be able to properly aline it over the gas hole of the barrel, a feature I really like,can't remember the drill bit I use but it works perfectly by putting bit shank thru top of block into barrel gas hole then tighten down. After installing GB I then install gas tube. Hope this helps.

When did wojetk start putting that in their gas blocks? I have 3 of their adjustable gas blocks and none of mine have that.

Newest one is probably 6 to 8 months old now.
