Maybe a clamping feed tube, but the o-ring one works pretty well.
Strengths:
Simplest closed bolt gun in the world. No one else can even come close.
Weaknesses:
You can't be an idiot. You might even have to be able to read.
Review:
Much faster than the original Omen.
Much easier to tune to the recock.
Works great with a Halo, especially one with a Victory Board.
The new LPC allows it to work at lower pressure.
The gauge allows you to monitor that pressure.
Feed tube is super low and works as well as a clamping feed tube.
Now says Evil on the side so everyone doesn't ask what it is.
Check out the new Omen triggers too.
Conclusion:
Buy it. You'll have a great closed bolt gun at a super cheap price.
