Bloop tube Question

[Tanktrek]

I recently purchase a bloop tube from Bill Earnest (ESP). When I initially mounted the tube I had excellent results. But recently I have been having trouble centering the tube and it is difficult to get my windage settings correct.

The tube has a notch in the back that I try to align each time I mount it.

Any help would be appreciated.

I also have a Earnest bloop tube. What you need to do is put a guide pin in the a hole at the end of the barrel. Mine is a screw that has the head removed. This will ensure proper alignment. Very happy with mine.

Thanks bugman

I was considering that very thing.

Bill Earnest should have supplied one with the tube.
