Thanks for the comments guys.
Well it rained cats and dogs yesterday... so much for trying out the barrel. Guess I need to rely on some test shooting. But I don't have a catch blanket set up yet. Soon though, very soon.
It worked well enough that I'm going to go ahead with the same mod on my two SL68's and the Ranger. The beauty with those is that they are one barrel go one body so I can mark and put the slot at the top of the barrel so there isn't any chance of any side spins. Same with the SL's since they are just a slip in and clamp setup. It'll be sweet to not get any double feeds or rollouts with follow on blank shots.
I had a "Paintball God" moment once.
Like Al Bundy's Polk High football moment I live on
for the slim chance of repeating that one time
miracle in some small way.........
