Got my barreled receiver back from Tim Schufflin in record time. The fit of my Berretta gas cylinder to the Criterion barrel was perfect so no Locktite bearing fit green was needed this time. Fit the hand guard and lower band(still screwed and glued) to the barrel with the green Locktite and Shogoo,just can't help myself on that. I found that the stock ferrule and lower band fit was terribly tight, perhaps variances in manufacture caused this. I bent the U on the stock ferrule a bit downward and ground clearance on the lower band.I started to and maybe should have removed the stock ferrule and lowered it but it's screw is peened to the point of having to ruin it to remove it so I choose this method, I can always buy the necessary parts and try it the other way if needed. This poor shopped picture is not my lower band but one I found online and edited to show where I had to Dremel. Now I have good pull down .Also removed wood from the bottom of the lower hand guard and Shogooed it to the barrel.Now there is a minimum of 1/8" clearance between the butt stock and the lower hand guard. Overall I am pleased with the project thus far and if it will ever stop raining a range report is coming .
