How did anyone with the Green Mountain 14.5" chrome moly steel barrel who welded on the Cutts compensator re-blue it? I'm cheap and don't want to take it to a gunsmith (but I might), I'm a do-it-yourselfer. I have the blued Auto Ordnance 1927A1 T1. Where and what kind (cold or hot) and brand of blueing? Where'd you purchase it? And as far as welding on of the Cutts compensator, how do you weld it to the barrel without buldging it or damaging it? Thanks.
