This is probably way too late but...
It struck me as I read through the comments about this product that the spacing problem could be cured by threading a nut on the threads of the barrel, then the backing washer, then the compensator. That way, you can screw the nut in or out to orient the comp anywhere you like and you dont have to have a smith cut off the end of the barrel and recrown. Just my thoughts and if someone contacted the manufacturer about the problem, they would probably be happy to throw a matching nut in the package with the comp.
Almost perfect
This was purchased, primarily for aestectics, to replace the factory Mini-14 style cast iron muzzle brake included on my Ruger 10/22 "Tactical" carbine. The quality is top notch... and this thing is just perfect for a Browning Buckmark or Ruger 22/45 Lite with a threaded barrel, but as for my tacticool 10/22... ... unfortunately the female threading on this brake is about 1/4" too shallow, so that when it is fully threaded onto the barrel of my 10/22, there is a 1/8" gap between the rear of the brake and the factory muzzle brake washer. Remove the washer and the gap becomes almost 1/4" from brake to barrel step. Disappointing, though not the fault of TacSol or the brake itself, still very cool and perfect quality, and well worth the money, just realize it seems more intended for threaded pistol barrels, and may dissapoint you on the Ruger factory threaded barrels. I may have the barrel/threads shortened and re-crowned, if it doesn't cost too much more $$.
Pretty Piece / A Bit Uneccessary
I bought this to go along with my Tactical Solutions bull barrel. It threads on easily and looks nice. Doesn't really seem to compensate for much, it is a .22 after all. It does vibrate loose, so a drop or two of loctite is needed. It looks good, adds a little something to my customized 10/22, but does little to nothing as far as compensating. But then, I bought it more for looks than functionality anyway!
