FYI guys, I tried swapping my grizzly barrel onto a Rem 870 and it worked fine, slipped right on...The "problem" came in when I tried putting the Rem 870 barrel onto my grizzly, it was too tight and I didn't want to "force it", so...Obviously the tolerances are a little different, but maybe it's just a matter of fit and function from the factory?* By this I mean, maybe at the factory there are barrels and receivers that do the same thing and they just put ones together that "fit"...* Anyone else agree?CheersJay
