Guys I have a Mossberg MVP Predator, early model with a 20" "sporter" style barrel. I have a couple things to state. First off the rifle is a tack driver, especially for a guy like myself that gets sub MOA at 200 yards and uses factory ammo (have not the space yet to get into reloading). I probably have close to 800 rounds through the gun and currently has a Redfield 3-9x 40mm Revolution scope. I should have gone 4-12 but eh perhaps later. The gun is INCREDIBLY accurate. One thing I was considering though, and I dont know if its possible through Mossberg is to change to a 24" med. bull barrel. I want to thread on a flash hider and my barrel did not come threaded. It also is the thinner profile sporter model. BUT I MUST SAY THIS: "and this is pretty much amazing in my reasoning) but the MVP 5.56 sporter barrel is actually THICKER than the barrels on my Savage 110 in .30-06 AND my WWII Mauser 98K. The sporter barrel is a full 1/8th of an inch thicker at the crown than the barrels on my .30 cal. and 8mm! So it brings me back to my circular reasoning, do I actually NEED a med. bull barrel? I see all MVP models now have them, and none except for the FLEX (last I checked) still had a sporter barrel available. I called Mossberg and they said they do not sell barrels nor do they do barrel swaps even on their own rifles. That struck me as odd and Mossberg's customer service is not the most knowledgeable regarding their own products as I have come to find out so maybe it is possible? Should I even bother messing with it just to get a bit of a thicker barrel? I do prefer a heavier gun rather than a lightweight rifle, it helps me with accuracy. Your thoughts?
