Thread: prednisone & stomach bloating. prednisone & stomach bloating Just curious, do a lot of other people on prednisone struggle with the bloated belly side effect? I seem to be really gassy (from both ends =x) and my stomach always looks like I'm about three months pregnant.
DPMS marks their barrels .223, though they actually have 5.56 chambers. Olympic Arms marks their barrels with 556, with some additionally marked SS or SUM. This marking is used on all barrels, even older barrels that used .223 chambers and current target models that also use .223 chambers.
I can't really compare the two, as I haven't shot the AR Stoner barrel. Having shot the DPMS barrel alongside many other mid to high end barrels though, I have yet to see anything that offers a significant advantage over the MK12 barrel in terms of accuracy or reliability.
