I have the 18.5" MVP..it's awesome...I can shoot 300 +\- yards and hit bullseye triple tap...did it twice...I put a Leupold mark ar 3-9x40 mil-Dot...(I don't shoot sitting or standing! I get on the ground ... Lay on my tummy and focus on my breathing, check my mil-dot twice n pull!
My MVP has only been out 3 times...as what Cadre says...it doesn't like pmags...I have to disagree...never had a problem with my Pmags using either .223/5.56 NATO (got 5 different pmags for'em)...no issues, yet! (Maybe, becoz I have an 18.5"?)
I wish I could take it out, but too many side activities going on for the holidays!
