I have a Rossi .223 Varmiter heavy barrel,very,very accurate can shoot the hell out of a playing card at 200 yds.Now with that said,I donot like the forarm atached to the barrel with the same screw as the sling.If you mess with this swivle stud it will throw your accruacy.I tightend the $hit out of mine,locktight and all.
But for $199.99 w/4-12x40mm Tasco World class Pluss scope,rings and bases,pluss case and 410 barell I'm happy.
