Paul, the maker says it Fits: - Plain Barrel Mossberg 500/590 12 Gauge models only - Note: This heat shield will not fit the 835, 590A1 series, or any version shotgun with Ghost Ring Sights. (It's probably possible but would void any warranty or return possibility).

no it will not fit Fits: - Plain Barrel Mossberg 500/590 *****12 Gauge models only -

J.G. you the man as always! That is what I wanted to here the return and warranty bit! So, I think I'll try two after I get a reply from Mossberg on making things for the far superior velocity shotgun (410)... Really, check the specs^__^ Use a FMJ-AP slug- 3" super magnum(I make them$$$$) 55yds and under No, body armor gonna stop it!(so, far! But, just donated OLD surplus body amours)!
