ROUGH CUT Modified 590A1  Heat Shield to fit the Mossberg A1 HEAVY-BARREL Mossy Shotgun


Its a BEAUTIFUL DAY in the pump-shotgun world!  We now have modified heat shields to fit the Mossberg 590A1.  These are hand-fit on our in-house 590A1 to fit the dimensions of the Mossberg A1 Heavy-barrel.  


Our design modifies the brackets and inner-rings for geometry reasons.  Shield will hide about 90% of your standard brass bead, but blade sights are perfectly visible.   All hardware and brackets are included (Will include 2 sets of zinc-black screws in 8mm and 12mm length). There will be a small 1-2mm gap between the brackets (This is normal, and dont over-tighten).  See the included photo of the ONE model (Short 7rd mag-tube) where this shield will NOT work.  This a 'rough-cut' modification, so its not going to be 100% free of burrs or sanding marks, but we will keep the price reasonable on the labor costs.  As usual, all our shields are warrantied FOR LIFE! You break it, lose it, or throw it off a CLIFF......we will replace it for LIFE.

Remember, this is a prototype, and if you dont like it, shoot us a ring.  We are NICE GUYS!
