MOSSBERG 500 SGA BUTTSTOCK & M-LOK FOREND KIT

MOSSBERG 500 SGA BUTTSTOCK & M-LOK FOREND KIT Reviews & Ratings

The SGA is an adaptable stock for the Mossberg 500/590/590A1 12 gauge shotguns, designed with a wide range of customizable features and accessories to meet individual end-user needs. The M-LOK Forend is a simple, lightweight forend for 500/590/590A1 12 gauge shotguns with 7-3/4" action tube assemblies, designed to provide much-needed adaptability with the attachment of optional M-LOK accessories and mounts. NOTE: The Mossberg forend in the sets will NOT fit the Mossberg 500 with 6-1/2" action tube assembly or the Maverick or current production Mossberg 500 synthetic with pinned-in action tube assembly without replacing with the 7-3/4" action tube assembly.

Great Quality, Fast Shipping
Forend took a bit of finessing to fit on 6 3/4 Slide Assembly on my Mossberg 500. Definitely a great upgrade. Same stock shape as my Hunter Stock on my deer rifle. Thanks for yet another great experience Brownells.
