Being a Mossberg fan myself, a well priced 590A1 clone would be my first pick. Preference is to the 20" barrel, 8+1 capacity model. Ghost rings, bayonet mount... if you include a good quality M9 bayonet copy, you can put me on the pre-order list right now.
not specifically singling this one suggestion out, but it seems silly to me to clone something that already exists on the Canadian market, and is extremely easy and affordable to obtain.
if youre going to make something, either make it in a configuration that is simply unavailable to Canadians, or make a clone of a $2000 rifle that is out of reach for the average Joe's plinking budget.
perfect examples of these are the 8.5-12.5" Grizzlies - while 870s are readily and cheaply available, they are not in such short barrel lengths. the closest you can come to this is by using a Dlask barrel. the 870 Express is actually lower quality than the Grizzly, and would still cost 2x as much. if you up the receiver to an 870P, youll end up with a better gun but at 3x the price.
another example is the M305. Springfield M1As were well out of most peoples price range, the M305 made them easily accessible to everyone.
IMO it would be a poor idea to clone something like a Mossberg 590, just to come in at $100 lower price. very few people would buy them. a lot of the suggestions here are in the same vein - asking to clone something just to make it $100 cheaper.
i second this idea (or something similar):
make them in .22 hornet, .22 WMR or .22 LR, but slightly update the design with 16" barrels and an integrated receiver rail. there is a huge market for an accessible, bombproof 'survival' firearm. the Henry AR7 and Marlin Papoose are overpriced and crap (sorry owners, its true).
id also love a
modern pistol in 7.62x25mm.
