BNIB Mossberg 590 Retrograde 18.5"

Selling a brand new, never fired, Mossberg 590 Retrograde 18.5" 12 Gauge. I bought it online and the description said it had a bayonet lug, but it turns out that is only on the 20" models. It's a beautiful shotgun and I thought about keeping it but I've decided I want to ultimately get the 590A1 Retrograde. Bought it on sale $70 off, selling it for $900 even, shipping included. Cable lock and manual included. E transfer and PAL required.
