If you just want to shoot at people breaking into your house get a mossberg 500 or a Remington 870…
I’m sure you can rice them out with a pistol grip and other things so you won’t be able to shoot shit with it lol
Both excellent shottys. 
Another nice shotty fairly cheap is the Mossy 930/930SPX. Semi auto and lightweight. No straight up pistol grip conversion though…I guess there’s a recoil spring in the stock. 8/
LOL @ some of the shotty’s above all pimped out. Especially…
Stoeger double defense!!!
EW. my buddy wants that and i think its terrible.
i have this on the way
i had a depositt on a S&W m&p15 but the rock river has a wayyyyy better value to it. more bang for your buck 
My friend bought one of those Stoeger’s and I like you don’t care for it.
Who you using for an FFL on the RRA? That does seem like a pretty good deal though I prefer my buys FTF ideally.

Just thought of this…what about NY compliance? Will they ship here considering there is a bayo lug etc?
