LOWER PRICE I got a Choate 4 shot Mag Ext for Christmas for my Rem 870 12 ga. Only problem is it's the wrong one. I need the 3 shot. Before I go thru the hassle of trying to exchange it with Brownells, I wanted to see if anyone would trade me straight up for a 3 shot extension or just buy it from me. I'd sell it for $40.00 which is $8.00 under Brownell's cost and you wouldn't have to pay freight. Any takers?
