You can get a new AK for $300 or a surplus AR-15 for $500-600 in most pawn shops. The AK ammo is cheap in bulk and you have very wide availability
with the AR-15 and it's ammo is pretty cheap too when compared with 7.62 NATO or.30'06. In the unlikely event that you'd be in pitched gun
battle, either gun is far superior to any hunting rifle in terms of manageability and magazine capacity with the SKS being a decent subsitute .
The Mossberg Defender is ok but the Remington 870 is much more common and there's tons of aftermarket parts for it. You can find them used for as
little as $150 in just about any pawn or gunshop. It take about 5 minutes to switch from your wingshooting or rifled slug barrel back to a home
defense barrel. I prefer the 20" barrel over the 18" barrel because it give you a better sight radius and tighter shot pattern.
