Very cool. I didn't know you could store two pistols in the butt stock, too. :laugh:
Oh, BTW, mine were both Charter Arms guns as is the Explorer. Here's how I had the one I sold my SIL set up. I took the scope off it as I like that scope, sold him the rest. I tacticooled it just for fun.
That one was 15 rounds with a large spring taking up a good part of the magazine. I had to bend on the front part, the "ramp" to get it to feed reliably. I had 25 round Ramline mags back in the day, worked fine for a while, but were plastic and kinda fell apart. They were bent banana style to feed properly.
There used to be a lot of AR7 aftermarket out there, but not so much anymore.
