I own a Charter Amrs AR-7, and it has been bounced around by myself and other family members for years. My one grumble with it that the stock is a fairly soft plastic, so it picks up a lot of scratches and scuffs if it isn't protected. Also, I think they could have put two magazines in there, but it might have made the floatability iffy.

I like Russian subsonic match for it for really small game. I have a couple of spare mags, and the one with a white band painted on it is loaded with cold ones, while the others are loaded with the most cost efficent high (not hyper) velocity hollowpoints that are on the shelf when I need to buy more.

One thing I am thinking of doing is epoxying a small nub onto the underside of the stock so I can wrap a length of webbing around it and not have it slide forward under tension, then maybe add a small pouch to the side. I already put a tiny dot of white enamel on the front sight, and a matching half ring to the rear, for speed.
