an, I've messed wit that thing so many time it makes me sick. I have a cheap little Double Star Star-15 rifle. It's pretty basic but I like it like that. I sometimes think about getting another upper to change things up a little but as is it's a pretty accurate rifle. Plus it's light and even my broke down old man self can pack it around a pretty long while if need be. Boy even my little M4gery is getting expensive. I got mine before the rush was on and spent about 700.00. Last I seen on gunbroker a double star upper like mine was over 700.00. I'd sure like to get a bunch more ammo for it. Way things are going I hate to use any ammo I can't reload easily. The last 500 rounds I got cost me 100.00..whew.
