I haven't shot one since '87 (M16), so its been a LONG time. He's never shot one. I want one REAL bad. But I don't know much about them. I don't want to spend a fortune on it, nothing from Les Baer. So I'm trying to find a nice, decent rig that will be dependable/reliable, and I can upgrade over time. I'm not sure which brand or caliber to go with. Several have told me to go with something larger than the .223, but I don't know what the drawbacks would be. I'm sure it will limit the interchange of parts, but that may not be a real issue.
I want one with the quad-rail, A3 flat-top with removable handle, 6-position stock, some type of optics, backup iron sights, etc. I probably won't get all of that stuff to start with, but would like a good foundation to build on.
I don't know which brands to consider. I've heard good things about Rock River and Bushmaster, but I still know VERY little about all of this.
