I have a Colt a2 Sporter II and I am very curious on if this is a pre or post ban AR?
I do not know that much about what that means but I hear it used a lot. Also, does anyone know if I can put a new upper on it such as a DPMS upper? I really want to get a 1 in 9" bull barrel rather than the 1 in 7" that is on there. I know there is some talk about Colt's pins being bigger but I do not really understand all of that. Thanks guys!
since the ban was allowed to sunset, it doesn't really matter. yes you can put any upper on it you decide to get, ya just need to know what you have so you can get offset pins or whatever ya need. If you looking at 223 uppers, I'd go with an 8 twist, I have them in 8,9,10, and 12 twist and the 8 is by far my fave!RR
RR beat me to it... Pre and post ban doesn't mean anything anymore, and the off-set pins to mate the old colt lowers to new uppers (not sure if new colt receivers are still bigger screws, but my old colt lower needs offset screws). Alternatively, older colt uppers require a bushing to be mate up with non-old colt lowers.
All that said, it sounds like you're really just looking to re-barrel your rifle, not that you're looking for a quick change rifle. A new upper will run between $450-800, while a new barrel can be had for $175-300 and changed out either by you or a good buddy with a little more experience in about an hour (or 20min once you get used to it). Get a set of go/no-go gauges and double check the headspacing and you're good to go. A gunsmith will rebarrel an AR for about $60 around here, so that's another option, $250 is a lot cheaper than $600...
Oh wow, yeah that would be nice! except for the fact that i really want a flat top since mine has the carry handle, so that kind of stinks. It would be nice to have that. What do you guys think? Is it hard to get ahold of some offset pins?
Here's a stripped receiver also... re-use all of your other internal parts from the old upper, slap on the new barrel, and you're good to go. Probably take you about 5hrs to do the rebuild if you get a book to follow along with. I can build one a lot faster, but I've done a few.
