[quoteAn M16A1, the original design. I don't like the new stuff. ]Or an M2 Carbine...maybe both.[/quote]M2? Don't bother! It's just not that much fun.
Sad thing is, NFA legal MGs and SMGs are all 1986 or earlier technology. There isn't much in the way of "new stuff" available.
If ammo was covered in the cost as well, I'd say Ma Deuce.
Barring that, I've enjoyed shooting an M-60 at cross-canyon ranges, which is fun. But the ammo's expensive there, too, isn't it?
Hm. Looks like we're down to SMGs. I sure have appreciated the quality of a HK subgun like an MP-5 with a can on it (do I get the can in the deal?). Sadly, I don't think any of the 10mms were made early enough.
The plethora of uppers available for M-16s may just win the day, the more I think about it. Maybe an Armalite in .308, so that I could get the conversion kits to .243 and other fun small stuff. (Shrug) It's a fun game to play, isn't it?
