I'm with WH, I saw and handled the mm 11's and 13's at SAR. They both look really good and you are getting alot of gun for the money. I would like to get one but I think that I will be leaning toward the 13 over the 11 for a couple of reasons:
1. Cost of ammo, .308 is just ridiculous to purchase right now even more so than .223 and I have more 223.
2. Beta C's, I keep hearing that the Cdrums will be out for .308 but they aren't here yet. You could get one of the new allied armament drums for the g3 but they are only 50 rounds if I recall correctly.
