From a performance(accuracy) perspective, is there any difference between the AIA M10 B3 and B2? I've been searching the forums for posts and from what I've read, it's possible to get 1MOA from a B2 with hand loads. But, I haven't seen much info on the accuracy of the B3 with the mini-gun barrel. The B3 is supposed to have a 1 in 10 twist, while the B2 has a 1 in 12, and that leads me to believe the B2 and B3 area likely to perform very differently. As I own neither of these rifles, I was hoping some of you could speak from experience.


Finally, there seems to be a lot of debate about the AIA M10 10 round magazines. Some posts say that they would have to be modified(a hole drilled, or something like that) to fit in an M14, becoming a prohibited magazine and something I'm not interested in. However, another post suggests the 10 round AIA M10 mag would slide right into an M14 without any modification(A legal setup from what I've been reading). Can anyone shed more light on this issue?
 
Thanks Stevo, that jives perfectly with everything else I've read/heard since I posted my original question.


Now I'm left to wonder how much of a difference there is between the B3 and B2 barrel. (Not that it matters too much to me, I'm just curious.)

Have you tried asking the folks at Marstar?
 
Nope, I hadn't asked them yet. I was hoping for an end user report. But, at this point I'm probably just going to go ahead and order one...
 
Placed my order yesterday. Once it arrives, I'll be sure to do some shooting asap. But, all I have for ammo is a bunch of SA surplus 7.62. (Not the most accurate stuff.) None the less, using the ammo I have, I'll be able to compare groups between my M14s(no scope), my Tikka T3 Tactical, and the B3. I'm looking forward to this:)
 
I thought I read a post with a comparison between the Portugese surplus 7.62 and the SA surplus stuff. Am I recalling correctly that the Portugese stuff was considered very good quality relative to the other commonly available surplus NATO cartridges?

Stevo: What kind of optics do you have on your AIA?
