I still have it. And shoot it.
Everyone claims the bolt throw is silky smooth. Well, actually they claim the bolt is silky smooth. Because the entire throw is not smooth. It is very smooth if you just run it forward and aft, but if you actually lower or raise the bolt handle(on a depressed sear) it is far from light and smooth as a custom 90* two lug.
Reliability no matter what. AW mags are not the most reliable mags out there. And that's what an AT and AX use. I have to pull my followers and springs out every once in a while and stretch them. There are threads on this forum about bolt shrouds exploding. There was a widespread fire control issue that AI warrantied for customers. Ive seen guys have melt downs with their AXs at matches, granted trying to shoot a BRX in it. The ultimate reliability no matter what is hype.
The spongy 2.5lb two stage trigger with springy follow thru for days is far from a great trigger.
Barrel swap. This is done on so many other platforms these days....that also give you 223, SPC/ PPC, and magnum bolt face capabilities.
Chassis are very bulky and you're very limited on alternatives.
A spare bolt costs $700
I'm shooting a two-day match this weekend in a very hot, dry, dusty environment. I have been debating taking my AI in 6GT or TL3 in 6 Dasher. I was about to take the GT and my buddy reminded me that this could be a fairly difficult match, so I deferred to the Dasher. The TL3 bolt is much smoother. I torque barrels on with a crescent wrench and muzzle flats for a perfect return to zero. I have barrels in 223, 6.5G, Dasher, Creed, BR, and 308. A TT Diamond is like a precision scalpel compared to a trigger designed for the military. The chassis is tunable for weight. Zermatt is Jonny on the spot with customer service or spare parts if i need them.
Don't get me wrong, the AI is a cool gun and very capable. I bought one just to see what the hype was. I really like the action. I have a comp trigger and it really isn't much better than the stock trigger. I debonded my rifle and spent considerable effort and money putting it into an MPA and i just pre-ordered an AO chassis.
But folks on this forum really do go overboard with their enthusiasm sometimes. To the point where it's an echo chamber.
