Apologies for the long answer. I do not compete, however in my line of work I deal with precision, accuracy, Cpk... I enjoy target shooting and try to eliminate as many variables as possible, I want to be limiting factor not the equipment, at same time there are diminishing returns on investments when I become the limiting factor.
I started eons ago with a Remington BDL Varmint in 308. Following discussions with several members it was trued and a heavy Broughton barrel installed, knob modified, trigger adjusted (pre-nanny state trigger), VAIS muzzle brake. Installed an AICS and I found it surprisingly comfortable. Then again thanks to this website I acquired an AI/AE (there was no MKI, II, III) really wanted an AW just could not pull it off.
The Remington outshot the AE with some loads, the AE is more consistent and reliable. On the Remington over the years I had an extractor failure, and due to cold weather a sluggish firing pin. AE remains a hammer. After 3500 rounds it remained sub moa. It now sports a 6.5 CR barrel.
Then I acquired a TRG 22 on a deal that was hard to pass pass (NXS scope, factory bipod, brake, scope mount, hard case). Lighter, better trigger, accurate, 26" barrel, can't get over the plastic (ok, "composite" components) This was developed from a competition rifle; does not feel as robust as an AI
Three years ago I acquired an AT, I was intrigued by the barrel modularity, folding stock and renown accuracy. Not disappointed. I recently sent it to AINA for a headspace check as I noticed that on the AE the 308 gage felt more snug than on the AT. Communication with Scott Seigmund and Tim Trend was prompt, polite. (Great folks Mr. Irvin) At their recommendation the rifle was sent and it was returned in a reasonable time.
Is the AT worth it? it is too me. I still have the AE, the Remington and the TRG. Most frequent rifles that I pack to the range: AT, AE, it is a toss up between the Rem and the TRG
Why? inherent accuracy, robustness, repeatability, ergonomics (fits me), value, customer support from AI, when I first purchased the AICS stock one of the screws was missing. I posted my question and Tom Irvin offered to send it to me (check his position at AI)
CDI (chicks dig it or bling factor) I was at the range with the AE, Remington and the TRG. A couple of guys stopped by and were admiring the rifles, I let them shoot the TRG and the AE (no interest on the Rem) The overall comment was the AI was preferred, why? They used in video games! FWIW they did better with the TRG. LOL
