Wow, mentioned with such love, how'd I miss this before?
I have had a few conversations with folks about the AICS setup, and have NOT said it is bad for "healthy" sized people. My specific comments have been:
1. The palm swell favors those with smaller hands. People with large paws will find a good strong-hand position to be challenging. Trigger pull suffers if good hand position isn't possible, especially on thumb-hole stocks.
2. With the 1.5 version (adjustable cheek piece, adjustable LOP), the stock ergonomics are quite comfortable.
3. Magazine lockup and rifle function are superb in all the AI versions I have used.
4. Bedding is usually unnecessary as the AICS has a bedding block that locks up well.
5. The stock is, overall, not a bad deal, compared to comparable-quality other options (McMillan, Manners, etc.)
I am 6"5' and 210, I liked everything about my AICS 1.5 except for the palm swell - and couldn't find a way to make the palm swell comfortable without drastically "modding" the skins.
When you consider that a McMillan A5, pillar and skim-bedded and with bottom metal, runs about $1000 and a Manners with their chassis system runs about the same (the Manners chassis, by the way, runs AI mags and is a great piece of gear), $900 for the AICS isn't a bad deal.
I always recommend one at least get behind the stock before buying it, though I know that isn't always possible. I've shot virtually everything out there and have strong personal preferences; however, I appreciate that some have very different preferences.
