Hi, I have a green AI AICS stage 2.0 short action stock.
I use it for both a 243Win action/barrel and a 270WSM action/barrel.
The stock itself works wonderfully well, is extremely rigid and solid, an action can be laid in it in 5 minutes, is almost indestructible, comes with an "industry" standard box magazine system and attracts attention.
The only negatives are high price, heavy weight (something like 5lbs) and it attracts attention.
I wanted the best tactical rifle stock and that's what I got (at the time).
New models are coming out all the time so AI or another company (like Remington) might introduce a superior stock system but I still love the look of the AICS 2.0.
