I've searched all over and I can't seem to find any real reviews on accuracy for these two or other worthwhile comparisons.  Anyone have some targets you'd care to show  Or ups/downs? I like the thought of being able to change calibers a little easier/cheaper with the DTA and the price is a little better but I have a pretty strong preference for actually hitting a target.

Thanks

I must be dumb or just plain lazy. What the heck is AI or DTA? And dang are you saying that there are rifles out there that have quick change barrels and bolts so you can use the same receiver for multi caliber rifles? And yet you what this to be fairly accurate? Interesting.

For your first question with over 4k posts I'll go with...

Linky for:
AI

DTA

There are a significant number of companies offering multi caliber rifles with a barrel or barrel and bolt swap: AI, DTA, Larue, LMT, Barrett, and Remington come to mind off the top of my head. My Larue's all come back to within .5" after a full disassembly and reassembly (barrel, scope, handguard all removed).
