yeah, the caliber conversion thing is interesting. On the one hand, I was all fanboy about that with the Masada/ACR, then I thought about it. So you can convert your gun to shoot some other caliber ... that's cool, but every time you do it you have to rezero...or, if the gun actually RTZs as advertised (big "if"), you should at least CONFIRM zero (and keep count of how many clicks up/down/right/left your optic is, or keep a separate optic on a mount that also RTZs, and don't confuse anything ...) ... and how many times would that conversion happen...and if it did happen a bunch, how many times until you said to yourself "You know, this is a PITA and I wish I just had a gun in *insert other caliber here*"?
So, now I'm no longer interested in caliber conversion in rifles.
That said, if you got TWO of these ... one in .308 and one in .223 ... each would act as a parts donor for the other (for most parts, anyway) ...
Yeah, thoughts like that make my bank account cringe.
