their web site says some adjustment may be required for use in KRG chassis. What kind of adjustment. I ask customer support over the phone and got a I don't know answer we don't have a KRG chassis here to try them on. Any experience here? If so what adjustment?
 
Since the KRG X ray chassis is made for both Rem 700 and Tikka T3 actions it helps to distinguish which you are planning to use. As a "general rule" plastic/polymer mags do not fit into Tikka T3 actions without the feed rails being opened up a bit. The feed rails are narrower on the Tikka's than on the Rem 700's. Original AICS 223 mags won't fit in an unmodified T3, but I never tried the MDT plastic one's. The reason being that Accurate mags .223 mags fit T3's so well being all metal with just plastic inserts I never had the desire to try anything different.

You might want to PM KRG here and ask them directly. They might have a better handle on mag fitment in their chassis than MDT.

The MDT mags may not be drop-free in a Whiskey 3 chassis. On mine (700 SA), I have to move the forearm all the way forward against the screws to have drop-free ejection. Forearm position does not affect feeding though.
