HS detachable mag?? for 6BR and 6.5G

[Ogre6br]

HI

The action I originally wanted to make into a grendel is a no go so I'm looking to build my 6.5G on a Rem 700 SA,.223 boltface).

Looking at converting it to a HS precision Detachable magazine bottom metal and am wondering if the grendel mags will fit this bottom metal??

HS also make a 10 round mag that looks like a grendel mag from the picture but I'm not sure about just going by looks.

Can anyone help here??

If the Rem 700 action won't work without major difficulties what about a Stiller Predator action with HS detach mag bottom metal.

THanks
