Will a no gunsmith mount for a No.4 Mk.1 .303 fit my DCRA .308?

Is there any difference I should be aware of before purchasing one? I think they are exactly the same I just wanted to make sure. Thanks boys.

They usually use the charger bridge and the rearsight pivot pin holes.
Has the top of the receiver been changed at all ?
The B-Square mount also uses a ejector screw which comes with the mount.
I have the ATI , S&K and the B-Square mounts .
The B-Square , properly fitted , will hold the best IMPO.
The other 2 will eventually move out of place .

It will work just fine. DCRA did not change the receiver.
