I am a bit confused over which AICS style magazine is best for 308. I have read some Oryx reviews where there were problems with Pmags and that the polymer MDT mags are fairly thick and may not accommodate longer COALs and that they may be a bit tight and not drop free.

I have also been looking at metal AICS options and MDT lists two versions for the 308, one is described as (standard) and the other is described as (no binder plate). Of course there is no description or information to tell me what 'no binder plate' means or what chassis/furniture they would be for.

Any help will be appreciated.
