Mc3 stock

What’s the bottom metal inlet on the stock? You may need to have the stock inlet and fit by a gs.
Can’t go wrong with a Badger DBM and some AI mags.
 
The Magpul DBM isn't going to work with an M5 inlet, even if you have a gunsmith open up the stock so it will drop in. The pillar depths needed for each are different. DBM's that use the M5 inlet pattern usually come with shorter pillars and new action screws so that it puts the magazine at the proper height in relation to the bolt and feed ramp in the action.

The Magpul was designed to drop in to the Magpul stock as a direct replacement for someone that is using a Remington 700 BDL floor plate and action screws without changing anything except removing a spacer. The pillar height for a BDL set up is taller and the action screws longer. If you tried to use the Magpul DBM in a stock that has pillars for a M5 inlet I'd imagine the magazine would bottom out on the action before it could lock in and the action screws would interfere with the bolt.

Got it thanks
 
What did you do to install and do you want to sell your Mc3 dbm

The Grayboe DBM dropped right in and ran without issue for me. There was just space around the edge. You could bedding it for a better fit.

I sold the stock and DBM early this year as the CF version was heavier then expected but a very solid stock for the price.
