I have been a little negligent in documenting the whole process but here is where things are at the moment.
I forgot to get a shot of the grip area but here's the forend with the sling swivel holes filled in and some other areas where the foam was exposed.
One of the front flush cup pockets done and tapped. It's 9/16-18 tap btw for those Grove-Tec flush cups, they'll be epoxied in towards the end after I'm done sanding and what not. I drilled it with a 1/2" drill bit with a piece of tape so I only went in as far as I needed to.
Buttstock area where I filled in the two holes shown earlier with JB Weld WaterWeld and sanded it down. I used a small round file to chamber both the inside and outside of the hole so that when I smashed the putty in there it'd have a better bite and resist any moment one way or the other. In theory anyway.
Cut off the nastiness in the back and sanded it down. I may end up taking a little more off the back depending on how the LOP works out when I get the new recoil pad.
Modified Magpul DBM so that it works with the stock.
This is why the rear magazine guide had to be contoured the way it is, it has to clear the interior receiver bridge.
I'm planning to clean up the inlet for the DBM today so I'll be sure to get pics of that later on.
