Has anyone dropped a Bergara into a Rokstock?
khuber84's response to you is spot-on. Bed a pillar for the front action screw and there's no need to bed your DM (unless loose fit/gapped around the inlet opening). Bedding a front pillar does not necessarily require bedding around the tang, front screw, or full receiver.
Hoping to be helpful, here's a list of 700 considerations based on my (1) Rokstok experience + what I'm seeing posted by others/PMs:
- The Accu-Block represented by Stocky's is meaningless if (1) the receiver sits too low, (2) there's space behind the recoil lug, and/or (3) the barrel sits too low in the channel
- If a barreled action sits to low, fair to guess that there will be a DM feeding problem
- I doubt there will be any need for a rear pillar
- If you need to buy a front pillar, be aware that there are different lengths per 700 SA, MA, LA - no matter, it's worth having all three sizes on hand in case there might be a height or feeding issue
- The bottom of the pillar is to be set flush with the bottom flat of the DM metal inlet
- Understand that pillars ensure ideal spacing for d-mag position and feeding
- Make sure you test your magazine feeding before bedding the front pillar
- Will likely need to buy a set of extra-length action screws, then grind to height
- Pillar drill bit is 9/16" and be sure to use a drill press and a vise
Suggestion to Rokstok stakeholders: Do like Manners and deliver 700 stocks with 9/16" holes for action screws, include a loose set of pillars for the new stock owner to make his own decision.
Note that the front pillar I used created the perfect height for barrel clearance and mag feeding, so ended up being an easy fix.
See pillar reference for Front and Rear:

Am curious how many 700 Rokstok owners received a true drop-in. A tapered, larger diameter CF barrel might give a false sense of proper height if the fatter end of the barrel is sitting on the channel. Run a dollar under the barrel to determine whether the barrel floats in front of the lug.
Edit to add that washer/shimming around the front screw is a smart fix till making a pillar or bedding commitment.
