Next stock work, to open the barrel channel I use a wooden dowel doubleback tape and sandpaper.
Sand out the barrel channel
Check often with the barreled action for fit, about 30 minutes later you should be done.
here is the final fit.
Next duracoat...
After the proper prep work spray it on, fyi the color is magpul OD green.
