When I did mine I had the second recoil lug dovetailed into the barrel after I had bedded the barrel into the forestock. I smoked the barrel down on to the wood then double tapped it from the front of where the second recoil lug was marked to go forward to the muzzle and smoked that down to give me the light float then cut in for the recoil lug and glass bedded the lug with the all faces taped except for the rear face. I always bed on wood and the smoker is the best accessory for doing that.

There’s an old M4C thread with testing on that subject matter.
