I did it to a DPMS slabside with a Wheeler and blue loctite in 300 BO, it is a parts leftover assembly, so no loss if it was a mess. I get 3/4 moa at 100 yards with a YHM can and factory 190 subs, so no complaints, no idea if the added prep made a difference.
I did the lapping to VLTOR uppers with a Shilen and a Lilja barrel, both in 6.5 G, didn't need it in either case, uppers were square.
The VLTOR I used with a Stoner (Liberty) 24" 5R barrel shoots 3/4 moa at 100, with nothing more than just attaching the barrel and proper torque, so I'm not an advocate, lapping and bedding done well, it probably doesn't hurt anything.
