Precision machined and ground recoil lug in anaccustock?

Why not surface grind the factory lug? Sounds like a good option to me. 80% clean up on both sides get er done.
you will loose the alignment pen. Easy solution with index mark or 2 flute end mill and spring pin.

I also did what you did, but aquired one that already had the parallel profile. The bottom was too long and I had to trim it too.

The reason I did it this way was because I already had the recoil lug and it's thicker than the factory accustock lug. Once you start grinding the surfaces of the factory lug, I'm sure it will get even thinner. The recoil lug you have would have made my life a lot easier.
