I have the wheeler and it does just fine. Honestly if I were you and was going to do a bunch of receivers I would come up with a way to do it without the lapping compound. It gets inside the receiver no matter how hard you try to keep it out.
I had a couple of ideas but never did anything with them as I don't really do it enough to make it worthwhile.
It wouldn't take much work machine tool wise to make it work and would be good practice. My one idea used sheets of wet dry sandpaper so if you really wanted you could do something coarser or finer than 220 grit. Though in my experience 220 is about the right compromise between material removal and resulting finish.

Hi, what are you lapping? The face of the threaded piece?
Yes he was and he did. Now we see what the fruits of his labor will be if he catches some decent weather.

I have one from wheeler. Actually two because one doesn't seem to be centered. I called wheeler they sent another kit.

Thanks for the clarification I'm not new to ars but I'm just starting my first build and hadn't run across this yet.
While it is not an absolute necessity it never hurts. A local knowledgeable shop will usually do it for $25.00 or less. All of mine have been done since I started doing this stuff last century. Anecdotal evidence suggests that in many cases it does improve accuracy and in some it even stopped repetitive bolt breakage, 6.5 Grendel, so it is a good idea.
