I'm not sure that's correct. (specifically this post...but also the others that say "any")
True...that if you re-wire your mechbox to the rear, then you have a much wider range of forend choices.
Not true...that almost any TM-based RIS/RAS forends will work with the King Arm delta ring.
Compare pictures of TM vs. CA/KA/G&P/RS delta rings...the shape/configuration differences are obvious.
That said...if you're using RIS/RAS setups that replace the delta ring with a proprietary barrel nut (i.e. DD, Noveske, Viking, etc...) then all you need be concerned with is ensuring that the receiver threads and the barrel nut match. There are two major threads used...one that can be rethreaded to the other with a proper tool. Different manufactures of different forenends/delta rings use and have different threading. Some manufacturers have put out extra barrel nuts to match the other threading (i.e. MB DD barrel nut for RS/PTW/etc threading).
Just my own $0.02 guys....while it's helpful to keep things simple for new guys, it's more effective to be a bit more complete in what you're suggesting. If you know specifically...then chime in. The (paraphrase) "I put a MB Diablo on my KA M4, the threading worked perfectly...no issues" is helpful.
If you're taking wild ass guesses (there's been a lot of that recently) or making large/wide assumptions then give it a second thought...'cause it may cause more confusion than not for someone who doesn't know enough to pick out those differences.
