I received an email from Magpul saying they just released there MOE Hand Guards with the M-Lok system and polymer offset light mount. I am glad Magpul is still going to make the MOE hand guards and re-designed it for the M-Lok system. I like the MOE hand guards. I have a MOE hand guard on my work rifle. I really like it. I do not carry for the new SL Hand Guards.
It looks like the new polymer offset mount will work with the re-designed MOE Hand Guard. I am differently picking both items up after the New Year. 
Good to know.
Great. Now where the blank are the MOE SL mid lengths???
I’ve got the Magpul SL handguard on my Sig M400, I like it much better than the stock AR type handguard. Now I just need a scope.
