Going to be building a new 10mm AR to replace my current blowback 10mm AR. I love my current 10mm AR more than i expected and feel like i should upgrade to something better

Trying to decide if I should use the CMMG radial delay or go with a Macon Armory direct impingement uppers. Im not sure if there is going to be a big difference in between them.

I have a CMMG 45acp and i really like it with my suppressor but not sure how RDB works with 10mm. Also it does still give some gas back with rapid fire

Unsure how the DI on the Macon 10mm upper will handle different loads and suppressor vs none.

Reliability is going to be pretty important because this will be a backpack/trail setup

Also im not sure if the Macon is avalible in FDE or only in black. trying to go to an FDE scheme

Will be using a CMMG MK10 lower so will be compatible with either

I'm guessing Rudy of Macon Armory ( @Mad-Machinist )  would answer your questions about his DI 10mm use with different loads and suppressors.
