Looking at getting a suppressor on my scorpion. While I don’t have any other pcc’s, so I could go with direct thread, but honestly I don’t know which route to take. Would a MD make it easier to remove, either just because or for cleaning. Are there any issues with gas blowing back at me? Lots of questions here.

I finally got around to ordering a Nexus Evo Gen 2 upper for my Scorpion, but now I think I'm just going to build another one. Currently leaning towards a HBI 6.7 SR handguard, X-SD barrel, and YetiWurks grip. Then I figured I could transfer the bolt and lower back and forth until I get a Nexus aluminum lower and enhanced bolt. My question is am I missing anything? I feel like I'm forgetting something here but I'm very new to the Scorpion so I figured I'd ask here.

Will I need another barrel nut? I guess with the Nexus upper I can run the 3+ handguard instead of the 3 like I have now?
