Need help with 9mm AR15 Tri-lug barrel upper
I have a couple of 9mm AR15 SBR's. One is a Rock River Arms and the other is a Colt LE6933. Both have about 10" threaded barrels that I've been threading my TiRant 9 suppressor to. They work fine with this setup, but I always have to constantly check to verify that the suppressor isn't unthreading and the overall length is kind of long. I've recently purchased a B&T APC9 suppressor that's made to lock on using the tri-lug system.
I'd like to make or buy an upper that has a 5" or so long barrel with the tri-lug system. I'm thinking that the handguard would surround the suppressor almost completely when the suppressor is attached. This would minimize the overall length of the barrel + suppressor. Does anyone make an upper like this or the components for me to make one? Is there anything that I'm missing with this idea?

There also Foxtrot Mike, I know zero other than I've heard of them.
I have the TrosUSA 5” barrel on my SBR. It’s a work of art. Super accurate with 147gr plated subs and Titegroup. I run my Griffen Armament Revo 45 with the trilug adapter. Fits under a Midwest Industries rail. Love that gun. I’ll try and find you a picture of it when I have time.
