ar upper and hand guard question

[CaneyRiverDog]

I have never built an AR15 before and looking for advice and help. Im needing an upper preferably in bronze. I would like the barrel to be shorter than the rail. I have a faux suppressor for now that I want to slide down into the rail and mount to barrel so that it barely sticks out of the rail. Where can I get these things or get the parts to put on together? Any help would be appre iated...picture for reference

Be prepared for sensory overload.

If you build you might have about as much money in tools as your first rifle.

Be very careful with this setup. Your hand will be forward of the muzzle. The bullet will be traveling through a suppressor, but suppressors can fail. Your hand will also get hot so a handguard cover could be a good idea. A small hand stop on the handguard where the muzzle ends is also a good idea. You will probably never shoot it without a can, but if you do....you'll never do it again if your hand was forward.
