hi all, new here
I have recently bought a blaster which is essentially a gen8 m4 with a xm316 receiver and heavily upgraded gearbox, what I want to do is replace the stock handguard with an 11 inch alloy one.
what is confusing me is what sort of adapters I will need, as I will obviously need the threaded adapter for the receiver and handguard to work
but I also was hoping to have a metal outer barrel so I’m wondering how that will attach?? do i need stabilisers for the inner barrel? I have no idea exactly where to get those and are they specific to each model of handguard?
basically I want to upgrade to a longer handguard which is metal and have a stainless barrel and some sort of outer barrel which would allow me to use my suppressor style hop up but cant seem to find the parts to make it all work
