SLR hop up with threaded barrel

Just picked up my STD SLR and very impressed with it so far.
Question is how and where can I get a hop up to work with the standard threaded outer barrel

there is an inline rizer that will be spot on for you.

where, not sure


Thanks for that
I found it 13mm dia rizer

Correct, the 13mm Rizer fits and allows you to unscrew the SLR muzzle

Exactly what I am looking for.
