I have a KWA RM4 ERG that has been upgraded with a new inner barrel, flat-hopped. I also swapped out the handguard for a free-float rail system.
I absolutely love this gun. I use it exclusively as my main gun. The quick change spring allows me to change my FPS in less than 3 minutes. Just need a good castle nut wrench and you're good to go.
