I've been trying to run my RA-Tech aluminum nozzle for a bit and I haven't been able to get it to run a stable FPS. Worse case is usually a 100 fps jump. Best case I've gotten is a 30-50 fps jump. This is after switching to the stock spring. I'm wondering if anyone has found a way to stabilize this yet? Or should I shelf this POS until I can find a suitable spring for it?
Also of similar note, I heard that RA-tech revised the aluminum bolt, is this true? Is there a newer gen that isn't a POS?
