I’m gonna upgrade my hopup and I know Rhop is better than Flat hop but I’ve heard they’re close. I can’t do an Rhop myself so I’d have to buy one which would run me $200 but I could do a Flat hop myself for $120 and I didn’t know if there was enough difference to spend 80 bucks more or if they’re close enough to where it don’t matter. And a side note if it matters I’m doing it for a 363mm 6.03 Prometheus inner barrel with an FPS of 375 - 390 and using .25g bbs in an M4.
