"Got one of these for a customer’s Arp9 build. It was paired with a Prometheus stainless 6.03mm 300mm inner barrel, a Prometheus purple flat hop bucking, and a MAXX/EMG hop up unit. Results were amazing with this setup AS ALWAYS shooting lasers at a man-sized tree at 225ft away hitting every single shot despite wind and only using .25g bbs. Could have easily hit further ranges.

"Works great with the Prometheus flat-hop bucking. I put it on a madbull 6.03 509mm aeg barrel with a Prometheus flat-hop bucking and a pps hop-up and perfection.

"Out of the two I prefer the black nub but I did have to cut the front a bit to fit the window. That being said i've been hitting the 250 feet range with .25s. The blue one is a bit too soft but it still does well.

Bucking: Shaved KWA bucking
Barrel: Prometheus : 6.03 310mm~ (custom inner barrel)
Using factory KWA rotary hop-up
