(Write a review) "Easy to install . If you don't fond an R Hop then there's an extra arm included for you to install a standard nub hopup . Comes already installed a R Hop if I recall . Take apart and replace with nub . Make sure hop is set to 0 . Comes with a small instructions paper . To get it on make sure the dial is flushed with the hop to have an opening for the nozzle to slide in . Make sure you have the hop spring loose enough where you can put tension on the hopup and the barrel . Don't tighten the two screws holding the hop up to the barrel too tight and you'll be fine ðŸ¤™ "Nice machining and very high quality. Feels and looks soooo much better and more premium than the cheap stock hop up(which cracked on me). Dial is very stiff but always holds position. I tried two different buckings with it. The first was a maple leaf 75 degree bucking. Seemed to fit very well in the unit. At first it would only feed hi caps, then nothing at all. Changed it out for a krytac orange bucking and now I am literally reaching well upwards of 80 yards with the stock barrel with great consistency. I am very very impressed with this combination. Note however that the krytac bucking was a much snugger fit in the hop up unit which made it a bit more difficult to install. "This was it. This was the gauntlet of hope for the VFC scar users around the world. I bought this with an AST 80* (as it recommended) and the Prommy 407mm 6.03mm barrel.
I compared the stock setup with stock internals then replaced the hop up unit with the new parts and the results were spectacular. Accuracy became soooooo good (.30g bbs). I gained maybe 30 feet of range and probably got an fps boost too.
HOWEVER-----My shots were very consistent and accurate...if I tilted my gun. Shots would veer one way but consistently. I came to realize something was defective. I know it wasn't the bucking because i replaced it twice. Not sure if it's the unit or the barrel but I bet its the barrel
Pros: consistent, FPS boost, Perfect airseal, dial stays in place, solid construction
Cons: Im getting inaccurate yet consistent shots becasue of some defective part. IDK what it is
