      Compared to a different unit, no names but blue and finicky, this is truly an improvment. Feels sturdy enough, and works great flathopped. The spring included was a tad to long, but easy enough to shorten slightly with plyers. 10/10 would buy again.

      Great quality seems compatible with my build, haven't had a chance to try the hop but the fit is nice. the build quality is great, big spring on the barrel instead of a puny spring of the body and a nice metal hop up adjustement wheel.

      The hopup unit is ok. Not the best on the market for this price. It needs a little triming becouse there is allot of casting residue. The barrel fits shug. It looks coop in the gun. Overall a decent hopup unit but don't know if i would buy it again due to poor casting.

      Feels cheap and doesnt seal well at all.
      Probably pairs best with a slong gearbox. The wheel is very stiff, so that is good, and it feels like the adjustment wheel is cnc'ed, but not the rest of the hopup housing which isnt necessarily a bad thing, but will result in more lemons.

      Don't waste your money on this crap. Your oem cheap hop up unit will work 10 times better.
      This unit don't sit well on the barrel, the ajusting ring touching gear box really hard, to ajust nes juse screwdriver and scrub betal to metal. And in the end no mather how you will ajust it, it will be owerhoped all the time. Old hop up unit with the same bucking,nub and barrel works perfectly. So for the other inner barrel set i have i will order cheap oem specna arms hop up unit and this one will go to trash bin.

      I used it in my Cyma M4 replica... I have installed a Maple leaf barrel and a maple leaf hop up rubber and the Slong hop up unit. The chamber has a very good airseal and its very precise when correcting your hop hup... Would recommend!

      Solid HUU for the price. Seals very well and in combination with a longer barrel it added 0.4J to my AEG. Good budget Unit all things considered - will be purcharsing it again should I need an M4 HUU.
