"First of all great great great unit !
I just install this bad boy on my custom made M4 and it warm flawlessly BUT it was a bit of hick up due to all my mags are PTS EPM mags if you have this mag and combo with this hop up unit make sure do not fill your mags to maximum it will cause some weird action like BB’s will not shoot out properly
And make sure you have the correct nozzle size also other wise you will not get proper airseal and be aware this unit will increase your FPS by 9-10% so be aware of that as well due to some of your guns might already reach the limit at your local field
And choose your bucking wisely too it will do a big play with this hop up unit too
All in all great unit it just very picky on what’s your combination are.
"Love this hop up BUT be aware it will increase your FPS roughly 10% due to how good the air seal this hop up is but overall one of best hop-up chamber I ever own so far.
"Let me start by saying this:
Understand what you are buying and how to use it (videos online).
To the one-star on this post:
Completely disregard the one-star and try this thing out, chances are that there was an improper installation, customer received a lemon, or ordered/sent the wrong product.
I received the ME Pro and went to a local airsoft shop with a Krytac Trident MK2 and they installed the standard arm with prometheus nub and purple bucking WITHOUT the R-HOP damper onto a prometheus inner barrel WITHOUT an R-HOP.
They had to dial it to 10 (Maximum) to get it to hop .20s. No idea what was going on there but it was not the shops fault because even I was a bit confused at the sight of this thing.
We went home and I installed this thing in my Lancer Tactical M4 WITH the flat arm, R-HOP damper, and R-HOP'd prometheus inner with prometheus bucking. At 6.9 it was dropping at around 185 ft (GREAT) and at 7 it was slightly overhopping (Damn near Perfect).
Conclusion from what I experienced: Mess around with it, try different setups on different guns, understand how it works and it may me the best thing ever. HOWEVER if you have a Krytac chamber or any other rotary hop up thats just great out of the box, I would not consider this an upgrade unless your going for the tracer unit!!
