"I can see that most people found the fit to be too tight, but I saw this as a great thing. Even though the area around the arm required a few swipes with the sandpaper there is no way you will lose hop from unadjustment while shooting. Very secure fit on everything and a much better experience than the other hopups I ordered. The adjustment wheels fit nicely and a shim is included for even tighter tolerances. If you love that perfect fit and hate loose parts, you'll appreciate this.

"The fit of the Hop Up lever that goes up and down was VERY tight. I had to thin it out by taping a 200 grit sand paper on a glass table and evenly sand down the flat faces of the hop up until it was able to freely move up and down.

"No complaints about the quality. Everything seems all good. A bit of instructions could help, but the Evike product pictures were good enough for me to figure it out. Just a heads up to folks, not a complaint about the product itself, just it's fit. It did not mate properly with my G&G Raider. I think there is a pressure leak somewhere, as my fps dropped from 400 fps to 300 fps. Product seems great otherwise.

"The swing arm did not fit inside the hopup and had to be sanded quite a bit to make it fit. Tried Mad Bull Shark bucking on Mad Bull Black Python barrel and could not push it in. Even after managing the bucking the c-clip would not fit without modification. C-clip ridges also had to be cut in order to fit inside outer barrel.

Did not expect miracles, but this definitely didn't feel like a quality piece. Stay with ProWin.

"Very stiff
You do have to assemble with easy assembly
Doesn't work with matrix flat hop
Kind of hard to adjust but very persistent

"DOES NOT FIT IN KRYTAC!

Warning: This hopup will not fit into krytacs, the clip is too big and it will cause it so no mags will feed. Youre better off sticking with the stock Krytac chamber or a prowin!

"All metal Hop unit.... Casting was not great. And the top arm had to be sanded down to fit into unit. Clip around barrel is not great quality... a bit over hyped imo.

"Came broken and i could not use it. It also seemed like a pain to assemble. My local field uses these in their rentals and it is very hard to move the gears

"Poor quality control. I installed this in my m4 and it didn't feed. Removed the hop up unit and discovered corrosion inside the bb feed tube blocking the path. I had to removed it with a file it appears that the coating they put on the unit did not adhere well. seems to work okay now after filing it down but any part that is brand new should not have these issues.
