"Crazy accurate! I have used every type of hop up you can imagine, all the letters of the alphabet, I tried patches, and even modding the barrels, but hands down this is the easiest most cost-effective and time saving upgrade you can put into your gun.
So far this is the best hop a bucking in the market in my honest opinion. It makes my TM MWS M4 shoot laser beams and is easily the most valuable upgrade I did to my gun.

"Very solid bucking! I installed mine in my KJW hi capa and with .3s it didn’t hop all the way but was still hitting pretty accurately at 100ft plus. A solid upgrade over any stock bucking. The feed lips are more stiff than an average gbb vsr10 bucking which is great for air seal!!

"Put it in my SOCOM GEAR Les Baer Ultimate Recon slightly adjusted the hop and this thing shoots perfect. Great bucking and easy to install.

"I have used lots of bucking, and this makes my We Techs shoot laser beams-airsoft equivalent 👍

"Really good so far. Great setup in my MWS MTR. lifting .36 and .40 no problem.

"Absolutely great, but...
First off, if you're grabbing it because you were hyped about it, check ur groupings before you buy it, although it's cheap, if your gun already beams, there's no use for using this.
Besides that, if you're using a gas blowback pistol or rifle, and are looking for a first upgrade, definitely look at this bucking.
In a TM G17 GEN 5 (Evike doesn't sell that btw) with a 6.00 laylax inner barrel, it looks like it kept a very consistent group by having the BBs beam just over the front iron sight on .25s. However my main complaint was that the hop scaling (how much the hopup increases by) seemingly decreased, and probably doesn't hop over .28s.
Immediately I wondered how this would interact with the Poseidon inner barrels, since they increase range with the air cushion design.
If you're looking at buckings as someone who doesn't stock up on aftermarket buckings, consider this option.
