Product Description

 

CNC Aluminum Hopup Chamber EVO unit is precisely machined to perform accurately and consistently on the ASG 2018 CZ Scorpion EVO-3 Airsoft Rifles.
The Hopup Chamber EVO unit is built with a Precision Aluminum Rotary Dial Knob for fine hopup adjustments and equipped with 4mm Flat Soft Bucking Nub (6mm Bucking Nub is optional) to perform best with R-Hop and Standard-Hop to keep the BB shooting accurately and consistently on every single shot.
The Hopup Chamber EVO unit is designed to accept the 18.5mm nozzle length, and fully compatible with most aftermarket soft and hard rubber buckings without losing FPS or dropping BB during use.
The Hopup Chamber EVO unit is wisely built with a self-centering inlet to ensure the hopup unit is inserted exactly in the center of the 11.5mm inner bore ASG EVO-3 gear box outlet without wobbling.
Also included an advanced CNC Delrin Locking C-Clip to hold the inner barrel tight in place without wobbling and twisting.

***The Dual UV LED Tracer Module is an add-on option to glow BB in the dark. Operating Voltage from 7VDC - 15VDC (2-4 cells LiPo, 6-13 cells NiCad). (Sold separately)
***Test results: FPS might be increased from 10FPS to 30FPS over the stock setup. Please check your FPS!

This is very hard to find item.
Size: 1 Quart, Style: 6-Pack, Configuration: Euro LX 0W-30
This is one of the lowest VOC oils. Important if your vehicle is GDI. Should help keep valves cleaner.

Went with a 30 weight because of ambient temperatures
Size: 1 Quart, Style: 6-Pack, Configuration: Euro LX 0W-30
Running this in my wife's 2016 Subaru Crosstrek. We live in Arizona and 100+ temps is normal thing. Did a lot of research on this before I decided on running a 30 weight, technically a 40 weight is recommended for our temperature. I noticed that her car was rattling on startup and was worse when it was a hot start. After switching to a 0w-30 I noticed the noise was substantially less. Fuel mileage was not changed she's still averaging 32mpg with her manual transmission vehicle. I've done my research and yes I know about staying with the factory recommended weight but we don't see subzero temperature and we are definitely not seeing the the average 80f summers. 40Fwinters and 105F summers are the norm here. Yes ambient temps effect oil decisions. I also prefer Euro Spec oils over SAE because of Europes extended drain intervals of 10-12k miles. I change every 5k or 6 months.

Fits perfect in my 09 Accord 4-cyl
Style: CA10467
Super easy to install, good quality, fits correctly. What more could you ask? A performance gain, you may ask. Ha. This is a gutless 2.4L 4-banger. No performance to begin with, and no gain after installing this. :-)
