"Excellent way to have a gun which can play in both CQB and Outdoor Field.

Pros:
+ Can adjust FPS between 250-440*
+ I find it delivers crisper blowback
+ Has tool for quick adjustments

Cons:
- Occasionally has large FPS variance (up to +/-20 fps)**
- At 'max fps' setting delivers lower fps than stock
- At 'low fps' can sometimes misfeed/sluggish blowback

* tested with 0.25 g bb with stronger floating valve spring, stock plastic nozzle, ratech trigger group and ratech bolt carrier, and 380 mm 6.03 inner barrel.
** fps variance is reduced with stronger floating valve spring

"Allows you to adjust your FPS on your WE open bolt rifle from about 300-500. All you need to buy is this and your good. Works just as it should, watch youtube videos to figure out how to install it. It's not hard.

"Works exactly as it should, no fuss, doesn't change during use too, chrono'd within 5 fps at the end of a day of use (could be because of tempurature change) I get these with every WE GBBR I buy, having the ability to adjust the fps is awesome, pure awesome. Installing isn't the easiest thing, but it isn't too bad either, there are videos on how to install it that make it quite nice rather than having some poorly drawn instructions in another language. BTW, mine didn't come with instructions, but I've done several of these and I have it down.

"Works Great to adjust FPS on Open Bolt WE Gas Rifles. I use Gas gun exclusive and i have this installed on all of them. Some modification of the air nozzle may be required depending on what gun your putting it in. Just you tube the installation instructions.
