Reviewer: Luke Oster from Lidgerwood, ND United States

Awesome gun July 17, 2015
Reviewer: Mike from Oklahoma  
This gun is Awesome, I am very much enjoying it, I would highly recommend it to anyone, it hits hard & is fairly quiet so it won't alarm the neighbors like some pellet guns, its great for discouraging stray dogs, cats, squirrels or Raccoons from tearing up property "without" killing them, its painful but the plastic bb's are light so they don't penetrate the skin like a pellet gun does, its great for target practice with card board targets. Buy one you won't regret it.

I give this gun a 4.5 January 28, 2015
Reviewer: Bayard sweeney from Erie, MI United States  
This gun is great! I love it! Very powerful and accurate! The only problem I had with it was installing the peq box and getting the wires to fit through the little holes.  Only thing i would change is to make those bigger so I could fit it through easier.  In all great gun!

Durable and Powerful June 21, 2013
Reviewer: M. Van Meter from Virginia, US  
I got this gun about 3 months ago from and i gotta say... this gun is very durable. Playing with friends is a blast, especially with them ooing and aawing at the ROF (credit due to 9.6battery, low resistance wiring and mosfet) Going to the field, the gun measured at around 428 fps, which is awesome for outdoor games. It was too powerful for the field I was at though, so I had to purchase some .28 bbs to bring the fps down. You wont play many indoor games with this gun. The accuracy is awesome. I use (and although I know I shouldn't) low quality .2s from wal- mart, and the accuracy is still astonishing. I made the right decisions of getting a red dot sight, as it is ideal for this gun as the sights flip down. (The iron sights are still really good sights) I am throughly satisfied. Tight fit on the battery. Do NOT FORCE it. I made that mistake and sheared some wires
