"I’ve owned this rifle for about a year now, very reliable and consistent FPS and accuracy. The mini silencer tip can be removed, it is the common 10mm ccw thread. I used a 2” barrel extension and added a full length silencer and ACOG scope for a DMR look. I’ve tried 11.1 volt lipo with no issues, but prefer running 7.4 volt lipo. With an in-line MOSFET the 7.4 performs well and is worry free. Great performer even in stock form.

"This gun is amazing, it is extremely light and is really powerful. Don't put it an 11.1 battery in it just use a 9.6 it works literally the same. As for the orange tip I don't know if it come off. But overall 10/10 GUN BUY IT!!!!!!!
