Double Eagle Full Size M4 RIS Airsoft Low Power Airsoft Electric Rifle w/ Underbarrel M203 Shotgun Launcher

"Very good as a starter, around 300 fps with stock battery, around 350 fps with valken NiHa 9.6v, can fit matrix standard mags, M203 attached can be taken off, there is no bottom rail but you engineer your way to put one on.

"This gun totally exceeded my expectations on performance. Although the exterior is mostly made of plastic (other than the magazine), the look and feel of the gun still satisfies me. It weighs just over 4lbs fully loaded. Out of the box performance is decent. It survived three indoor skirmish days with no mechanical issues.
I recently swapped the 6.04mm stock inner barrel with a 6.01mm barrel. This greatly improved the accuracy, thus eliminating frequent hop up adjustments. It also raised the fps rating to an average of 335fps with .20g bb's. It pierced through a soda can at 25ft, so that was cool. I put a 7.4v Li-po battery in it, which improved the rate of fire significantly. The underbarrel shotgun works amazing in CQB scenarios. Excellent backup weapon if you don't have a handgun or other secondary. Plus, extra shells are cheap on Evike. The gearbox has some metal parts as stated in somebody else's review. I have yet to try and upgrade the internals. With my upgrades this gun has been going strong for over 8 months with no problems. I am very happy with my purchase. For indoor skirmishes & backyard play with friends, this gun is the best bang for your buck. Perfect starter gun for someone wanting to get into airsoft sport. Definitely recommend.
