Being pretty new to the Airsoft scene, I was not sure if I was going to like an AEG Airsoft rifle or not since I have always liked my Blowback airguns? This rifle is really nice and I find it hard to put away since I just like having it out to look at and hold. It is extremely realistic with all metal where the real Colt M4 version has it and a working charging handle, forward assist and dust cover which exposes the hop-up system for easy adjustments. The King Arms Colt M1A1 Metal AEG also performed very well with excellent accuracy and very high sustained FPS performance!
