Ive had this gun for a while now and i use it all the time. Its definately worth every penny and just looks amazing. The bolt catch has started to catch when i press it down and not pop back up but i think its just a spring or somethin on mine. Its amazingly accurate and has the perfect fire rate. Mine shoots at 348 fps which is perfect for accuracy but still has great range with .20g.
easy to put battery in
works well with pmags and all m4 mags
comes with black flashhider
great fire rate
bolt catch isnt as smooth as it could be
nothing else whatsoever
