||got this gun at the begginning of the month and waited until i played with it untill i reviewed it.
I dont think theres a big difference in internals between the RIS and normal combat machine m4s, so look at those for a good performance review. The light weight is great for if you want to attach a lot to the rails and the stock is comfortable when you aim down the sights. you MUST get a butterfly battery, it goes in the stock and nothing else will fit. The only downside to the combat machine m4 is the low FPS, but otherwise all around good. the mags wobbles but you should get a grip of some sort ecause rails are irritating to hold
tons of rails
better externals than chinese AEGs
battery is hard to get out
remember to get a holy cow deal with the gun
