Ordered this product when it first came out and I have to say it is my #1 go to gun. The stock and pistol grip are easily changeable to any m4/m16 version. Orange tip comes off easily to put on a surrpresser. The rails offer a could amount of real estate.
Easy to upgrade
400 fps for field
Good rate of fire with any battery
The charging handle and bolt have a in satisfying click when you pull it back but what ever.
