"WOW!!! I ordered this gun as I'm a noob and didn't want to spend an exuberant amount of money if I decide to wuss out. I'm sooooo glad I did. The design is like no other gun I have seen. Its weight is decent and seems very sturdy. The hop up is a tiny difficult to get open if you don't have longer finger nails, but still not a problem. I went to my local Airsoft Arena and had it tested on their FPS Meter ( I'm sorry I don't know the name exactly, again I'm an older dude noob) and was shooting at 396.8 FPS-370.1 FPS So for me I have to learn how to lower my FPS to 355 or below. Sad me... A gun that's too powerful. LOL The gun is Epic Looking, Sturdy, has easy access to Battery Compartment. I Love this Rifle so much I don't want to give it but 1 star so others wont buy one and destroy me with theirs. Seriously.... For me... I'd say to definably have one in your collection at least. I mean its a great gun in my opinion. Buy one if you can. Also... I live in Colorado. The shipping was fast and had quality packaging for safety of the delivered product.

"Definitely different from the typical M4s and AKs you see out in the field, got a lot of attention from people asking what it is. Great price for a start gun with decent performance or for someone that wants a cool looking gun to upgrade. Easy battery access for a quick change out if it dies, recommend butterfly type batteries, fits easier. You can tell most of the weight is at the motor and gearbox area, the rest of the gun feels light. Kinda hard to open the dust cover for the hop-up when you don't have nails, even harder with gloves, but that's a me problem.

•Unique design
•Quick battery access
•Great starter gun
•Easily upgradable
•Kinda light

•Difficult to take apart to upgrade
•Might have trouble opening the dust cover
•Slightly below average performance (but can upgrade)

"Played it today good mid range weapon. Will make a note for you if the trigger feels jammed change battery this weapon will let you know the trigger on mine got stuck then fired slow so I grabbed another battery and up and going. Also good to have a low power weapon as well cuz mine was able to use that battery while this monster used fresh.

Good weight when slung feels like a regular rifle. Enough that you feel it there but not fatiguing.
Good mid range fighter
Fair fire rate.
M4 mags do work. Note high caps with wheel feed better than mids also drums make sure it's is the right length or shape otherwise it will not go in buddy loaned drum from a vector M4 style but did not fit due to shape

Too heavy for kids to use all day
Would like sling points but will say slung min through the stock giving me a single point did work fine just would like a defined point.
May of overlooked or may be just first time noticing a weapon that does this. Trigger feels jammed at low power thought it broke scared the hell out of me til it fired like a slug then realized what happened phew.

All in all good weapon outfitted mine with a bipod and gonna get a scope as well to see how far she truly hits. May tinker with internals then again may not. Overall out the box does well for mid to close range can hold its own in an outdoor field well and if in a building collapse the stock makes it okay for tight spots. Honestly though for that close carry a pistol or knife though this is a rifle not a normal close encounter weapon it shoots over 300 fps and will hurt like hell.
