Electric Airsoft Rifles use batteries as their power source and they shoot very fast. Some Electric Airsoft Rifles come with semi-automatic fire. That means that when you pull the trigger only 1 BB will come out at a time. Other Electric Airsoft Rifles come with full-automatic fire. This means that when you pull the trigger multiple BBs will come out at a time. The longer you hold the trigger down the more BBs come out. Check the description above to see which kind of gun this is and if it is right for you. Electric Airsoft Rifles don't require any pumping or cocking, just simply point and shoot. This is a High End Electric Airsoft Gun. Please only use .20 gram high quality BBs with this item in order to keep it in proper working order. Using anything else as ammunition for this gun will void the warranty and may cause it to jam. Also, to keep your Electric Airsoft Gun working properly, do not fire the gun when there are no BBs in it as it may cause damage to your gun. You must be 18 years of age or older to purchase this Airsoft gun.

Good solid affordable gun. Nade launcher is tuff to install but overall not bad.Bought it for my son it shoots great it feels very solid for a plastic gun it does have a metal barrel.It shoots hard and fast for the money.And i wont be upset if he breaks it.If you didnt buy the gun dont post a review in which you know nothing about the gun.

Very high FPS the only thing concerning me is that is the gun's material made of metal or plastic? Usually plastic air soft guns break pretty quickly, I'm just curious.

What is this gun made out of? if it is plastic, is it like is it that crappy stuff or the kind that feels really nice and doesnt break easily

By: Taylor 08-11-2013

The main component of this weapon is pretty solid, shoots fine, the forward carrying handle is loose and kinda feels real cheap. it has a standard 10 mm rail, once again, pretty solid but not top of the line, i personally suggest using the m203's battery case over the hop up but other than that its pretty good for its price.

By: Taylor 08-11-2013

And the carrying handle does come off for more rail space in answer to R's question

5 Rating

By: R 07-20-2013

And for any confusion, always use .20 gram bbs to ensure that your gun works properly. .12 gram bbs will ruin your gun and should only be used in spring guns (except snipers, use .25 bbs)

It looks great, i will get this gun and review back but does anyone that has it know if the rear sight comes off and there's a rail under it... if so i will get a red dot

By: Alex 07-12-2013

I gave this gun a 4 out of 5 cuz of the launcher I was a little disappointed in it but this gun is really good and very customizable and I would give this a 5 out of 5 if the launcher was stronger. Bottom line if youre thinking about buying this gun, just do it its worth the money! =) any other complaints not really about the gun was when I ordered mask wit it the plastic on it melted a bit so its kinda blurry on the goggles but that's just happened during shipping so don't matter

i bought this gun for my first electric gun and i loved it.the only problem with it is that its very high maintenance i had a few problems cause i didn't read the directions properly but once i figured out the hop could be adjusted and it took .20 grams it rocked. after about 2 years the piston broke and i was sad about that but i am thinking of getting this gun again

People don't understand that MOST aegs under 200 dollars aren't full metal. They are made of abs plastic which is pretty strong but people don't treat it like a gun and drop it all the time. But this gun is pretty good but don't use .12 gram bbs. Grenade launcher kinda stinks so just use the foregrip. I give it 4 out of 5. But great gun for the price

i bought this gun a while ago and it is AWESOME!!!!!!!! The battery is kinda hard to get in at first, but it's fine after a while. The high cap. mag is great and really comes in handy. however, you can't, as far as i have found, have the battery in while you have the rail on and the grenade launcher is a pain to get on.

Hey guys, I just got this gun, its pretty durable, and it has some plastic and some metal in it. I hate the foregrip though, it just doesn't connect right. Besides that, this gun is a pretty good start for beginners, or advanced players who know what they are doing. The grenade launcher is ok, but you need to use .20 g BBs, ALWAYS. Never use the .12 on this gun, it will jam and break the mags. Only use .20 g BBs! I'm warning you!

The quality of this gun isn't the good but the gun self is awesome the gnade launcher looks cool and helps you with ammo. It's not to heavy. The firing rate is great and so is the accuracy I reccomend you buy it. Oh and don't force any thing on the grenade launcher the flap on the side is to reach the ammo compartment.

By: Airsoft Expert Previewer 11-20-2011

If you read through all the description CAREFULLY, you can obviously tell. Also by looking at costumer reviews, which actually don't help that much with this gun, you can kind of tell that the gun is pretty decent. The mag rate of 300 rds is a very high standard for this low priced airsoft gun. The rate of fire looks pretty decent in the video. The grenede launcher is intestable because it is not seen. Thats all I have to say about that, other than that. I was wondering if it was plastic or metal, my guess being plastic. If you know tell me please. Im out.
