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 material, comes with a lot of stuff, however the battery is infuriating. It doesn't fit inside the grip and there is no way to fix it. I the only way I can get it too work was too tape the battery on the side and break a piece of the grip off to make it function.

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.

By: Marcus on February 22, 2015
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.
By: Marcus on February 22, 2015
By: Adin on October 16, 2013
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 on August 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 on August 11, 2013
And the carrying handle does come off for more rail space in answer to R's question
By: R on July 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)
By: R on July 20, 2013
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 on July 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
By: M4 on February 14, 2013
should i get this or the m4 zm81b or this and id get red dot with either 1 i get
By: Theseansterr on December 16, 2012
what BBs should I use it says to use .20 but reviews are saying to use .12
By: Theseansterr on December 16, 2012
should i get this gun and if i do can i get a red dot sight for it?
By: Matthew on November 23, 2012
do this gun come with battery and charger
By: Brian on September 29, 2012
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
By: A Helping Hand on July 29, 2012
Another thing all internals are metal and is the weight as a real m16!
By: Shadow Ops on July 27, 2012
To: Moose it comes with a good quality speedloader.
By: Moose on July 23, 2012
Does the gun come with a speed loader?
By: Ooo Mr.bossbar Ooo on July 04, 2012
airsoft guns, some plastic some metal, but this gun looks great
By: Fireblaze on July 02, 2012
pretty nice gun, but i wish the grenade launcher was a CO2 type not spring :/
By: Chris on June 28, 2012
good gun overall but grenade launcher sucks and the gearbox iz plastic
overall: good gun for starters and don't shoot it on full auto to long because plastic gearbox gets stripped
By: Airsoft12 on June 26, 2012
I`m so geting this gun
By: Jd on June 05, 2012
This gun is great i like how it has metal and plastic parts the grenade lancher works fine but it makes the gun heavy so i recomend to use the handle .the batery is a pain to get in though. but still ,great gun at a decent price.
By: Usmc on May 29, 2012
Can someone please tell me if I should buy this gun?
By: M4 on May 25, 2012

By: Combustion on May 06, 2012

By: Da Man on April 17, 2012
I got the gun about a year ago to test out but I gave it to a friend that was just getting into airsoft.Now he plays professionally in Dothan, AL. I'm ordering a batch of 30 right now.
By: Matt on April 13, 2012
This gun is amazing. All of you people who say bad things about this gun have no idea what they are talking about.
By: Snipr on April 11, 2012

By: Ike on April 11, 2012

By: Hetdogm on April 10, 2012
wating to get it!!!!!!!!!!!!!!!
By: Sduff74 on April 08, 2012
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
By: Snipr on April 05, 2012
Does this gun have a metal body.
By: Sexiness on April 03, 2012
good gun but i don't know how to load the grenade launcher
By: Monster Nom Nom on April 03, 2012

By: Lulz on April 01, 2012
I WANT THIS GUN
By: William on March 19, 2012
I hope that i ccan et ths gun when it comes out
By: Airsoft Pro on March 12, 2012
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.
By: Rocket on March 11, 2012
I got this gun over christmass 2011 and its still working awsomely buy this gunnn
By: ... on March 05, 2012
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!
By: Yourmom on March 02, 2012
i love this gun
By: Piggy on February 29, 2012
I'm who you should believe it may be plastic but its durable and partly metal only on the barrel though trust me I own one
By: Bman on February 23, 2012
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: J on February 23, 2012
By: I Love Airsoft on February 22, 2012
This gun is beast. I have it soooo customizable great for anyone. The orange tip broke off and I had to tape it, but that was all my fault. Great gun awesome price for everything you get.
By: Piggy on February 22, 2012
you guys are stupid it may be plastic but its durable abs plastic;the strongest plastic in the world! so you all need a brain transplant.
By: Kman on February 19, 2012
great starter gun i got it when i was 11 and now im 13 and it still works good. recommend using .20 bbs. its a great gun although the "grenade launcher" is rly a shotgun and that part sucks. Other than that its rly good.
By: Ziggy on February 17, 2012
I love this gun so much but i really dont like the grenade lancher so dont use it but in other cases it is a pimp M4A1 :) :) :-) I LOVE IT SO MUCH!!!!!
By: Nick on February 16, 2012
this gun is awsome. mine is made of metal. all the bad reviews are lies. i hate it when people do reviews and they dont have the gun.

By: Airsoft Knight on February 06, 2012

By: Steve on December 12, 2011
I like how the people who hated the gun, gave it 5 stars. wtf? It looks decent for the price. the extras make it worth more I think.
By: Jerm on December 10, 2011
this gun is the best ever!!!!!!!!!!!!!!!!
By: Blaze on December 07, 2011
This gun is worthy of five stars and should cost more than it already does. I mean with the fact that it comes with an other magazine and a grenade launcher that works like a shotgun is a homerun for anyone who bought this gun.
By: Hulmut on December 05, 2011
By: Bill on December 04, 2011

awesome gun buy it
By: Black Demon on November 24, 2011
I bought this gun and lost the charger after sevrel wars so it was pretty much worthless,so I went ahead and took it apart and the gun is a fricken fantastac gun if u want to get the job done.accurate,good rate of fire,and the clip holds a but load of bb's.
Over all status:Good gun and cheap
By: Cale on November 24, 2011
Its the best gun i have ever got, and with all the stuff you get it's a great buy.
By: Gray on November 22, 2011
Well this gun is ok If I were u I would not wast your time. If your looking for a cheap gun this is it.

WHOA COOL GUN I WISH I CAN GET IT
By: Beasty on November 21, 2011
best gun ever
By: Evan on November 21, 2011
This gun is plastic as is most other guns under $75.00. this guns grenade launcher shoots 200 fps with .12 and it is helpful when you run out of ammo.
By: Airsoft Expert Previewer on November 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.
By: M16 Assault Rifle on November 13, 2011
