Our take:  The new Javelin Airsoft Works Full Metal EBB [Electric Blowback] M4A1 is a high-quality, high performance AEG.  It is one of the most affordable blowback M4 Airsoft rifles on the market (most of the blowback M4s currently on the market are gas-powered, not electric) and performs on par with a rifle of this caliber.

Equipped with a high-torque motor and metal gearbox, the Javelin M4A1 EBB rifle is a high quality, high-performance Airsoft AEG that has been tuned to deliver OVER 400 FPS of power with 0.20g seamless BBs with great accuracy up to 100+ feet, all the while with realistic blowback action that kicks the ejection port open each time to deliver a satisfying 'clink' with every shot.  The power combined with the electric blowback makes this rifle a PHENOMENAL all-around performance AEG!

The unique 5-point retractable rear stock features integrated rails for easy accessory attachment, and also has a special storage compartment which holds up to 2x CR123A batteries (for back-up use in your optics/tactical lasers and flashlights).  The Javelin M4A1 EBB rifle offers an amazing value that is hard to beat, especially if you're looking for a blowback M4 rifle!

Specifications:
Operation:  Electric Automatic, Electric Blowback
Build:  Full metal body, full metal gearbox
Firing Modes:  Semi-automatic and Full-automatic w/ BLOWBACK, with working safety
Muzzle Velocity:  390-410 FPS with 0.20g BBs
Magazine:  300-round high capacity (gear wind-up)
Gearbox:  Full metal
Hop-up:  Adjustable
Weight:  7.5 pounds

Ammo type:  Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs.  For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.

Package includes:  Rifle, instruction manual, 300-round high capacity magazine

Battery Charger Recommendation:  Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery(overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly).  Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly,also automatically shut off once the battery is fully charged to avoid overcharged batteries.

Amazing

"I got this gun a few weeks ago and its great i highly recommend this if you like m4a1's i have had no problems with the blowback never jams and the only bad part is the mag its very loose but with a little tape its fine and the best battery for this gun is an 8.4v nunchuck/butterfly battery because 8.4v mini is a pain in the *** to put in. and this gun does not come with a battery"

Battery answer

"This gun is fantastic! I got it in the mail today, and it is a baby eater! Pros: Chick magnet Extreme rof Higher than expected fps Came with a battery( at least mine did ) Nice sturdy construction Cons: Magazine well is loose as all get out Not a 14mm ccw thread( my jg tracer unit did not fit on the end of this gun due to this.) Over all a great gun, but if you want anything attached, get an adaptor"

"the battery is a mini crane stock type battery it's an 8.4v but only 800mAh. so it wont last you that long. i would go ahead and upgrade the battery and charger to the 9.4v 1600mAh crane stock battery with smart charger for $59.95. that may be the best bet for you. hope this helps"

Pretty Good

"I just got this gun today and immediatley noticed that the gun is well made. But the whole 1000 rounds per minute thing is not true. Mine shoots 850 rpm. The fps is just under 390. This is all with a 9.6 volt battery. And the Mag well is very loose so i would get some electical tape and do like 2 layers. Overall, this is a good gun. It just frustrated me at first because the mag was a bit broke. Get it if you want to kick ass in your local woods against your friends!"

javelin m4a1ebb

"This gun shoots good with a 9.6v I took it to a game with my team and they liked the performance. The gun chronoed at 370 with .20 so it doesnt shoot 410fps and the rps was about 15.6 so its about 936rpm. They tested it with a 11.1 lipo and used 12 bbs i think. I recomend getting a 9.6v because it runs out of juice very quickly. The blowback is cool but a waist of battorie. The mags are so loose that you have to put about 3-5 layers of duct tape in order to not wabble. When i bring this to a meet i get alot of questions about this gun because of its high rate of fire. I think this gun has the highest rof compaired to other aeg. I would recomend you spending 20 more bucks and getting a hybred ak/m4 or something lipo-ready. And my fuse blew in the first shot or two Pros: Very durable Great sights Good weight Just your arvage m4a1 Cons: Not very good range even with 370fps Bad mag insert 370fps chronoed .2 610 shots per min with a 8.6 Not compatable with most upgrades"

simple fixes...

"good gun. i would recommend taking off blowback.(its just a peice of metal riding the piston). and getting new body pins, metal 7mm bushings, and new spring guide. also some duct tape around the mag because it doesnt fit as it should. but with a few simple fixes its great! shoots fast, far, and accurate. i would also recommend wiring to the back with a crane stock and changing handguards (mostly for looks). also the battery that comes with the gun is a 8.4v 800 mah crane stock type. (get a better battery). but for the awesome price, GET IT!"

New players say its good

"This Aeg is really bad i took it to a field and it worked good but when i took it again it stopped firing and the the aegs gearbox was destroyed...... :( If your gonna pay this much money for a company that isn't know to be good i would get KWA or a G&G Mod 1 or 2 or something. On Airsoftgi the Javelin guns are 85 bucks because they had so many returns because they suck. I used good BBs and took care of it so i would not recommend the gun the best use for it is parts. Pro: full metal good for parts Cons: Everything else"

Not Good!

"This gun really let me down! It has almost a full plastic gearbox system and I have had to get it sent off and repaired 2 times already, and it still is not working correctly! The fps shoots around 400fps with a fresh battery, and 0.20 gram bbs, but the gearbox is still plastic! The battery fuse broke on it, and it also had some plastic peices break in it.....and i have spent a lot of money trying to repair this thing, and now it is shooting double and triple bursts on single fire.....and my warrenty is out.....and last but not least,.......just about no other magazines fit in this thing.....no good!"

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
