Our take:  The new Javelin Airsoft Works Full Metal EBB [Electric Blowback] M4 RIS is a high-quality, high performance AEG, designed to mimic the sounds and recoil of a real M4 carbine.  Javelin has long been known in the airsoft community for construction premium performance AEGs with upgraded internals, at a price most airsoft players can afford.  Their Electric Blowback M4 RIS AEG upholds that tradition, with one of the strongest mechanical electric blowback systems on the market paired with incredible power and accuracy.

Equipped with a high-torque motor and metal gearbox, the Javelin M4 RIS EBB rifle has been tuned to deliver 360-380 FPS of power with 0.20g seamless BBs with great accuracy up to 150+ feet!  Unlike other pneumatic blowback systems on the market, the Javelin M4 RIS utilizes a mechanical blowback system, which increases shot consistency and provides stronger recoil.  Each pull of the Javelin's trigger delivers a sharp report and cycles the mock bolt, providing the user with a small amount of recoil and adding to the AEGs overall realistic appeal.

The M4 RIS features a high quality hand guard rail system [RIS], allowing you to easily attach lasers and flashlights.  A receiver top rail also allows for you to mount optics with ease; a standard iron front sight and adjustable CQB (removable) rear sight comes in the box.

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 M4 RIS EBB rifle offers an amazing value that is hard to beat, especially if you're looking for a blowback M4 rifle!

NOTE:  This AEG DOES NOT INCLUDE a battery or charger.  Airsoft Megastore recommends a 9.6v Nunchuck style battery and a smart charger for this AEG.  Click HERE for the battery and charger package (sold separately).

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.

5 Javelin Airsoft Works Full Metal M4 RIS Electric Blowback AEG Rifle *****

"I have had this gun for a couple of months and is great for CQB! I just put a green laser, vertical grip, and you might need a PQ box because the battery sometimes doesn't work in the RIS! -YOU NEED A BUTTERFLY BATTERY UNLESS YOU HAVE A PQ BOX!!!"

The best gun ever made!!!!!!

"i absultly love this gun! it shoots 420fps with a 7.4 Lipo battery and has the greatest accuricy a gun can have. i modified my gun into the AR-15 look buy changeing the but stock. i HIGHLY recomend getting a differnt mag. its really wobbly but that doesnt really matter, go to accesorys and go to mags and get a thermal molded mag, it what i have and i LOVE IT!!!!!!! the battery is hard to get in, it goes up in the frount witch is a total hassle. i would also get a acod or hilogaphic scope, it boosts the accuricy a lot. i use a trigicon acod or something like that, go to the tatical scopes in the accesorys if u want to see my review on it. this gun is accurit up to 250ft tops. ive only shot 3 people at that distance but thats just me. the average shot is prob 100ft or a little less for me. this guns rate of fire is about 20 bullets per sec witch is really good! i will be makeing a youtube vidio on this gun so chek it out!!!!!!! ( i will mention i madified it in to the AR look )"

Great Gun!

"Ok so first off right when you open the box the gun looks great. When i chronoed it, it shot 360 fps and 13 bbs a sec with a 8.4 volt battery. I was hiting targets easily from 80-100 feet. This gun is great for feild and decent for cqb. It is also very easy to adjust the hop up. I havent found anything wrong with the gun yet but if you dont like a little wobble in the mag thats something to think about. Overall its great. verry accurate GET IT!"

Javelin M4 RIS

"The javelin is well constructed with a full metal body and nice 6 position stock. The fps out of the box is a little high, chrono was 420-432 fps on .20 bb's but does settle down after the spring relaxes to typical field speeds of 380-400 fps. The gun is front wired and was a little tight to get a 9.6 v battery in so I decided to go with a nunchuk 7.4 lipo battery that fit very nicely. The gun is amazingly accurate out of the box and reaches the 200-220 ft mark before experiencing large drifting off target. The mag well had alot of wobble which we corrected using the velcro method and had no issues after that running a variety of different mag brands. I ran a 7.4 15c lipo battery in ours putting through just over 10500 rounds before I had my first issue. The electric blow back feature of the gun caused a massive failure of the gear box. Two small metal ears on the blow back mechanisim had broken off and damaged the internal gears and piston. This gave me a chance to check out the gear box where we found 7mm metal bushings, decent gear set *could have been shimmed better*, a very nice anti reversal latch set up *which should be copied by all companies in my opinion* and low resistance wiring. The mech box itself could be beefed up a bit more though and the mech box screws were all loose when we took the gun apart. I rebuilt the mech box and left out the electronic blow back assembly and added some lock tight to the screws. As of today this gun is still running strong and shooting straight... even though I had a bad failure I would still recommend this gun to others. Pro's: Full metal construction, decent fps, VERY accurate, nice range, lipo ready, great looking gun. Con's: Electric blow back poorly designed, loose screws in mech box, mag well too loose, no battery with gun, This is a great gun with some minor issues that need to be addressed. If you buy this gun do yourself a favour and take it apart and check the mech box screws. If they are loose add some lock tight to them. I highly recomend dissabling the electric blow back on the gun."

Javelin M4 RIS

"This gun is all around a great gun for the price but the only thing that sucks is that mine randomly stopped shooting so i have to get it checked out at SS airsoft. Pros: Metal receivers Metal RIS rails Battery housing( in the hand guard which leaves a bunch of room for upgrades) Good velocity Full metal internally Cons: Wobbly stock and charging handle Huge mag well (mag wobbles like crazy) Crappy blowback not as accurate as i thought but still pretty good I recommend getting a 9.6 or a 7.4 lipo battery and a smart charger. this gun MUST use a nunchuck or butterfly type battery. I recommend this gun to a person who has recently started going to actual airsoft fields "

The store is amazing. I have found there items that I could not find in other stores which makes it the best. I have made questions and inquires about products and the customer service has responded super fast with accurate answers. All my products have arrived in excellent conditions in spite of other stores. My last product came late because it was rescheduled but that was UPS fault I think. I would like to thank Matthew for his exceptional customer service. Whenever you need help, please try to contact him. My advice, buy in Airsoft Megastore, they have coupons and the widest variety of airsoft products. RandyLoy, USA
I ordered a gun sling a couple weeks ago. Unfortunately, one of the clips broke. After a few email correspondings with a customer service representative named Jun (my emails did not show a last name), AMS sent me a replacement sling for free. I did not even have to send my clip back. AMS is a terrific store and I plan on doing more business with them. They were polite, efficient, and just a pleasure to work with. I would recommend Airsoft Megastore to anyone. mskanwischer, USA
Airsoft Megastore is The Best Airsoft Website Out There (I Think) and i Will Always Be Loyal to AMS and Order Almost All of my Gear From Them. The Customer Service is Also Amazing, Jun my Customer Service Representative Has Helped Me With Anything i Needed Help With, Especially My Order Problem (Had 2 Magazines Missing from Order) and Jun Helped Me With The Problem, and Now The Mags Have Been Shipped To Me. Thank You So Much AMS and Jun. Ethan1214, Saskatchewan, Canada
I love that Airsoft Megastore has videos of most any information you will need to learn and care for your products. I purchased an AEG for my son and in short order, unfortunately, it began grinding after brief use. I emailed for warranty repair with symptoms and with 24 hours (22 to be exact) I received an email explaining possible causes with a video like for tuning the gun. I had the gun working again within 15 minutes, avoiding returning the gun and the mess associated with returns\repairs. Excellence on Sean's part to help out a first time customer of theirs. Highly recommend. bucfanjeff, USA
Everything worked great, shipping was super fast. I am very pleased and won't hesitate to order through airsoft megastore again. rob_riley, USA
