Our take:  The NEW Full Metal Gearbox JG M4 RIS CQB Rifle is ideal for both indoor and outdoor airsoft games.  Featuring a hard-hitting muzzle velocity, carbine length full metal outer barrel, and a precision inner barrel, this AEG can easily take down targets at over 125 feet!  JG's newest addition to their line of polymer body M4 AEGs features a complete hand guard rail system, perfect for mounting aftermarket accessories such as optics, lasers, and tactical flashlights with pressure pad!  Weaving through confined spaces is made easy by this compact carbine's retractable stock, allowing you to clear rooms with ease!  This polymer body carbine comes with the newest JG Version 2 full metal gearbox and can shoot up to 400 feet per second (0.20g BBs), making it a perfect primary weapon for medium to long-range engagements!  This M4 AEG performs at the same level as full metal M4s which can cost nearly twice as much, and is perfect for players looking to step up their airsoft game!

Thanks to the full metal quad rails, this M4 RIS serves as a perfect platform to add aftermarket accessories like PEQ boxes, tactical fore grips, flashlights and laser units.  This M4 RIS comes fully equipped with a functional charging handle and bolt release, adding to its overall realism.  Racking back the charging handle kicks open the dust cover and locks the mock bolt to the rear, allowing you to easily adjust the precision one-piece hop-up chamber.  Pressing the bolt release slams the mock bolt home with an authentic sounding "Snap"!  The M4 rifle is also equipped with metal sling mounts and retractable M4A1 stock, improving the overall ergonomics of this AEG rifle.  The JG M4 RIS features a unique battery storage area, located inside of the included fore grip, with enough room to fit a small type 8.4v battery.  This unique battery storage area makes swapping out batteries easy, and keeps the carbine's profile streamlined.  Ready to go right out of the box, this JG M4 AEG includes everything you need to start using the rifle on the airsoft field!  If you're looking for a hard-hitting M4 RIS AEG that is under $200, then this field-ready airsoft CQB rifle is perfect for you!

Package Includes: Rifle, 300-round high capacity magazine, battery, charger, tactical fore grip, 2x Rail Covers, instruction manual

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.

JG M4 CQB Review

"I have used this gun for over a month and have had no problems. I use it on outdoor and indoor games and it rocks! BUT The battery is in the forgrip so it can only fit the 8.4. The center ring that locks the rails wiggles making the gun feel lose but does not effect accuacy. Loads of rail space to custom this gun anyway you want. good ROF and tight grouping [the size of an orange] when at 75 ft. i have 3 AEG's 2 JG's and a CYMA and i have to say this is my fav now. I put a red dot and a 5000 round mag. on it, now its a beast."

Really Awesome, I recommend

"So I got this gun about a month ago and it works really well compared to any of the guns i have ever had. Some pros is that the fore grip is really comfortable and the range is far and accurate. Another thing is that the battery goes into the fore grip so you haft to have the fore grip on at all times to use the battery and some people find that weird but i don't care. The gun is mostly polymer but it is strong an the rails is where all the weight is because they are solid medal. Some cons is that the charger doesn't work. That could be just my package but o well what are you going to do. i got a smart charger anyway. Another flaw is that the battery doesn't fit to well in the grip, the structure is fine but there is this thing top that covers but it gets in there fine. The rails are wobbly but i don't take much notice to it. So i like the gun a lot so if your getting this gun its is fun to to have and use and i hope this review was helpful."

Best in Class Customer Service

Same Day Will Call Pickup

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
I loved buying from airsoft megastore because the employees helped me recover my tracking number and told me where the package was at, I would love to buy from airsoft megastore again! Battlefield4Rule, USA
