Our take:  The WE Full Metal M4A1 RIS Airsoft AEG is the definition of high performance.  This M4 comes pre-installed with a 6.01mm tightbore inner barrel, precision reinforced internals, and a high RPM motor.  This AEG has full metal externals with a polymer stock and grip, and features a functioning bolt catch.  Probably the best part of this rifle is the innovative spring-tension release system when switched to safety.  This means that every time you put your rifle into safety, the tension and stress on all of the internals will be released, increasing your AEG’s longevity.  The quality of both the internals and externals of the WE Full Metal M4A1 RIS makes this AEG perfect for beginner and veteran players alike.

5 WE Full Metal M4A1 RIS Airsoft AEG Rifle *****
Rule the battle!

"If you are in the mood to scare everyone on the opposing team... GET THIS! The tight bore barrel is amazing. I am shooting harder and farther than anyone on the field. My only complaint is some slight structural issues, but that might just be my OCD. Overall this is amazing. The build quality is great. You may be thinking, "Great another stupid M4." That my friend is where you're wrong. Are you ready to bring the pain? BUY THIS GUN! PROS: High RPM motor, extremely hard hitting (mine was almost maxing at 487 fps!), Solid and heavy gun (you may want a sling for it), Everything you think would be plastic is metal, great mounting space, adjustable sight, removable sight to replace with optics, metal sling handles, tight bore barrel (6.01mm), You could almost snipe with this gun, loud and a tiny bit of kick for a more realistic feel, where polymers are used they are used reasonably and are very sturdy, bolt catch to adjust hop up, could take a lipo but might need some slight upgrades to maintain it for a longer time if used consistently but I am not sure if you really would need upgrades it is a reinforced gear box. CONS: Stock can feel a little too shaky at times, Burns through a 300 round mag in about 30 seconds or less (this may be good or bad lmao), some structural issues with the receiver the upper and lower part aren't quite tight enough together (this may be fixable with some tightening i just don't know how. Overall not any huge problems just small ones that you won't even notice when you are destroying the other team. Just a little side note, I had a night match and when people turned their flash lights on while shooting, you could see spaces between the bbs being shot... when i turned my flashlight on and shot in full auto it looked like a constant beam of bbs it was shooting so fast it looked like a laser. one more thing the hop up is perfectly adjustable to your sights... you can aim down the sights and actually hit something. Great gun enjoy it!"

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
