Our take:  If you’re looking for an AEG equipped with pre-upgraded internal parts, designed for aftermarket compatibility in mind, and rugged enough to withstand high-stress scenarios, the MK13 Mod 5 Carbine AEG by Apex is leagues above similarly priced AEGs.  Though many intermediate to advanced airsoft players prefer to build on top of a base model AEG, this airsoft rifle already has it all.  Internally, you’re looking at a 9mm bearing gearbox that houses steel gear sets rated for M130 springs.  A quick-change spring gearbox lets you set your AEG up for CQB and field games with indoor limits.  And an impressive electric blowback system is built-in for maximum realism.  When it comes to the externals, a quick glance of this AEG shows that it’s no ordinary M4. This MK13 features an upgraded 10.5-inch free float quad rail perfect for mounting additional accessories, giving it a modern tactical look and feel.  Manual back-up sights are also available in addition to any aftermarket optics.  And a 6.03mm tightbore barrel keeps airflow tight and provides excellent range and FPS.  Other notable features of this M4 AEG include an ergonomic motor grip, sling adapter for single-point slings, and mock metal gas block with flip-up sight.

Battery Charger Recommendation:  Although this fully automatic airsoft rifle comes with a standard wall charger to charge the battery, 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.

4 Apex MK13 Mod 5 Carbine 10.5" Full Metal EBB M4 Airosft AEG Rifle *****

"This was my first mid-high level gun that I have purchased, so as a comparison I've only owned and used dboys, and cyma ak variants. CONSTRUCTION: good, solid build. materials are as described and there is very minimal if any wiggle. As someone who as worked with the real thing I will say I was slightly disappointed in how the weapon was weighted (back heavy) but for an airsoft gun the weight feels good and shouldn't be unwieldy for smaller players as well. (side note, mine came with deformation on the bottom of the but stock, like it had still been too hot when they boxed it, foam was stuck to it and its a little cheesy looking) INTERNALS: Im not a airsoft Tech and don't claim to be, I will say that just from opening and working with the hop up, the internals seem very rouged. FIRING: I got the gun yesterday and cleaned it immediately with silicon oil. I have only gone through the zeroing process with my rifle so less than a mag has been through it. First impressions are that its loud first of all, no question it just fired a bb. not that its bad but its certainly louder than my other rifles. It also hits hard, even with .25s I could tell a difference in the power of this rifle. ITS ACCURATE after about 5 minutes of dialing in my scope and I was hitting 3 out of 5 semi auto shots at a soda can from about 50ft. the trigger response is also good. Pros: accurate, great looks, powerful/fps, lightweight, sturdy build. Cons: back heavy, flash hider is NOT as shown In the pictures (cheesy plastic tip) OVERALL: for the money, its a fantastic weapon. if you want to step your game up a bit from beginner level, and don't have the time to spend on upgrading your aeg. then get this!"

"best gun ive ever had right out of the box. it shot cleanly at 402-407 for me. I havnt had to do any swaps on the internals. the only thing i did change was the stock so I have use a large battery (this is lipo ready). only thing that was bad and why i give this 4 stars is because my ebb did not work whatsoever and i really didnt want to go through the repair process. overall great gun i would recommend it to any experienced player. not for beginners because of the weight and lenght"

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
