Our take:  Military simulation calls for an airsoft rifle that performs at its peak.  But it also entails a rifle that mirrors the most minute detail down to its core.  Enter the MKM AR15, a gas blowback rifle the uses the Force Velocity gas system that delivers commanding muzzle velocity paired with realistic blowback action.  This is the same system that KWA employs in the AKG-74M, LM4 GBBR and its coveted KRISS Vector.  Constructed out of hard anodized metal, this rifle system is far beyond an ordinary M4.  Notably, the rifle’s outer body boasts officially licensed PTS furniture, including a Mega Arms MKM AR-15 billet upper receiver.  A GTR-3H lower receiver also comes pre-installed, which features Mega Arms’ official logo etched on the side.  But the rifle’s main highlight falls toward the aluminum free-float handguard.  Aside from being slim and sleek — allowing for a firm and secure grip — the KeyMod handguard can turn this streamlined rifle into a modular weapon system.  Aftermarket Picatinny rail sections can quickly attach onto the MKM AR15 within seconds.  While the front and rear sights come in handy for most engagements, aftermarket rifle scopes assist in taking down targets in outdoor games.  This is thanks to the rifle’s 18-inch monolithic top rail.  In addition to all the key features mentioned, this gas rifle also sports a replica gas block, enlarged trigger guard and PTS skeleton trigger.

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
