Our take:  The NEW King Arms FN P90® Tactical Ultra Grade AEG is a one of a kind, tactically oriented Personal Defense Weapon that blows all CQB weapons out of the water!  Manufactured by King Arms and licensed by Cybergun, the King Arms FN P90 features a premium high speed gearbox, a rugged exterior, and authentic FN Herstal trademarks.  King Arms is a premier airsoft manufacturer, renowned for creating top of the line AEGs that are manufactured with intricate craftsmanship and precision internals.

The FN P90 is specifically designed from the ground up to be a modular weapon, with a full metal upper receiver and 20mm Weaver rail system for attaching tactical accessories.  Featuring a compact and ergonomic design, this King Arms P90 AEG can comfortably operate in confined situations, with an integrated angled fore grip and bull-pup configuration.  Though this AEG is designed for CQB environments, it has incredible range and accuracy as well as a hard hitting muzzle velocity!  King Arms’ redesigned gearbox and top-tier internals make their FN P90 AEG suitable for both close quarters and outdoor scenarios.  Unlike most other Hong Kong manufactured AEGs, the King Arms FN P90, licensed by Cybergun, features an industry leading 45 day limited warranty, ensuring that your AEG performs at its best.

Close Quarters Combat refers to fighting in confined, normally urban, spaces; and requires a very different type of weapon than longer range outdoor combat. The King Arms FN P90 presents an effective answer to CQB scenarios with its bull-pup layout, which allows the P90 to have a more compact and maneuverable design and unique trigger mechanism. The King Arms FN P90 is fully ambidextrous, providing a comfortable and easy to use system for any style shooter. The upper receiver is made of a rugged aluminum-zinc alloy, with a tactical flat-black anodized finish and three 20mm rails for attaching accessories.  The Sights on the King Arms FN P90 breaks away from the traditional FN Herstal P90 design, with a more modern rail and sighting system. Instead of being open end sights, King Arms incorporated closed iron sights, integrated into the extended top rail.   The full metal tri-rail system features a high profile top rail which seats securely into the upper receiver.

The King Arms FN P90 is the most authentic airsoft P90 replica to date, featuring fully licensed trademarks and a realistic external construction. Similar to its real steel counterpart, the King Arms FN P90 features a high impact ABS Polymer body and full metal upper receiver.  The Fabrique National logo is imprinted near the faux-ejection port, on the right side of the lower receiver.  Each King Arms FN P90 also features a unique serial number, printed onto high-density aluminum-zinc alloy upper receiver. A birdcage style flash hider comes installed on the FN P90 that shrouds the 14mm counter-clockwise threaded outer barrel, however the traditional P90 metal flash hider can be found on our website. The threaded outer barrel accepts a wide variety of attachments, such as tactical suppressors, flash hiders, or muzzle breaks.

The King Arms FN P90 CQB AEG is built to outperform in high stress, close quarters combat, with a full metal high speed gearbox, and premium internal components.  The King Arms P90 uses a reinforced and improved Version 6 Gearbox, featuring heat treated oil-less bushings and a steel gear set.  The trigger mechanism has been improved upon, capable of withstanding higher voltages and temperatures.  King Arms also installed a high RPM motor, giving the FN P90 AEG an incredibly fast rate of fire!  These features, combined, make the King Arms FN P90 the best P90 AEG on the market, with durable internals that are built to last.

5 King Arms Airsoft FN Licensed P90 AEG CQB Personal Defense Rifle *****

"This gun is perfect for CQC/CQB (take your pick) pros: Good FPS (field only) "ready to play" the only extra thing you need is face protection and BB's. cons: FPS hovers around 375-380 ( too hot for CQC) but you can change the spring"

4 King Arms Airsoft FN Licensed P90 AEG CQB Personal Defense Rifle *****

"This gun is is very impressive. The materials that make up the outer part of the gun are durable and it has a great gearbox complements to King Arms. The FPS on mine is around 387 and it is a monster. The hop up has double nubs so the BBs have equal pressure on either side of the BB to make it incredibly stable. For me it is an extremely accurate gun. The only con i had was that the mounts that held a plate against the gearbox to keep the air nozzle pressed against the hop broke. I just put a washer between the plate and the slide on but plate and it works great. As to the guy complaining about the mag, when you fill up the mag you fill it just below the last set of screws on the bottom of the mag, furthest from the winding mechanism. Then you just wind the mag till it makes a hard clicking noise, and it should shoot all the BBs in the mag without needing to be rewound. I greatly recomend this gun."

fun, but...

"cool gun, lots of fun to play around in the yard and tear cans in half with. The gravity fed clip just causes way too many jams and frequent clip removal for gear winding to be realistly used in an actual airsoft game. Accurate to about 100 feet or so and fps drops to 330-350 with lighter bbs of course, recommending heavier bbs to go for a 400 fps shot but with a PDW you shouldnt really be aiming more than 100 feet or so anyway and dont really need the higher fps. Great for attachments i've got a red dot diamond tac sight on it with both lazer and led light on the side rails. Single shot is horrible on it, full auto is nice but recommend sticking too a three round burst for less jamming issues. Completly ambidexturous for all you lefty's out there."

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
