Our take:  Madbull has become a leading innovator in the airsoft industry, designing unique products to maximize the performance of a wide variety of airsoft guns.  Their NEW Madbull Ultimate 3-in-1 Hop Up Chamber is a prime example of Madbull's technological approach to airsoft performance upgrades.  Unlike common M4/ M16 AEG hop up chambers, the Madbull Ultimate hop up features a large perpendicular adjustment wheel which allows you to easily access and precisely adjust the hop up.  This hop up chamber also features a BB retention O-ring, which prevents excess BBs from spilling out of the hop up chamber during reloading.  Another innovative feature of this hop up unit is its compatibility with Madbull's accessory LED tracer unit (not included).  This tracer unit installs onto the hop up chamber, eliminating the need for a bulky mock suppressor tracer unit on the front of your AEG.  

This hop up unit is extremely easy to install and comes with all necessary hardware components.  As an added perk, Madbull has included a Shark hop up bucking and a hop up spacer.  These additional upgrade components make the Madbull Ultimate Hop Up Chamber and incredible deal!  This performance hop up chamber is in high demand, so get yours before they're gone!

Madbull's 3-in-1 Hop Up Technology:
1) Compatible with Madbull's accessory tracer LED unit, turning this high quality hop up chamber into a functional tracer unit
2) Madbull's BB retention system prevents excess BBs from dropping out of the hop up chamber during reloading
3) the hop up chamber's perpendicular hop up adjustment wheel allows finely tuned adjustments, and doesn't slip out of place during skirmishes

Construction:  Full Metal Alloy
Compatibility:  Fits most M4/ M16 Metal Gearbox AEGs*

* Fitment of this hop up chamber is not guaranteed for all M4/ M16 AEGs.  Be sure to check if your AEG is compatible BEFORE purchasing this hop up chamber.  Some modification of this hop up chamber may be required for proper installation.

NOTE:  The BB retention feature of this hop up chamber will keep BBs in your hop up even after the magazine is removed.  This means that the gun is still loaded even with the magazine ejected.  Remember to always properly clear your airsoft gun's chamber before exiting the airsoft field, and to always treat your airsoft gun as if it were loaded.

Package includes: 1x Madbull Ultimate Hop Up Chamber w/ all necessary components, 1x Madbull Blue Shark Hop Up Bucking, 1x Hop Up spacer, instruction manual

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
