Arthurian Airsoft -  Excalibur – Zealot M4/M203 AEG

When you really need to take some fire power out in to the fields the Arthurian Airsoft Zealot has you covered or more to the point you have your team covered with the pre installed M203 grenade launcher. 

The front sight is a fixed ‘A’ frame sight and it uses a standard delta ring, which means you can remove the launcher and replace it to create a standard handguard. It has a barrel mounted M203 grenade launcher equipped and the launcher has a safety and trigger guard meaning that accidental discharge is very unlikely.

The M203 grenade launcher takes the 40mm moscarts which are gas or CO2 powered that fire a bunch of preloaded BBs all at once for a short-range blast

Upper Receiver

The upper receiver on the Excalibur Crusader is equipped with the standard 20mm Picatinny rail on the top, and the usual carrying handle already attached. One thing that makes this gun stand out is that although the forward assist is a dummy version it still moves back and forth when pressed.

Dust Cover

The dust cover on this M16 AEG locks into place and flips down when the charging handle is pulled, this also reveals the hop-up unit. When the mock bolt plate comes back, it locks into place so the user can easily adjust the hop up without having to keep pulling the charging handle back. This can be released again by pressing the bolt stop on the lower receiver.

Lower Receiver

The lower receiver noticeably bears the ‘Excalibur’ logo laser engraved on the left side of the mag well. The bolt release, as mentioned before, releases the locking bolt plate. The fire selector settings are engraved with the standard ‘Safe’, ‘Semi’ & ‘Auto’ setting with a selector switch which clicks positively into place on each firing mode.

The Gearbox

The gearbox is very well constructed with components you’d expect from most mid-range AEGs, however, the Excalibur Crusader comes preinstalled with 8mm bearings, a 15 metal tooth piston, and an enhanced tappet plate.

The Excalibur Crusader comes with a fixed position, and a sliding stockto allow you to get the length of the Zealot to your liking. A quick change spring system is on this platform.
