This model is part of the Arthurian Airsoft Excalibur range. There are several different models available, but the AEGs are made fully from metal, with a variety of external parts to complement each individual gun.

The Excalibur Crusader is the heaviest and largest model of the Arthurian Airsoft Excalibur range of AEGs. It was named after soldiers from the religious crusades spanning from the 11th to 13th century. The term ‘crusader’ has been used to refer to tanks, jets, military operations and now this M16 AEG.

The outer barrel of this M16 AEG measures at 19″ with a 500mm inner barrel. 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 solid stock giving you plenty of battery space in the rear. Although this is the same as the Veteran model, the Crusader is installed with a quick-change spring gearbox.
