Arthurian Airsoft Excalibur Knight M4 AEG

Arthurian Airsoft has released the ‘Excalibur’ range of AEGs with something for every player. The Excalibur AEGs are all full metal construction with numerous styles of external parts to compliment and individualise every variant.

The Excalibur Knight is equipped with a 7″ 20mm RIS rail system capable of attaching any 20mm accessories. With plenty of rail space and the relatively short front end, the Knight is perfect for CQB. The mock gas block at the front not only acts as a stabiliser for the outer barrel and prevents it from wobbling with the free float rail system, but it also has a folding front sight to allow the user to attach any dot sight or scope whilst having stable back up sights at the front and rear of the rifle. There are 16 rail slots on all four sides of the rail system to allow users to adapt the rifle in any way for their suited style of play.

The upper receiver has the standard 20mm Picatinny rail on the top with the laser engraved ‘T’ number markings which continue onto the rail system. The forward assist, although dummy, still moves back and forth when pressed. A nice design feature compared to some fixed, molded forward assists. The dust cover 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. The thread on the upper receiver is the standard thread size for most rails designed for airsoft AEGs, making customisation of the rail endless.

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 buffer tube is still only 1″ (25mm) long but does feature the E&C (Exchange & Chrono) spring change system, proprietary to the Excalibur series rifles.

The main feature on the stock system of the Excalibur series is the E&C quick change spring system. As seen in the pictures, all you need to do to change the spring is unscrew the ring on the stock tube, rotate the stock tube 45 degrees and pull it off. After that unscrew the knurled screw at the back and the spring & spring guide will pop out. Be careful not to let it fly across the room, it may release with some force. Ultimately, this process only takes about 30 seconds.

The Gearbox:
The gearbox is very well constructed with components you’d expect from most mid-range AEGs, however, the Excalibur series comes preinstalled with 8mm bearings, a 15 metal tooth piston, enhanced tappet plate and of course the E&C spring change system.

This model comes with a battery compatible crane stock, meaning finding batteries to fit the Excalibur Knight are easy to find. If you are unsure of what batteries to use, take a look at the technical specifications for the recommended batteries. The crane stock has two tabs at the back to press in and the back plate comes off, then remove the rear spacer and you can install your battery. The stock is adjustable between 6 positions which extend up to an extra 80mm giving you plenty of choice for a comfortable shooting configuration.
