Arthurian Airsoft Excalibur Knight M4 AEG

The airsoft rifle is part of the Arthurian Airsoft ‘Excalibur’ range of AEGs. There are several different models within this range, and something suitable for every player. The Excalibur AEGs are constructed fully using metal, with the option to add external parts so you can personalise the gun.

This gun is an impressive and intimidating weapon. The Excalibur Knight is equipped with a 7″ 20mm RIS rail system, and you can attach any 20mm accessories. There is plenty of rail space on the gun and the relatively short front end makes the Knight perfect for CQB.

There is a mock gas block at the front of the gun and this acts as a stabiliser for the outer barrel. It prevents the barrel from wobbling 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.

The left and right sides of the rail system come bare, but you can easily attach the LVOA type rail segments. The top already has an integrated 20mm Picatinny rail with the numbered ‘T’ markings laser engraved on the rail slots. The gun length is between 704-784mm, with an outer barrel length of 10.5” and an inner barrel length of 249mm.

You have the option to change between fire selector settings, with choices standard ‘safe,’ ‘semi’ & ‘auto’ settings. The buffer tube is still only 25mm long but it features the Exchange & Chrono) spring change system, proprietary to the Excalibur series rifles.

One of the most impressive features of the stock system of the Excalibur series is the E&C quick change spring system. To change the spring, you simply need to 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.
