D|Boys 035 - CASV M4 Full Metal AEG with Tactical Stock in Blue

The M4 is a relatively modern rifle, with the current US Army version (the M4A1) being 
introduced in 1994, It is a reliable and effective carbine that is IDEAL as a standard service
rifle as it is lightweight, accurate, and can be very quickly modified to suit any role on the
battlefield - The M4/16 platform can be used to make DMR's, Snipers, Rifles, Carbines.. etc.
The iconic shape of the M4 has become the symbol for the modern day assault rifle, it has
featured in almost every war game including the likes of Battlefield and Call Of Duty. It is
not only an immensely popular service weapon but also one of the bestselling sporting rifles
(The AR15 version) ever made. It is even popular in the UK as a sport rifle in the correct legal
configuration.  

Another great rifle from Dboys, and another M4 model, the 3581M is based off a CASV style M4, this
front system is similar in appearance to the S-System M4 style Fore-end, but attaches to the existing
front sight and gas block unit - the lower section of rail also extends foreword further than the S-System
Dboys M4, and is made of full metal. Because of the fact the rail system on this rifle is made to not be 
removed on the battlefield (making it very sturdy). 

The rail system on this weapon is secured in place by attaching to the upper rail of the receiver - this
helps to remove the tendency for M4 rails to rotate slightly by giving it more than one attachment point.
As the foresight is fixed, the fact the top rail is raised up by the rail system really comes in useful - this
allows you to mount any optic you may want without having to ensure it will work with the front sight,
you could even put a full rifle scope on this weapon should you see fit - it will clear the foresight because
of the extra centimetre or so the rail adds. 

As we have come to expect from most of Dboys newer rifles, the body on this is amazingly good for the
price - it is one of the nicer metal bodies that can be found on a cheaper rifle, and should never need 
replacing throughout the life of the weapon. The barrel is solid as any you could find and fits into place
with hardly any give - this is assisted by the fact the rifle has a mock gas tube, some free-float railed
weapons do away with the gas tube meaning there is not that little extra bit of security keeping the barrel
straight. the nylon fibre pistol grip and stock feel great and could easily remain exactly as they are - 
however we all know airsoft is just as much about customising your kit as it is shooting it, and as such
replacement parts will fit this weapon with no issues!

Internally this is using a well build and surprisingly well shimmed V2 gearbox - being a standard V2 it is
100% upgradable and will accept upgraded pistons, gears, springs... the whole deal!

please note it comes with gun and mag only, and does NOT come with battery or charger.
