Ares M45 X-Class AR Pistol Stubby Quick Detach Edition

Product code:
  • Stubby Pistol Style AEG
  • 9mm Style AR Receiver
  • Folding Stock System

This rifle is something special, its the latest AR build from ARES but with a twist: it features a .45 pistol calibre lower receiver and outer barrel setup! Originally created to avoid legal issues in America this trend has fast been sweeping through the Airsoft market, and this is ARES's entry into the foray.

Full description


Designed with quality in mind this weapon features a mix of highly durable alloy with heavy duty polymers, with an Alloy Receiver, Hand-guard, Folding Stock Mechanism and buffer tube, with a polymer pistol grip and stock. Externally the weapon is of very high quality, with a straight edged design pattern to give the receiver its unique look. 

This weapon certainly stands out from the crowd thanks to its pistol style lower, but what might not be immediately apparent is its unique front-end quick swap system. By pulling down the elongated tab at the base of the hand guard you can twist out the barrel and pull out the entire hand-guard assembly in piece. The outer barrel, inner barrel, hop-up unit and hand-guard all come away in a single unit allowing you to build a second hand-guard which can be quickly hot-swapped depending on the game type or situation.

Another major change with this weapon is the inclusion of ARES's new slim line grip system, which is more realistic in width to a real steel weapon, being considerably thinner than its AEG counterparts thanks to ARES's new range of slimline motors. A welcome change for those who are going for realism.

The weapons folding stock is also an interesting change. Traditionally in a folding stock AEG the weapon would have to be front wired, and due to the weapons small size it would not be possible to do this unless you used a PEQ box or battery holder which would ruin the weapons aesthetic. To counter this ARES have developed a contacts system into the stock which are on the rear of the receiver and the front of the buffer tube. This allows the weapon to have maximum storage for battery, and all the battery which you have been using in your other AEG buffer tube should fit in the weapon too.

Just because the weapon features a fancy pistol mag lower receiver does not mean that the replica misses any of the standard features of an AEG. The weapon features a fully adjustable hop-up system for range and accuracy, a top 20mm RIS / RAS rail for attaching sights and scopes, and a four point hand-guard for attaching a variety of grips, bi-pods and torches. The mag release has also been extended with an elongated bar to allow the magazine release to be in the same place you would expect it on any M4 / AR. The stock is also adjustable up to five positions and features the standard ARES AMOEBA sliding stock.

This weapon is perfect for those Airsoft Skirmishers who are looking for a super tiny rifle for use in CQB, for those who want to look like they're following American gun laws, or even for Airsoft Snipers who want a small sidearm which has all the features and functionality of a full size assault rifle.
