The R603 is constructed with an Alloy Slide and Frame, which gives it a realistic weight and makes it very tough. The Pistol Grip covers are Polymer as you would expect, but have been Stippled to provide excellent Grip even when wearing Gloves. 

The Flared Magwell Extension Piece makes for much faster reloads, helping to guide the Magazine into the right position, and can be removed if you so wish.The Barrel of this Pistol is Threaded, and offers an 11mm CCW Female Thread, which will accept certain Suppressors, or a Thread Adapter to take 14mm CCW Muzzle Devices. Underneath the frame you will find a 20mm Pistol Rail which can be used to install an accessory such as a Torch, Laser or Mini Grenade Launcher. A Beavertail Safety sits on the Pistol Grip, and won't let the Pistol fire unless it is being gripped properly. 

There is also a Slide Lock Safety at the rear of the Slide, which will stop the Pistol from operating when engaged. The Extended Magazine Release is threaded, allowing you to install extension plates if you want a larger button. The Pistol features an Adjustable HOP Unit, which is accessed by removing the Top Slide completely. To do this, line up the smaller cutout on the Slide with the Slide Release, push the Slide Release out completely and pull the Slide off the Frame forwards. Reverse these steps to re-install the Slide. 

The HOP Unit will apply backspin to your BBs, and by using heavy BBs (0.25g+) and the correct settings, you can theoretically improve range and consistency. The Top Slide features traditional Ironsights, but the Front Sight Post has a Fiber Filament that enhances light and makes the Sight Post easier to see in the dark.

Included in the box is a 28rnd Gas Magazine, a User Manual and the R603 Pistol itself. If you're looking for a snappy and responsive Hi-Capa Platform that is made to a tough standard and can have a Red Dot Sight installed, then the Army Armament R603 is a good choice.
