The X320 soon to be renamed the M320 (X is taken away since it is no longer an experiment) It is a single shot 40mm grenade launcher to replace the M203.Through a competitive bidding process, Heckler & Koch was awarded a contract to provide the XM320 beginning in 2006.
The XM320 has a pistol grip in front of the trigger, unlike the M203 where the magazine functions as a hand grip when firing.
Like the M203, the XM320 attaches to the M16 assault rifle and the M4 Carbine but is also capable of attaching to the developmental XM8. Both attach under the barrel forward of the magazine.
The sights on the XM320 are located to the side of the launcher. This avoids the problems that the M203 had with its sight design: (i) sights mounted on top of the rifle interfered with the rifle's sights, (ii) sights were attached separately, resulting in two separate operations when adding the grenade launcher to the weapon, and (iii) because the sights were not integral to the M203, they had to be re-zeroed every time the launcher was reattached to the rifle.
The XM320 can fire all of the high-explosive, smoke, and illuminating grenades previously fired from the M203. However, because its breech opens to the side, instead of the pump-style of the M203, the XM320 can also fire a variety of newer rounds which are longer, specifically certain non-lethal rounds.
The XM320 operates in double action mode, with an ambidextrous safety. The M203 used a single action mode which was cocked as the breach was closed. In case of misfire, the XM320 operator merely has to pull the trigger again, versus the M203 operator who has to cycle the breech to re-[TOS Violation] the firing pin, then pull the trigger again.
What are your thoughts on this?
I Might think as it replaces M203, this would be in graw?
