One of the most common weapons we are asked to provide storage for is the H&K G36. The G36 followed a very interesting effort by H&K in tandem with others to produce a rifle using caseless ammunition (the G11). Dynamit Nobel designed some solid propellant which was heat resistant enough to overcome many of the traditional objections to this idea. In the end though, the cost of the G11 was high and so the project was scrapped and a replaced with a more conventional design.
After the initial order from the Bundeswehr it is interesting that the first wide scale deployment of the weapon was for the Spanish armed forces.
Of course, these days the weapon is now widely in use by both military and police in many countries around the world.
The G36 also formed the basis for the (eventually ill-fated) modular XM8 rifle which was developed as a result of an initiative by the US Army to replace the M16 and M4.
FWS weapon racking, of course, easily stores the G11, G36 and XM8 weapons! It actually demonstrates the future-proof nature of our racking that 3 design phases of a weapon spanning 30 years will all fit into 2 standard components that we produce.
