how do you know the kit is stolen? Some of the sellers are offering VAT reciepts, which means strangely enough that they are VAT registered i.e a business.
I would imagine that this means that the equipment is freely available on the open market. Do they come with the crypto fills? probably not and I would imagine that the Russians, Chinese, Americans, Eskimos and other foriegn powers already have this kit and are hardly likely to need to buy it on e-bay. Also naughty people in Iraq probably have this kit also (stolen from camps, lost on patrol, left behind in abandoned vehicles etc..)
"Initially supplied to the British Army under the BOWMAN programme, the
PRR is now in service with approaching 30 nations world-wide. Nearly
200,000 units have been produced of the current model and the company is
now exploring further developments of the system and increases in capability"
I was fairly pole-axed by the amount of British military kit that was being flogged on Ebay last year, so I did some digging. It appears that the Disposals side of the MOD get rid of this kind of stuff (yes, BOWMAN aswell) on a regular basis and it is damn difficult to track through the system. Having said that, there is a certain Staffy at CCRIO who has been tasked to monitor what was being flogged (mainly NVGs/sights etc) and act accordingly.
Despite what some may feel, this problem costs the tax payer (i.e. you and I) a hefty whack per year (one young Guardsman was flogging his whole TELIC kit entitlement and his OSM until I asked his RSM to have a wee chat with him). Also check out the amount SA80 weapons parts that seem to appear for sale every now and again.
