Here we have a BNIB, unmarked, seemingly unused MP5K from Maruzen in its original box with paperwork.

This was stored as new, presumably in a loft or a shed for some time, and the outer cardboard of the box has been exposed to damp at some stage, as can be seen by its condition but luckily there is no evidence of corrosion to the rifs metal parts, though the magazine which was stored separately does have discolouration on its surface, but is solid, working and gas tight. 

There are no signs of use or wear or any scratches anywhere on the rif. I'd recommend a barrel and bucking clean before use. 

I waited for the recommended 144a maintenance gas to arrive before testing, as these rifs are not designed to run on green gas, which can cause damage in the long term. The MP5K works well on both semi and full auto, with a blistering rate of fire on full. I dont think any other airsoft standard factory MP5K has this rate of fire.  

The famous HK slap shouldnt be done on this plastic rif as it will cause damage, and I havent done it. You can merely pull back the cocking lever and let it go again. The slap shouldnt really be done with other airsoft rifs either, as they really are mostly pot metal and plastic and prone to breaking easily.

The MP5K comes in its original box with polystyrene insert, an instruction booklet, an advert for the CA870 shotgun, a Japanese form in triplicate and a small bag of BB's as it tradition but shouldn't really be used.

I translated some text from the manual about the hop, which is fixed and BB range should be set by choosing a suitable BB weight starting with the recommended 0.2. 

This RIF would suit CQB play or as a PDW for close work, or just to keep in original, pristine condition as a cabinet queen? (to stop the dust)
