Bayonet knife

Unexpectedly, Prapor demands a certain item in return for Fox's gun: a Knife-bayonet for MKb.42H.
== Walkthrough ==
There are only two places to find this knife - you can buy one from Adrenaline for 25000RU or find it in a random stash. It is preferable that you delay the quest until you find the knife in a stash since the rewards from Fox are not that great. 
== Notes ==
* You can skip this quest entirely by just getting the SPAS-12 from anywhere else, such as trading a Slug artifact for a SPAS-12 from Sakharov. However, this exchange is limited to 30 trades, so use your trades wisely.
