Some people do have a lot of time in their hands to make some custom airsoft guns. In this video Airsoft V4 tries Sniper Kazu's Bullpup VSR and PDI Bolt Action M4. The bullpup VSR is understandable, but a bolt action M4 might leave you scratching your head in wonder... "At the event 'Airsoft War', I borrowed a bolt action M4 under development from Bullpup VSR and PDI for Sniper Kazu, so I tried to put in a Sabage! Field: MISAKI Sabage (Misaki Town, Osaka Prefecture) Primary: Sniper Kaz Bullpup VSR (Tokyo Marui / PDI)."
