We get to see the P90 Gas Blowback from Cybergun, OEM by WE Airsoft in this BB2K Airsoft review... "The FN P90 has a very special design, which is immediately noticeable. The short compact Bullpup with overlying magazine can be operated on both sides, offers a capacity of 50 rounds and thanks to the special caliber 5.7x28 it is strong enough to go against modern protection. WE has accepted the P90 and delivered the first GBB version. FINALLY!"
