BB2K Airsoft checks out the other realistic action airsoft shotgun in the market, the Dominator International DM870... "Pumpaction Time: Today I unbox for you the DM870 Shotgun from Dominator. The completely made of solid steel pump action shotgun brings so much fun and long playfulness is inevitable. Whether the shells of the cheap PPS M870 and the Madbull CO2 shells fit, I've tested the same time. Have fun."
