Barrel: 9 inch Metal non-rifled. Propulsion: CO2 x 2 (housed in b uffer tube) Action: Semi and 6 round burst blowback, single action only. Ammunition Type: 4.5mm BB's. Ammunition Capacity: 900/30 round drop out hopper/magazine. FPS: 400 The Umarex Steel Strike CO2 BB Rifle looks to be an improvement over the Steel Storm and Steel Force, I like the new placement of the duel CO2 into the buffer tube and changing the location of the BB’s from the upper receiver and into the drop out magazine which is where we would normally expect them to be. We also get a magazine hopper capacity of up to 900 rounds with the new Umarex Steel Strike CO2 BB Rifle so no having to refile int for several CO2 swap-outs. I think the overall looks ahed improved and the tighter aperture of the pep sight shoudl make getting BB;s on target with more accuracy a bit easier. I look forward to seeing what kind of performance I get out of the Umarex Steel Strike CO2 BB Rifle when I test it out during my upcoming Field Test Shooting Video.
