The one everybody has been waiting for, my Field Test Shooting Review Video for the Umarex Legends MP 40 Blowback CO2 BB Machine Gun!
I was originally planning on working out some of the magazine feeding issues with the Umarex Legends MP 40 Blowback CO2 BB Machine Gun as other reviewers had mentioned that the steel 4.5mm BB's can jam up a bit in the magazine. The only thing I did with my Umarex Legends MP 40 Blowback CO2 BB Machine Gun was to add a little bit of dry Jig-A-Loo lubricant to the magazine feeding track and make sure all my BB's where properly double stacked.. Other than that my Umarex Legends MP 40 Blowback CO2 BB Machine Gun is stock with no magazine spring mods.
I did find that my RWS Zinc coated Steel 4.5mm BB's had a tendency to bind a little in the top part of the magazine where the BB's go from a double stack to a single stack configuration. Now my RWS 4.5mm BB's are a bit older and I have found that older Zinc and Copper coated steel BB's will corrode a little which could cause some friction problems.
So for my Shooting Field Test I selected some brand new Umarex Zinc Coated Steel BB's and they did seem to work a little better for me as I did not get any magazine feeding issues during my testing of the Umarex Legends MP 40 Blowback CO2 BB Machine Gun. I did notice that when I did a magazine dump that the bolt cycle started to shorten up due to some cool down effect causing the bolt to lock, a quick 5 second break and she was good to go again to finish off the mag.
In terms of feet per second velocity Umarex claims around 450 fps for the Umarex Legends MP 40 Blowback CO2 BB Machine Gun, this may be possible with brand new CO2 on a warm day but I got closer to a 400 fps 5 shot average under normal testing conditions, this is perfectly fine for a blowback BB airgun.
When I performed the accuracy test from my standard 30 foot out position on paper targets I got a very tight 1 inch group shooting in semi auto. just a light bit high and to the left but very close to the center bullseye. When I opened up and went full auto the group did largen a little since the Umarex Legends MP 40 Blowback CO2 BB Machine Gun does rock a little back and forth with it's internal bolt blowback operation but the remaining 40 rounds did stay within the most part within a 2-3 inch grouping.
The Umarex Legends MP 40 Blowback CO2 BB Machine Gun is a really sweet air riffle with a legendary look, blowback operation, semi and full auto capability, decent fps, great accuracy and at the end of the day is simply a ton of fun to shoot!
