Umarex has released yet another Legends Replica Airgun and perhaps this one may be the most iconic yet, the M3 Grease gun with a history as far back as 1942. It was put into service int 1944 and then the later variant the M3A1 was used in the Korean War. Also make sure to watch my Table top Video for it for specifications and details along with more close up video.
Getting back to the Field Test Review for the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun, as always I like to test each gun out in the Replace Airguns Indoor Sea Can Airguns Range first placing 5 rounds through my Chronograph to find out the real world velocity of each test gun, then I shoot 10 rounds in semi auto at a distance of 30 feet onto a paper target to see how tight of a grouping I can get shooting from a seated and rested position. With full auto Airguns I like to then perform a full auto shooting test to see how it groups in full auto as often times the full auto grouping will open up somewhat as some Blowback Full Auto Airguns do tend to move around a lot more in full auto mode.
For my Power or Velocity test I was using dual brand new CO2 cartages. Umarex does state that the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun will shoot around 450 fps and with my 5 shot test I was able to confirm this and get close to this mark averaging 436fps. The temperature in the Sea Can was around 20 degrees Celsius or around 70 degrees Fahrenheit. Perhaps in warmer conditions I might hit the claimed 450 fps but I was close either way.
For my accuracy test I setup a new paper target 30 feet downrange and proceeded to place 10 shots into it using the peep sight on the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun. I was fairly pleased with a fairly tight 1.5 inch grouping in semi auto. I then switched over to full auto fun mode and with the remaining BB’s I unloaded 50 or so rounds in very short order and as expected the grouping opened up to closer to a 4 inch grouping. This was kind of expected since the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun uses an open bolt system which has a fairly heavy bolt which makes the blowback action more intense, similar to the KWC Mini Uzi but to a lessor degree.
Any time a company puts out another Full Auto Replica Rifle, especially full auto firing, I am 100% in on it. Both Crosman and Umarex have done a great job doing this and the Umarex Legends CO2 Blowback Full Auto M3 Grease Gun is another example of a well thought out and what I expect to be very popular Full Auto BB Rifle. Their Legends series encompasses guns of the later era which I personally really like since they are harder to come by in their real steel versions, so having them available in an easier to acquire version that you can even shoot in your back yard is a win win for everyone. I am also happy to confirm the high capacity double stack 60 round magazine seemed to feed pretty good for me only miss-feeding once during my testing while doing the Chronograph portion but it got back on track right away. If you’re into Full Auto Legendary Airguns then for sure pick one up from us!
