Took my MP7 out to skirmish today at Firefight Reading. I was blown back by the range and power of the thing, it easily matched my GBB and my mates mk23 SOCOM, and is just a tad under the power of my MP5!
One thing it needs is bigger mags! 50 rounds isn't enough for a firefight, 100 would do the trick nicely! Decided I need a couple more mags though
