So I was invited to a shooting afternoon in north Georgia this past weekend, and had a chance to shoot an FN P90...5.7x28. among other items (hk MP5, HK MP7, 1919 in .308, m16, m4, ak22, and others)and i must say, it was fun, fun , fun... it has almost no recoil. it shoots pretty darn accurate, is compact and solid, even with the plastic mag.it comes with a red dot. and we had it cero in at 100yds. it fires super fast, 50rds mags go really quick. And the empty shell just drop from below. so it can be shot left or right. . we shot at metal targets at 50yrd and 75yrd and some orange cones elevated to about 10ft. I wanted to test the effective range.i managed to hit some targets. W also had some old refrigerators , washers, empty gas tanks and stuff at a much closer distance. It is a true pleasure to shoot it.
