The range around the corner rents a full auto version. I had to give it a try. I ran two boxes of ammo through it. The model I shot had a 6" barrel and a suppressor. Single shot was very manageable, three round bursts were very easy to control. Full auto it does tend to wander a bit, but not as bad as say a Thompson. It never had any FTF, and the controls are easy to use. It uses Glock magazines.
I give it a 9 out of 10. Unfortunately I don't think that .45 ACP is a good carbine round much past about 30 yards. My opinion, your mileage may vary.
