They are especially fun with supressors. Get the tri lug adapter and it's the most fun you can have with your pants on. Totally silent and zero recoil.

You'd need to SBR it and get a stamp if you want to put a stock on it, which you do want to do. But it's worth it.

I don't know much about MKE but i think they are generally pretty good. I know the Zenith guns are very good HK clones and the MKE aren't far behind.
