Slap a 20 round drum on it and dump the load.
Nothing can describe it.
You’ll probably get walked back 5 feet but it is very controllable.
I have a drum, and some Saiga 12's, just not the model I bought in Vegas.
I also bought some things Bulgarian with milled receivers, which is weird cause I swore I'd not do that. They also were purdy. Oh, no, I just remembered I also wanted something from the Walther booth.
