From my experience with the demilitarized semi only version that I own; no bump stock is needed, hold it limply enough and try to slowly squeeze off a shot, it’s gonna bump fire haha.
I like that patch, I shouldn’t, but oddly I do.
Here's the deal with FAL's - they are fairly heavy and long. Tavor makes a 308 bullpup which is much lighter and far more compact. There are even better 308 bullpups out there like the one made by K&M. When it comes to .308 - a bullpup is the way to go.
