Is it legal to buy binary trigger in a pistol AR?

[bunker buster]

I plan to get a pistol brace AR in 556 with binary trigger is it legal in MA?

Maybe? 10 rds at a time, from a fixed magazine, unless you have a pre-ban pistol. I think we only wrote bump stocks and trigger cranks into the law so far. (IANAL)
