I decided not to get the IA suppressor for three reasons. Number one - it’s a lot more expensive (over twice the price). Number two- it slows down 147 gr. bullets too much. 147 grain bullets coming out of my 7.75 inch barrel hit a lot harder than any bullet coming out of the shorter ported IA barrel. And number three - the IA suppressor sticks out of the end of the handguard, making it possible to get burned or burn items with it if you’re not paying attention to it.
