To be fair,….
I ordered my HiPoint carbine through guns.com and did receive the discount “free suppressor” code from them….
So I ordered the 5.56 can and adapter,… (the adapter is not part of the promo)
Total plus shipping was $130 for a “free” can….
Plus paperwork and transfer fees… should be about a $250 “free” can…
Regardless, I’m gonna hang this on my 15-22 and abuse the hell out of it! 
Caution. Your giggles shooting suppressed .22 will be deafening. 
My giggles shooting anything I’ve already suppressed have already caused hearing damage!
The .50 is quiet-er…. Still loud AF!
5.56, is as expected like a pneumatic nail gun….
The .45 is a hoot!
All that bs aside, I’d like a dead air RDX22 for my FN502.
I know that everything you post is not about me but this “BOGO” sale seems like a nod in my direction after previous BOGO sales I’ve participated in.
