Speaking of suppressors, I also stopped by the AAC booth and chatted with one of their reps. It was nestled in the "Freedom" booth along with several other brands like Remington, Bushmaster, etc.

I chatted with them about using aluminum baffles and they were very adamant that their aluminum baffles lasted longer than stainless, were lighter, and had better sound suppression despite others' printed numbers. You can write it off as just company propaganda but sound tests I have seen do seem to indicate that shooters perceive the sound from a TiRANT to be less than other brands - despite what the print #'s indicate. Regardless, nice products and the person was very knowledgeable as we chatted suppressor cleaning.
