Sound Signature Review 6.217 – The CAT ST on the 14.5-in M4 midlength gas AR-15. New CAT rifle silencer using their SBX technology; a little different than SURGE BYPASS. How does their universal 5.56 silencer stack up? Well, it’s not normal, apparently. Intro discussion for today’s report. (00:47:55)
Sound Signature Review 6.218 – The CAT AKB on the 14.5-in SR-25. Another new CAT rifle silencer – this time a universal 30 caliber model. Different and smaller than their ODB. This one seems to be at home on everything from subsonic things to a battle rifles… we’ll tackle the intro for that report today as well! (01:01:08)
