So I've got a SiCo Harvester 30 and the only thing I don't like about it is the direct thread. Sometimes it works its way loose while shooting and I'm afraid I'll have a baffle strike if I don't notice it in time. I saw today SiCo is making a nano ASR for the Harvester 30. I've never used the ASR mounting system. So are they ok or prone to certain failures? Looks like I can get a single chamber SiCo ASR brake and an ASR Nano for $160 online. Whats the braintrust thoughts on it?
