I have a Bighorn TL3 in a MPA chassis running 223 Ackley Improved that runs great. I’d like to replace my MPA chassis with a post 2014 AIAX chassis and am wondering if this action and mad system will run. I was unable to get my MDT 223 mag to engage in my factory AIAX 308 rifle. I’m interested to see if anyone is running this system and having success.
