My custom built AR57 using CMMG‘s 5.7 build kit and Aero Precision’s enhanced AR15 platform. The CMMG kit contains simply the BCG and bold (which is available in multiple lengths) and requirs their 5.7 magazines. The rest of the parts are standard AR15 parts.
THIS VIDEO IS FOR EDUCATIONAL PURPOSES ONLY. DO NOT ATTEMPT TO BUILD OR ASSEMBLE A FIREARM YOURSELF WITHOUT ADEQUATE TRAINING. ALWAYS USE FIREARMS IN A SAFE MANOR. TREAT EVERY FIREARM AS IF IT IS LOADED.
Just so you know you can set it to 1-hour duration to save battery! if you need help setting it let us know!
leave your magazines loaded and wait for it. the mags will fail and start unloading themselves.
What weight buffer are you running?
