The new FosTech ECHO AR-II trigger is out! I decided to put it to the test by installing it in both a CMMG MKG-45 GUARD pistol in .45 ACP but also I put it in a Fightlight MCR belt fed rifle. How does this new trigger work? Watch the video to find out! The ECHO 2 is now available through www.coppercustom.com.
