.22 Caliber Sear Trip Kit for CMMG .22 conversions and uppers
FosTecH's .22 Caliber Auto Sear Trip Kit for the Echo AR-II Trigger: Includes Auto Trip, Anti Bounce Weight, & additional springs. Though FosTecH is confident that the .22 Caliber Auto Sear Trip Kit will work in a variety of different .22 conversions it has only been tested with the products from CMMG and the ones offered on this site. This kit does NOT make your .22 conversion fully automatic. This sear trip kit is designed for you to use the Echo AR-II Trigger with your .22 conversion. If you have any questions, please see the video at echoquestions.com. That video will be posted within the next week so if it is not there yet please understand that this is a brand new offering from FosTecH and the video may take a week or two to have live.
