I used this for half the season of one indoor league and don't have the time to shoot anymore. Works as a backtension or trigger release. It's in original packaging, spring kit never opened. This is like new. Paid $200 need $150. I have just listed on Craigslist and Ebay as well. Call or text me at 815-761-7217 Thanks Chris . I live in Stillman Valley, work in Cortland, can also meet you in Rockford if schedules line up. Paypal OK.
