ENOUGH SAID! 7/13/2020 ** ** ** ** ** ** Brett Zenor PHOENIX, AZ This trigger seems very nice. Some high quality parts that should last. It has a decent pull weight to the trigger. Everything installed painlessly and was able to do all the trigger checks successfully. I'm still waiting on a couple other parts to complete the build. I can't wait to see how it shoots and does follow up shots. 7/6/2020 ** ** ** ** ** ** KyGunCo Verified Customer Sidney, OH Awesome trigger easy to install 2/22/2020 ** ** ** ** ** ## More from
