Installed it in my SCAR 17 to test the trigger pull vs Timney, I'm sticking with the Timney since I prefer single stage.
Never used to fire a single round. Comes with everything (bag, instructions, etc).
Sorry no trades.
I'm camping with the family Friday afternoon - Monday, please post here is you want it and I'll hook up with the buyer Monday evening or Tuesday morning.
