Wow, Chris! That's nice!! Is it stainless? I'm currently using Sheridan springs in my Sniper, but I'm dealing with the soft aluminum one that came stock. It's not bad, but I wish someone would whip something up similar to the worm drive on the Rex kits for Sheridan springs. I get irritated using two hollow locks to keep it locked down. One always backed out on me.
