Last week i took the lock apart on my mtn rifle and gave it a couple coats of birchwood casey Molly lube. Fly stopped sticking and really worked well. Just took the scope of my x-150 and figured what the heck, gave the bolt a couple coats, let it dry and then decided to coat the trigger assembly with a few coats. Put the rifle back together and worked the bolt a few times and it slid slicker than silk, tried the trigger, You feel the tightness and then it just breaks smooth and clean. That Molly lube improved the trigger a lot. Now i just have to wait for the BS bullets to come in and give those a try! Amazing what you find when you just give it a try and see.
