After getting the rifle and BX trigger home and safety checked I measured the pull weight of my stock trigger which broke between 6.2 and 6.7 pounds in 10 tests with my crappy Wheeler spring gauge. I installed and tested the Ruger BX trigger on the same rifle which broke at 3.2 to 3.6 pounds on 10 tests. The pre-travel on the BX is LONG and light and breaks with a "snapping carrot" feel. It basically has all the characteristics of a standard Ruger 10/22 poly trigger group with a lighter break... which is about what the advertising presents in a more marketing friendly way.

So, for $25 more than the value of my stock trigger I got a lighter stock trigger.

So... the Ruger BX was returned, a second Hornet Spitfire was ordered and replaced the stock group in my new 10/22, life is good. It was a $60 net upgrade, the extra $35 over the BX trigger upgrade got me the auto bolt release and a significantly cleaner, lighter and more consistent trigger while retaining the (honed) stock hammer for consistent ignition. I looked at doing one of the drop-in Volquartsen or Kidd jobs, but the cost simply wasn't comparable for the end result or effort required (a minimum of $50 for the VQ hammer + bolt release, $109 for the Kidd drop-in kit assuming you upgrade rather than sell your stock trigger group).
Just figured I'd share my experience for anyone else who's looked at one of these, it's not a bad product but for a few dollars more you can do a lot better, in my opinion.
