For those who are not aware, Ruger has released a drop-in upgrade for the stock 10/22 trigger group - the Ruger BX Trigger. The packaging indicates the drop-in Ruger BX-Trigger will provide a 2.5 - 3 pound pull and is a complete, drop-in solution (remove action from stock, pop the two trigger pins out, remove old assembly, insert new, insert both pins, reinstall stock - done). MSRP is $89 with a street price around $20 cheaper. I recently purchased one of the Ruger Anniversary Contest Winner 10/22's and noticed that Arnzen also had the new Ruger BX triggger in stock. I don't like DIY trigger jobs, so for $75 (with tax) I figured it was a $25 upgrade if I sold the original trigger group for $50 so why not.
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. It looks just like the recent polymer trigger groups including the extended magazine release, but DOES NOT include the auto-bolt release modification.
So, for $25 more than the value of my stock trigger I got a lighter stock trigger. Not a bad investment... but when I compared it to my drop-in Hornet Spitfire-S trigger group which is a $60 upgrade I noted the following differences: Auto-bolt release is included, which is a $10 value. The Spitfire trigger group upgrades the stock pins and does not allow it to "wobble" side to side like both Ruger triggers. It has a shorter, cleaner pull thanks to an upgraded trigger, sear and disconnector plus a much cleaner travel & break at 2.75 pounds which only varied .2 pounds when measured 10 times on the same scale as the Ruger triggers.
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.
