I decided to go with the Ruger BX drop in replacement trigger assembly after reading about it and watching the 5 minute video. One of my son's purchased mine from E. Arthur Brown Co. as a Father's Day present to me. I believe it topped out around $75 or $80 shipped to my door.
The trigger pull on the original Ruger 10/22 rifle bought many years ago was atrocious. I had trigger work in some fashion done on all my centerfire rifles including two lever action Marlin's. A gun smith solved that dilemma with installing Wild West Happy Triggers in the .35 Rem and the Mdl 1895 45-70. Again as memory serves, both guns were update for under $100 each approximately.
I also own a Savage Weather Warrior in .308 that came from the factory with the Accu-trigger and no need to do anything additional with that set up. I also have an older Ruger Mark II stainless in .270 Win that had trigger work done and has been a pleasure to shoot since then. The .270 turned in a two shot 1/4" group center to center at 100 yards approximately 1.5 inches high with Federal 150 grain Power Shoks. I have it sighted in for woods and farm fields encountered where I hunt in NY where 200 yards shots are RARE.
Back to the 10/22, after watching the 5 minute video twice, I did the installation myself including cleaning parts of the Ruger that had not seen daylight in a while in under 15 minutes.
I am totally impressed and pleased with the BX assembly, the video and written instructions and the incredible difference between the original factory 10/22 trigger and the drop in BX assembly. With the original gun which has sent numerous rounds downrange over the years, I was always fighting the trigger and although I got decent groups, I knew it could do better. I do not own a trigger gauge, however the BX is reputed to be around 2.5 lbs which is a big improvement over the factory trigger.
Here are some photos: From Left to right, the first one is a 5 shot group at 50 yards, measuring 1 7/16" including one flyer. . Center of group is 1.5" high.
The wind was moderate and mostly blowing left to right which probably accounts for some drifting at the 100 yard mark. I am sure if I spent more money on customizing, with a new crowned bull barrel, and other goodies, I could tighten these groups. Years ago I killed quite a few woodchucks out to 75 yards or so even with the old trigger. Out to 100 yards with the new BX trigger, I could make decent hits on anything I would want to shoot at with a .22 rimfire while holding dead on out to 75 and around 3 inches high at 100. I owned a Sako .222 back in 1968 after getting discharged from the U.S. Navy and that was predominantly my woodchuck gun for many years. I also took quite a few with the Ruger 10/22 and a Marlin bolt action .22 Mag.
