I recently added a Rock River National Match upper to my Bushy lower. I shot the rifle for the first time today. Extraction was faultless. Two major problems. 1. Upon firing, bolt cycles automatically, but the trigger is not reset. The trigger resets when I partially cycle the bolt by hand. What might be going on? The hammer might be cocking as designed, but the force of the bolt returning releases the hammer. No slam fire experienced. If this is possible, would setting the pull a bit higher resolve this issue? Is this even a possibility? 2. A few light strikes and no kaboom. The Jewell comes with a lighter hammer. Any help would be appreciated. |

Your Jewell is outta adjustment, wish I had my instructions handy (I could be of better help to ya, sorry), but suggest you review them. Believe you have trigger set too lite, also don't forget to break it in properly after ya get it set right, IIRC ya need to dry fire the trigger considerably once set and installed. BTT, for others w/ comments, it's been too long since I installed one and I've just plain forgotten all the specifics of Jewell installations. Will say this, once it's installed/set correctly I haven't messed with it, except to occasionally dig a primer out of it w/ a dental pick, and oil lightly. Mike |

Give me a call, I bet I know what is wrong. Or check to be sure that the "Long Leg" is in the Sprocket and not under the rivet on the trigger. 9. Move long leg of trigger spring into the second or third notch in the adjustment plate. A special tool has been provided to do this. This tool is the thin piece of piano wire bent to an “L” shape with a small hook on the long end. Grasp this tool by the “L” and use the small hook to grab the long leg of the trigger spring and reposition it as needed. This can also be done with needle nose pliers or forceps, but the “L” tool makes is much easier, particularly when the upper receiver is in place and the rifle is in the field. Make sure the trigger spring is on the trigger assembly and returns the trigger when the trigger is pulled. When the spring leg gets to the vertical position it easier to push it aft with the other tool, the fork tool. Hope this helps, Tommy GPSS |

Tommy: Long leg seems to be behaving itself. I increased the overtravel by 1/4 turn and this seems to have solved my trigger reset problem, but the trigger is not fully resetting and that is the basis of my light strikes. It looks like the trigger is resetting to about a 30 degrees from vertical and is not resetting to the proper position, which is about 70 degrees from vertical. I've relubricated the trigger to reduce friction on the reset. I won't be able to shoot for a weeks, or so. |
| You may have the second stage set too light, resulting in the sear not catching and allowing the hammer to ride down to the "half-cock" notch. The trigger is only reliable with at least 1 lb on the second stage. Too little sear engagement can cause the same problem. See Mike Crisler's instructions for setting up the Jewell at http://www.highpowerrifle.com/ |
| I just installed a new Jewell. Haven't checked it yet on the range but sure feels good! But am also struggling with the description of the spring "long leg". Mike seems to say put the "L' shaped end under the rivet. Tommy seems to say it belongs in the adjustment wheel. Mike tried to send me a file to explain but it wouldn't come thru. I will call Tommy on Monday and post a reply. |

The one with the "Long Leg" goes in the Sprocket. It is longer to keep it from being accidently released while putting tension on it and preventing it from falling under the hammer. Do it the other way, results in light strikes and a PITA if it falls under the hammer. Tommy GPSS |
