L&R's of late have improved, and while their QC is not yet quite at the level of Chambers, they have really improved int the last couple of years. The frizzens seem to be of a proper hardness of late and spark well, and the springs seem to be stronger, and so they tend to work well compared to years past. Good flints also help in proper operation, which means black english, and Rich Pierce of the proper size. Let me restate that. FLINTS OF THE PROPER SIZE make a big difference. That cut agate stuff is @#$%/!!, don't waste your money.We need every pattern of lock we can get for correct style of builds, so if we keep letting L&R and others know of the problems they should improve their quality. The reason I'm concerned about losing lock companies, is that it will create weird guns, such as right now on the Track site there are about six or seven Southern rifles with German Chambers locks, and only one that bothered to do enough research to put a proper English lock on their build. Thats' really sad. There are many quality locks out there to chose from, so don't despair. Spend your time to make sure you have a good lock, as it is the heart of the gun you build, and if it doesn't work , you then have a stick.
