The inside mounted frizzen screw on a Investarms produced Lyman Great Plains Rifle flintlock requires a longer frizzen screw with a nut to mount a flash guard. This same lock and screw is used on the Lyman Trade Rifle and Deerstalker, Investarms: Hawken, Bridger Hawken, Gemmer Hawken, and older Cabela's Hawken. Installation of a iron or brass flash guard, protects the shooter next to you from overspray vented from your flash hole. This protection is required at most-re-enactments, where flint shooters may stand and fire volleys shoulder-to-shoulder.

Due to the small size of this lock the flash guard will require a small amount of shaping to allow clearance for the frizzen travel. To install this screw. Dismount the lock from the gun. Use a mainspring vise to gently compress the frizzen spring only enough to remove tension on the frizzen. Remove the frizzen screw using a well fitted screw driver. Install the flashguard screw through the plate and frizzen. Place your flash guard over the threaded end of the screw. Install the nut. The nut is designed to be a tight fit on the male threads, it will be snug as it goes on. Use a wrench, a percussion nipple wrench also works well to drive the nut. The nut has a small shoulder that will center the mounting screw hole on the flash guard. Tighten it down snug. These require cutting a small amount of material from the inside corner to allow the frizzen clearance as it travels.

We offer a number of different flash guards. Available unmarked, with a French "Fleur-de-Lis" cartouche , or the English "Crown" mark over the letters "GR" for "Georgus Rex" (George the King).
