A used L&R back action lock by L&R Lock Company. The lock plate has been reshaped and tapped for a 10-32 threaded lock bolt. Called “back action” because the mainspring hangs behind the tumbler, this lock was popular on percussion guns made in St. Louis, New York, California, Ohio, England and Belgium. Swivel breech double rifles require a back action lock mechanism. Makers of target rifles, slug guns and Sniper’s rifles of the 1840 to 1880 preferred these long thin locks.
These nice locks feature a fly detent, for use with set triggers. The mainspring and stirrup result in fast lock time, making this lock a good choice for the serious target shooter. The hammer has a 1.625” throw for use with barrels from 13/16” up to 1-1/4”. Notched at the tail to hook under a wood screw, we recommend that you use our #6 x 1/2” screw, set permanently in the lock mortise.
