Our Hawken Squirrel Rifle breech plug is a popular early design called a “solid patent breech”. This sturdy one piece percussion plug, with integral bolster, was popular on percussion fullstock and halfstock Plains rifles, Ohio rifles and late longrifles, from the 1830 to 1880 era. The beavertail tang reinforces the wrist on Saint Louis style rifles, or may be shortened for Eastern style rifles.

This plug fits a 15/16” octagon barrel with 5/8-18 thread, and features a direct drilled ignition channel. Order our standard #RST-S 1/4-28 nipple for use on a rifle, or our shorter #PST-A nipple for use on a pistol. Consider ordering our small pistol size #Lock-HP or larger rifle size #Lock-JB-R for use with this breech plug. The breech plug bolster adds about one inch to the overall barrel assembly length.
