Original Springfield M-1863 Rifled Musket Converted to Miller Patent Breechloading Rifle

Regular price $1,995.00

Item Description

Original Item: One Only. This is really a Peach! This rifle started out as a Civil War Springfield Rifle Musket, dated 1863, made by PARKERS ' SNOW & CO. MERIDEN, CONN, as listed on the lock plate. There is also the "Spread Eagle" over U.S. marking, indicating military production. Around 700,000 were produced from 1863 until the end of the Civil War in 1865. With the advent of breech loading cartridge firearms, the government was looking for cost effective ways to modernize their rifles, and one way was to convert muzzle loading Rifle muskets to a breech loaders. 

The Miller Breach Loading system for the 1863 Springfield involves a flip up breach block allowing access to the chamber of the .58 Rimfire 39" barrel. The rifle now measures 56" in overall length.

The conversion breach block is stamped on the top:-

PATENT MAY 23.1865

In Military Trials in 1867 performance was spotty with several misfires however there appeared to be considerable gas "leakage" around the primer, resulting in this system not being adopted by the Government. Consequently few example were ever produced making these very rare. Our example is in very good condition, with crisp markings on the lock plate and breech block, though the metal finish is worn on the barrel and fittings. The stock is in good condition, though there are repairs around the lock, breech, and trigger guard, possibly from the weakening due to trials.

Bore is in excellent condition, with a bright finish and clear lands and grooves. The machine cutting marks can still be seen in the grooves. Fully cleaned and ready to display. Very Rare
