Despite these detriments, the rifle performed much better than expected, and the Master-General of Ordnance ordered it to be produced with a 30-inch (76 cm) barrel of .654 inches (16.6 mm) caliber.

In January the following year, it became apparent that 600 of these would be required urgently for Col. Brown's Battalion of the Rifle Brigade and the Enfield factory would not be able to supply them in time.

The Brunswick rifle developed a reputation for being difficult to load, but was fairly well received and remained in production for almost 50 years.

Limited numbers of Brunswick rifles were imported to the United States during the Civil War.

Some of those ended up in the hands of units such as the 26th Louisiana Infantry, which was partly equipped with Brunswicks during the Siege of Vicksburg.

Since the Brunswick used a round that was specifically designed to be mated with the grooves in the rifle, it had to be oriented properly in order to be loaded.

The stock was made of walnut, and featured a straight wrist and a low comb butt.

The ramrod pipes, trigger guard, and butt plate were all made of polished brass.

The bayonet bar was relocated further back due to problems that had been experienced with the Baker rifle.

[5] The rifle weighed approximately 9 to 10 lb (4.1 to 4.5 kg) (depending on the pattern) without the bayonet attached.

The Pattern 1836 featured the original back action lock and the single compartment patch box.
