Taking a look at one of the best sniper rifles of the Great War (VIDEO)

Ian McCollum with Forgotten Weapons looks at the Winchester Pattern 14 sniper rifle made for the British Army in WWI.

The rifle, technically a P14 MK I*W(T) with a semi-adjustable 3x BSA Model 1918 telescopic sight, was an American-made sniper model chambered in .303. Used late in the war and, as McCollum notes, it was one of the most mature designs of the conflict.

These guns proved accurate and reliable enough that they went on to a long life, being used by British and Commonwealth forces in WWII and others.

Among the “others” was a stockpile of 75 guns sent to the Irish Free State by Britain in the 1930s and, after service in that country, were sold as surplus in the U.S. in the 1950s. One of these Irish P14s, seen in the above video with McCollum, is up for auction this month with Rock Island.
