Parker Hale Rogun


 * Not to be confused with the Submachine gun of Rhodesian origin

The Parker Hale Rogun is a shotgun of British origin.

Overview
The Rogun has a unique action. Its bold head is fixed to the back of the receiver. When it is pumped forward (it is operated by a forward then back motion, the opposite of most conventional pump actions today) the barrel is pushed forward. While the barrel is moving forward, a feeding device is rotated and scoops up a cartridge from the magazine. When the forend is pumped back, the barrel is moved back toward the bolt head, scooping up and chambering the cartridge. Instead of moving the bolt mass around like in a conventional gun, the whole barrel had to be cammed back and forward.

The stock on the Rogun is of the British L1A1 Self-Loading Rifle. Parker Hale did in fact supply parts for the L1A1. Because it is using a synthetic L1A1-style stock, this gun probably had to be made somewhere between the late 1950s and early 1980s.
