The Interesting Parker Hale Rogun Shotgun

In the four years I have been blogging I don’t think I have come across a more obscure gun than the Parker Hale Rogun. I don’t know when the below prototype was made, if it was ever in production or even precisely how it functioned.

What I do know is that this pump action gun 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 (using, I would guess, a cylindrical cam/screw system so that the barrel is moved a shorter distance than the forend). 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. I can only imagine how dreadful this gun must have been to operate. Instead of moving the bolt mass around like in a conventional gun, the entire mass of the barrel had to be cammed back and forward.

The stock on this gun is also interesting. It is clearly a copy of the British L1A1 SLR stock. Parker Hale did in fact supply parts for the L1A1 so this stock could simply be a modified L1A1 SLR stock. Because it is using a synthetic L1A1-style stock, this gun probably had to be made somewhere between the late 1950s and early 1980s.

The patents for the successful Winchester Model 1897 and 1912 pump action shotguns would have expired long before this gun was conceived. I can’t imagine why they did not utilize the proven pump action concepts invented by Mr Browning so many decades earlier. Then again, it was not the strangest shotgun invented by the British post-WWII. At the risk of offending my British colleagues, I think at that time the British arms industry was desperate to regain the prominence they enjoyed in days long past and so had a touch of Not Invented Here syndrome.

    Well in fact the action is not that unique. The Russian-made RMB-93 shotgun has a similar style of operation, but is actually even more unorthodox because the tubular magazine is located above the barrel instead of under it.

    You can say I have a 12ga FAL!

  • anthony

    looks similar to the zlatoust rb-12

    Your “strangest shotgun” link is to a BSA 9mm submachinegun…

    Lame. One of the great things about pump action, the thing that makes it the fastest non-semi or double action gun is that the recoil of the gun actually helps pump the next round into the chamber. Reversing this cycle makes it more like a lever action (forward then back) and serves no purpose.

    this looks like it has been an L1A1 at some point, the grip seems similar to the l1A1s, the pump looks like a modified l1a1 handguard and like you said about the stock. This looks really interesting, but would it be practical for any type of shooting?

  • Raoul O’Shaughnessy

    So it’s a manually operated blow-forward design?

    As a gun hipster, let me just say that there are way more obscure guns out there that you’ve probably never heard of. The HK LMG11, Afansayev TKB-0136-3M, ARES FARC, and FN GPN, to name a few.

    “I can’t imagine why they did not utilize the proven pump action concepts invented by Mr Browning so many decades earlier.”

    John Moses Browning invented many things, but he did NOT invent the pump action shotgun. That honor goes to Christopher Miner Spencer, designer of the Spencer Rifle and Carbine adopted as the first repeating rifle used by the US Military during the War Between the States. More significantly, Spencer also invented the Automatic Screw Machine, which is a kind of fully automatic lathe that revolutionized industrial manufacturing in the late 19th century. Not until the advent of CNC technology in the 1960s was that improved upon.

    Is that a grip safety?

  • I wonder how you load the shotshells into the magazine.
