Early Semi-Auto Conversions – The Howell M1915 Enfield Conversion with Forgotten Weapons

As weapons technology has progressed through generational leaps, it has bee historically common for notoriously frugal militaries to look to adapting their current standard issue to the new development. Generally speaking, these attempts are disasters as the technological leap is difficult to adapt to the old weapon system. Often, these systems are kludgy, if they work.

Notable exceptions to this rule do exist, but it should be known they are truly exceptions. This includes the Pederson device among few others. More often, but still rare are the conversions that indeed work, but are obviously major changes to base platform and are not accepted for one reason or another. A fine example of this is the Howell M1915 conversion for the standard British issue SMLE rifle.

In short, the Howell conversion adds an external long-stroke piston system to the side of the SMLE. Its a notable example for not significantly changing the base action, rather adding the minimal modifications necessary for the weapon to be functional… and usable. The result is a combination medieval and steampunk interpretation of a semi-auto rifle – which I love looking at.

Where the bolt-action rifle would potentially hit the shooter in the face if they did not move their cheek during cycling, the Howell adds a facial shield and offsets the sights to the left-hand side of the weapon. The weapon is decidedly not southpaw friendly, but in its defense, the SMLE was not either.

    Even though its expensive, bulky and prone to hurting the operator if they don’t know how to use it. I still think it looks badass.

  • In a cooler world than this one, these were standard issue for airship crews to repel rappeling zeppelin raiders.

      When I fought in the Great Zeppelin War, all the solders in my unit had cut these guns down as short as they could go without modifying the action.Then our airship would fly over one of the Huns zeppelins, and then my unit would repel down on too the zeppelin while firing one handed on the way down.
