The SREM-1 (Sniper Rifle, Experimental Model 1), also known as simply the Enfield Sniper Rifle is an early bullpup weapon. It is an experimental British bullpup sniper rifle from 1944, near the end of World War II. It is a manually-operated bullpup sniper rifle whose action cycled through a movable pistol grip.
A catch is stamped into the left side of the stock above the pistol grip. To operate the weapon, the pistol grip is pulled backwards into the stock, ejecting the spent casing. The grip then is pushed forward, loading a new round into the chamber.
A few different models of the weapon exist. The weapon was eventually abandoned and did not progress beyond the prototype stage.
