A semi-automatic sporting
rifle is created by the modification of a
fully automatic assault rifle Sa vz. 58. The semi-automatic
rifle is constructed partly from original parts of the Sa vz. 58
assault rifle, i.e. bolt carrier, locking piece, striker, return mechanism,
barrel, trigger,
interrupter and left hand side striker catch, partly from modified parts of Sa vz. 58
assault rifle, i.e. bolt, trigger mechanism
feather and safety catch and partly from newly manufactured parts, i.e. semi-automatic
receiver with a narrowed
magazine well for a single stack removable
magazine with extended bridge, safety catch with one more groove on its lower left hand side, new sporting stock where grip part and butt-stock part form one unit and
barrel extension permanently attached to the
muzzle. Some parts of the Sa vz. 58 assault
rifle are removed completely, i.e.
muzzle thread protector, bayonet lug, original
receiver, original stock, pistol grip, release, lever, trigger lever and right hand side striker catch. In a second version, an inseparable, double stack
magazine box is used.
