The 303 was the first rifle on the market to incorporate a manual cocking insurance system.
Safe and quiet for greater comfort avoiding undue noise. It sure prevents the operation if the weapon is not fully armed.
The gas intake system is not welded or bolted to the barrel.
The support is made in such a way that it allows the barrel to float and adequate rifle precision, impossible if the gas system is fixed to the barrel.
Removable 2 or 5 cartridge magazine.
Flip-up mount that mounts quickly and accurately to the base of the rifle with the lowest possible height for a more comfortable face.
Aluminum casing, which separates the cylinder head and front into two parts, which in turn allows it to go from wood to fiber and vice versa in a matter of seconds.
