A practice attachment for firearms (1) provided with a bolt. The practice attachment comprises a practice bolt (3) and a practice barrel (2). The practice bolt (3) is exchangeable against the normal bolt of the firearm (1), and the practice barrel (2) can be inserted into the barrel (6) of the firearm (1). The handle (11) of the practice bolt (3) includes a gas discharging container, and at the firing of the firearm (1) a valve means (10) is actuated to release a gas batch, which via a passageway (35) is directed to a bullet (19) located in the bore (23) of the practice barrel (2), whereby the bullet (19) is forced out of the firearm (1). The practice attachment renders possible less expensive practice firing and practice firing indoors with firearms, which normally are intended for ammunition containing a powder charge. |
