Abstract

The present invention relates to a bendable firearm having an off-axis shoulder rest and a sight, which enables stable aiming and firing since a shoulder rest is bent in an off-axis shape and provides a new structure having excellent stability by minimizing exposure of the body.

2. The bendable firearm according to claim 1, wherein:

the first adaptor (420) is rotatably coupled to a rear end of a first auxiliary adaptor (410) screwed into the firearm body (100) so as to be connected to the firearm body (100) by the first auxiliary adaptor (410);

an angle adjusting means for adjusting an rotational angle of the first adaptor (420) is provided between the first adaptor (420) and the first auxiliary adaptor (410).

3. The bendable firearm according to claim 2, wherein:

a plurality of pin holes (421) are formed in the connecting bar (422) in a longitudinal direction;

an insertion recess (442) into which the connecting bar (422) is inserted in a width direction and a pair of upper and lower pin holes (443) configured to cross the insertion recess (442) are formed at the front end of the second adaptor (440); and

the second adaptor (440) and the connecting bar (422) are detachably coupled by fixing pins (449) inserted into the aligned pin holes (421, 443) of the connecting bar (422) and the second adaptor (440).

4. The bendable firearm according to claim 2, wherein:

a plurality of pin holes (421) are formed in the connecting bar (422) in a longitudinal direction;

an insertion recess (442) into which the connecting bar (422) is inserted in a width direction, a pair of upper and lower pin holes (443) configured to cross the insertion recess (442), and a pair of auxiliary holes (443-1) located back of the pin holes (443) so as to be parallel with the pin holes (443) are formed at the front end of the second adaptor (440);

push bars (448), which are made up of push portions (448-2) that are connected to one ends of the key portions (448-1) and are inserted into the auxiliary holes (443-1) such that front ends thereof are exposed to outside of the auxiliary holes (443-1), are elastically installed on the second adaptor (440) by springs (470); and

the key portions (448-1) are inserted into the aligned pin holes (421, 443) of the connecting bar (422) and the second adaptor (440), and the second adaptor (440) and the connecting bar (422) are detachably coupled by fixing pins (449).

5. The bendable firearm according to claim 1, wherein the sight (300) includes:

a base (310) that is detachably coupled to the firearm body (100);

a main body tube (320) that is coupled to the base (310);

a T-shaped connector (330) that is formed with a branch tube (331), has a T shape, and is coupled to the main body tube (320); and
