Novel Improvements for KRISS-type Firearm and Magazines for these Firearms

Abstract

The invention relates to improvements in the design and operating mechanisms in a KRISS-type firearm, or a firearm employing a mobile mass. In one aspect, the invention is an improved cocking lever assembly comprising a main pin provided with a tenon (9) at one end (E), with a supporting compression spring (5), a cocking button (3), and a retention means (4), attached to a mobile mass (1). This assembly allows direct activation of the mobile mass (1) by the action of the operator's force on the cocking lever. Advantageously, this cocking lever assembly can be mounted indiscriminately on the right or the left of the mobile mass (1) and therefore of the firearm, according to the user's preference. This cocking lever assembly combines certain safety criteria with the option of ambidextrous use often preferred in modern firearms.

AI Technical Summary

Benefits of technology

[0006]The invention involves two improvements to the use and operation of the KRISS-type firearm, described in several published documents including U.S. Pat. Nos. 7,997,183 and 7,201,094, both of which are specifically incorporated herein by reference. This type of firearm can employ a mobile mass, which can also be called a slider or inertia block, to control recoil forces and which moves in concert with the bolt of the firearm during the firing cycle. In one aspect,

Problems solved by technology

In some firearms, extended magazines have the problem of vibrating and falling out of the magazine well while firing.
