Firearm

Abstract

A firearm comprising a barrel assembly mounted at one end to a butt group, the butt group including a firing mechanism and an ammunition entry point; a gun lock group slidably mounted between the barrel assembly and butt group that slides to load ammunition from the ammunition entry port into a barrel of the barrel assembly upon cocking of the firearm; and a rail for accessory attachment that is mounted on the barrel and in direct contact with a portion of the barrel. The second invention relates to a hammer pack in the butt group that automatically resets the firing mechanism upon recoiling of the gun lock group during firing, wherein the hammer pack includes a hammer biased to pivot under the force of a hammer spring, and an autofire lever biased through an autofire lever spring to engage the hammer.

Description

[0001]The present invention relates to a firearm, and more specifically to a rifle.BACKGROUND[0002]The development of firearms has rapidly progressed with advancements in materials, in munitions technologies and in response to requirements for greater weapon versatility and for improved performance. Firearms can be single shot firearms or ‘repeating’ firearms where multiple cartridges are loaded. In semi-automatic firearms the next cartridge round is automatically re-cocked and re-loaded and in fully automatic firearms the firing mechanisms enable rapid fire by automatically re-cocking, re-loading and firing so long as the firing trigger is depressed. Some firearms have a selective firing option that allows a user to switch between semi-automatic and fully automatic firing modes.[0003]Referring specifically to rifles, these firearms use magazines of munitions loaded into the receiver of the rifle. The rifle's bolt and carrier feeds ammunition into the rifle's breech in is preparatio...

AI Technical Summary

Benefits of technology

The invention relates to a firearm, particularly to the upper and lower rails and barrel. The fluted barrel helps reduce weight and provides a direct and continuous contact between the upper and lower rails, as well as alignment. The lower rail can be used to attach a grenade launcher and the trigger extends into the hand guard for easy switching between rifle and grenade launching. The barrel is exposed to airflow to promote cooling and may be fluted to reduce material used and weight.

Problems solved by technology

Owing to the configuration of the firearm and the availability of rail space on the attachment rail, the number of accessory attachments that are mountable on a rifle at the same time is limited.

Furthermore, the attachment and detachment of accessories should cause minimal interference with the accessory's alignment with the rifle barrel as interference could otherwise lead to inconsistent and imprecise firing accuracy.

An important issue overarching the above mentioned desirable features in a firearm, and in particular a rifle, is the pursuit of weight reduction.

With common assault rifles weighing approximately 3-4 kilograms (without ancillary attachments) the weight of a rifle on military personnel required to carry the firearm for long periods can be taxing and will contribute to fatigue.
