A mount for a firearm has a body having a first clamp configured to engage a first edge of the rail, a jaw movably connected to the body and having a second clamp opposed to the first clamp and operable with the respective clamps to engage respective opposed lateral edges of the rail, a spring biasing the jaw toward the body, and at least a portion of the spring being between the clamps. There may be a pushrod connected to a first one of the body and the jaw and slidably received by the other of the body and the jaw. The spring may be laterally positioned to one side of the pushrod. The spring may be a coil spring having a spring axis offset from a pushrod axis defined by the pushrod.

Rifles having a weapon median plane, with a barrel with a barrel bore axis, a gas drive, a sliding block, a closing spring unit, and a charging handle assembly arranged in front of the sliding block, where the charging handle has two operating handles pivotally mounted about pivot pins on a slider body, said operating handles being pushed about the pivot pins into their rest position by at least one handle spring. For facilitating the use and especially the forward shift of the charging handle, the slider body is mounted on a carriage which is arranged axially in front of the sliding block and movable in the axial direction.

A gas block for a firearm may include a quick release sling attachment. The sling attachment utilizes a pin that engages with a bore in the body of the gas block. The sling attachment features a ring that can be in a fixed position or can swivel.

A firearm magazine case that is sized to hold a stack of firearm magazines, which case includes a spring mechanism at one end such that the magazines are advanced within the case to a ready position as the magazines are extracted from the case and configured to be mounted on a person's front or side so that the magazines are reached with an easy and natural motion, whereby the case is contoured to a person's body and is configured such that magazines are able to be extracted in one step, yet are effectively protected from the environment, the case includes an attachment mechanism that allows the case to be mounted either horizontally or vertically, according to the user's preference, the case's attachment mechanism, which consists of an “x” shaped ridge or lip which coordinates to accept a triangular insert that is attached to a person's clothing, whereby sliding any side of the “x” down over the triangle attaches the case in a secure manner, yet allows the case to be quickly and easily detached and/or replaced with a new magazine dispenser, and the case is stackable (and perhaps joiningly stackable) with other cases.

A rifle includes a magazine well, a barrel, and an exo-bolt. The barrel is configured to be detachably coupled to the magazine well. The barrel includes a forward barrel portion on an end of the barrel opposite the magazine well. The exo-bolt is configured to travel along an exterior of the barrel.

Magazine holders for firearms, including two actuating elements and a spring, where the first actuating element-has a locking extension for the temporary attachment of a magazine and a first actuating extension, the second actuating element has a second actuating extension, and where the two actuating elements are (operatively) connected to one another such that the locking extension releases the fastening of the magazine counter to the tension of the spring during a release movement onto one of the two actuating elements. Each actuating element is designed as one piece, in that the second actuating element has a bearing extension on an end section facing away form the second actuating extension and connected by a connecting section, and the first actuating element has a substantially shape-complementary bearing opening for receiving the bearing extension in an assembling position.

Disclosed herein is a magazine release. The magazine release includes a spring retainer slot and a spring channel. The spring retainer slot is spaced between a first end and a second end of the magazine release. The spring channel is at a bottom side of the magazine release. The spring channel is adjacent the spring retainer slot. The spring channel is spaced from a top side of the magazine release. The spring channel extends between a front side and a back side of the magazine release. The spring retainer slot includes a first depth from the bottom side. The spring channel includes a second depth from the bottom side. The first depth is substantially equal to the second depth.
