A magazine well for receiving a portion of a firearm magazine. The magazine well includes a cavity for receiving the portion of the magazine, the cavity having an input end and a second end opposite the input end. The cavity further includes a channel extending from the input end to the second end, wherein the channel has a tapered portion with a larger cross-sectional diameter closest to the input end of the cavity.

A weapon sight interface for mounting a device on a weapon having a rear sight and front sight, including an enhanced rear sight for replacing the rear sight of the weapon, having a base for installing in a dovetail slot of the weapon, an elongated tail that extends along the barrel of the weapon; and one or more tritium dots or white dots configured to enable use of the enhanced rear sight as a rear sight of the weapon; and also having a quick release interface for attaching to the device and locking onto the enhanced rear sight, having guides to securely fit onto the enhanced rear sight, a quick release lever, which in a first position causes the guides to lock onto the enhanced rear sight and in a second position releases the enhanced rear sight so that the quick release interface can slide off.

An electronic indicator on a see-through optical scope indicates whether an optical system is canted. The indicator may include illuminable visual indicators positioned on opposite sides of a field of view through the optical scope. The indicator may be visual, haptic, or aural. The visual indicator may include one or more LEDs positioned on the periphery of the field of view, and may be optically coupled to an appropriate position on the face of the reticle using a suitable waveguide. The LEDs are coupled to a microprocessor which is, in turn, coupled to a solid-state electronic inclinometer that is incorporated into the internal structure of the optical system. The microprocessor is configured to selectively illuminate one or more of the visual indicators based on the output of the inclinometer, thereby indicating how the reticle is canted, if at all.

A system and method for a weapon accessory mount is disclosed. The weapon accessory mount is configured to attach a weapon accessory to a rail of a weapon configured to fire a projectile in a projectile path. A flexure is configured to receive the weapon accessory. The flexure includes a first end attached to the rail at a first pivot portion, and a second end opposite the first end attached to the rail at a second portion. The first pivot portion is configured to convert at least a portion of energy of a shock recoil from the weapon from translational energy to rotational energy, the second pivot portion has a similar functionality to the first pivot portion.

A measurement system according the current application facilitates the positioning of scope relative to a rifle or other firearm and the subsequent measurements needed to procure a ring or set of rings with which to mount the scope to the rifle. A base is attached to a rail of the rifle and the scope is placed in a holding ring. Spacers are placed between the base and the holding ring to locate the scope. The base, spacers and holding ring are removably attached to each other.
