Abstract: A mounting system securing a firearm sight to a firearm accessory rail includes a clamp with a downwardly open rail cavity for slidably engaging the rail. The sight is matched to a plate with pins that correspond to the sockets on the bottom of the sight, and the plate has sockets that correspond to pins on a base that contacts the rail. The clamp extends through the base and plate allowing the sight to be secured to the clamp. Securing the sigh to the clamp compresses the base, plate, and sight toward the rail, placing the system in tension to hold the sight to the firearm.

Abstract: A firearm sight including a base coupled to a firearm receiver. The base includes a body having opposed side defining a void therebetween. A sight housing having an end coupled to the base and an opposing end carrying a sight structure. The end coupled to the base is bifurcated with spaced apart furcated portions defining a central gap therebetween. A threaded support member extends transversely between the opposed side portions and concurrently through apertures formed through the furcated portions. A wheel member has a threaded bore and is received on the threaded support member between the furcated portions within the central gap. Rotation of the wheel member moves the sight housing laterally between the opposed sides of the base.

Abstract: A magazine release device is affixed to a firearm and operable from either side of the firearm. The device includes a shaft extending between opposite sides of the lower receiver and movable longitudinally between an engaged and a disengaged orientation. A spring biases the shaft into the engaged orientation. A plate, affixed to one end of the shaft, includes an inwardly directed catch that engages with a magazine when the shaft is in the engaged orientation and disengages from the magazine when the shaft is moved to the disengaged orientation. A right hand actuation button is affixed to the shaft on the right side of the lower receiver and a left hand actuation button is affixed to the plate on the left side and each actuation button controls the shaft and plate between the disengaged orientation and the engaged orientation.

Abstract: A foregrip for use with a firearm having a handguard extending along the barrel and a mounting rail, with transverse spaced apart slots, extending longitudinally along a lower surface of the handguard parallel with the barrel and including slots spaced there along.
