Rear Sight Block for AK-Type Rifles

US9696118

Implementations of a rear sight block for AK-type rifles are provided. In some implementations, the rear sight block may be drop-in-compatible with most AK-type rifles and performs several functions (e.g., providing a guide hole for the piston of an AK-type rifles operating system) associated with prior art rear sight blocks found on AK-type rifles. In some implementations, the rear sight block disclosed herein comprises an optic mounting interface having an integral rear sight notch therein, and at least one accessory mounting interface. In some implementations, the optic mounting interface places an optical gun sight secured thereto in line with the iron sights of the host AK-type rifle. In some implementations, the accessory mounting interface may be used to position a flashlight, laser, and/or other firearm accessory on the left (or right) side of the rear sight block.

 

MERC Free-Float Hand Guard

US10480897B2

Implementations of a handguard system for firearms is provided. The handguard system is configured for use with a rifle (e.g., an AK-type rifle) and to support rail mounted firearm accessories. In some implementations, the handguard system comprises a rear sight block configured to fit about the barrel of a rifle and a handguard that can be removably secured to the rear sight block without making contact with the barrel (i.e. the handguard system is free-floating). In other implementations, the handguard system comprises a rear sight block and a handguard that can be removably secured together and thereby form a clamp that secures the handguard system to the barrel of a rifle. The handguard may be configured so that modular sections of MIL-STD-1913 mounting rail can be attached to various locations on the handguard as needed to provide a mounting structure for MIL-STD-1913 rail mounted firearm accessories.

US20190162504A1

Implementations of a handguard system for firearms is provided. The handguard system is configured for use with a rifle (e.g., an AK-type rifle) and to support rail mounted firearm accessories. In some implementations, the handguard system comprises a two-part barrel clamp configured to be secured on a rifle barrel, a gas tube configured to be secured to the top portion of the two-part barrel clamp, and a handguard configured to be removably secured to the two-part barrel clamp. The two-part barrel clamp comprises a top portion and a bottom portion that can be secured together and thereby cooperatively engage with the outer surface of a firearm barrel. The handguard may be configured so that modular sections of MIL-STD-1913 mounting rail can be attached to various locations on the handguard as needed to provide a mounting structure for MIL-STD-1913 rail mounted firearm accessories.

Occam Lube

US10493484B2

Implementations of an applicator syringe are provided. In some implementations, the applicator syringe may be configured to dispense a lubricant from a dispensing needle thereof. In some implementations, the applicator syringe may be configured so that the plunger shaft and the dispensing needle are removable when not in use. In some implementations, when the applicator syringe has been disassembled, the dispensing needle may be stored within the barrel of the applicator syringe and the plunger shaft secured about the exterior of the barrel. In some implementations, the applicator syringe may comprise a barrel having a finger flange, a plunger positioned within the interior chamber of the barrel, a plunger shaft configured to urge the plunger forward, a dispensing needle that can be removably secured to the front end of the barrel, a removable cap, and a barrel plug.
