An extended rigid interface frame with upper and lower rails joined to a firearm receiver and extending forward above the firearm's barrel to a head assembly replacing the firearm's normal front sight. A weaver type interface return portion is provided below the barrel from the head assembly to the receiver. A yoke braces the extended rigid frame receiver sleeve of the present invention to the forward portion of the firearm's receiver. The distal end of the extended rigid frame receiver sleeve terminates in the front sight housing which connects the upper and lower rails and provides a housing for advanced laser and sensor components, and the standard front sight bead. The front sight housing is self supported by the connection of the upper and lower rails running back to the yoke and secured to the top of the receiver. The barrel of the rifle is free floating in that it does not touch the extended rigid frame receiver sleeve in any manner. Protective spring-loaded hand guards are incorporated into the extended rigid frame receiver sleeve, thereby protecting a user's hands from a hot barrel, eliminating any pressure on the barrel, and providing quick access to the barrel area.
An extended rigid frame receiver sleeve for interfacing integrated and modular enhancements to a firearm having forward and rearward portions, said firearm having minimally a receiver with a stock and barrel attached thereto, said barrel defining the forward portion of the firearm and said stock defining the rearward portion of the firearm, said firearm longitudinal axis being defined as horizontal and running from said stock through said receiver to said barrel, said receiver being comprised of an upper receiver and a lower receiver, said upper receiver having a forward portion, a top and a rearward portion, said barrel being joined to the forward portion of the upper receiver, comprising:
