Abstract
An integrated leveler assembly in combination with a rail portion for an upper receiver and a handguard, where the upper receiver and handguard are core components of a modular rifle assembly. The integrated leveler assembly is configured to fit within a slot formed between the two aligned end-to-end rail portions such that the integrated leveling assembly may not extend above the combined rail portions and the rail portions form a single aligned rail platform. The integrated leveler assembly includes a liquid-filled level vial that forms a bubble, a level vial barrel receiver, and fasteners to secure the integrated leveler assembly to the two rail portions of the rail platform. The integrated leveler assembly may include an extension spring, guide slot, lock pin, and cam lock, along with a separate barrel that axially receives the level vial receiver with an extension spring between the level vial receiver and the barrel.
