Stabilizing Recoil Lug and Rail for Rifle Scope Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scope mounts on rifles are insufficiently anchored, leading to scope instability and misalignment due to inadequate attachment to the action receiver, particularly during recoil and vibrations, which can be critical in precision long-range shooting and emergency situations.
Innovation Solution
A stabilizing recoil lug with a key that fits into a pocket on the scope base, ensuring the scope and barrel move together during recoil and vibrations, providing additional reinforcement against shear forces and maintaining alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If rails are attached to the action receiver by only a few small screws, then the device complexity is reduced, but the reliability of scope mounting deteriorates
Solution Approach 1:
The patent introduces a stabilizing recoil lug as an intermediary component between the barrel and the action receiver. This lug includes a key that fits into a pocket on the scope base, creating a mechanical linkage that ensures the scope and barrel move together during recoil. The intermediary lug with its key-pocket interface resolves the contradiction by providing reliable scope mounting stability without requiring complex attachment structures, as it leverages the existing recoil lug already present in the rifle assembly.
2Ease of manufacture
If existing keyed lugs are used to guide the barrel, then the ease of manufacture is improved, but the stability of the rail against shear forces deteriorates
Solution Approach 1:
The patent applies local quality by modifying only the critical interface between the scope base and the recoil lug. Specifically, a pocket is cut into the bottom of the scope base at the precise location where it contacts the recoil lug, and a corresponding key is formed on the top of the recoil lug. This localized modification provides enhanced stability against shear forces during recoil while maintaining the overall simplicity and ease of manufacture of the components. The key-pocket interface concentrates the stabilizing function at the exact point where it is needed, without requiring changes to the entire rail or lug structure.

AI summary
A device and method for stabilizing a rifle scope that employs a pocket cut in the bottom of a scope base (picatinny rail) that precisely mates with a key formed on the top of a recoil lug, such that when the scope base is attached to the rifle's action receiver and mated with the lug's key, the lug holds the barrel and the scope base locked in tandem so that they move exactly together during recoil events or any vibrations experienced by the rifle.
