Military Grade: E1-E7 GENERAL EXPERIENCE: Experience or training which demonstrates a working knowledge to read and interpret instructions, repair manual, specifications, and drawings; must have a knowledge of shop mathematics sufficient to use testing devices and measuring instruments; and be proficient in the use and maintenance of hand tools and equipment.

SPECIALIZED EXPERIENCE: WG-08 - Experience or training which demonstrates ability to work effectively and efficiently on weapons and mechanical systems in disassembly for repair, inspection to diagnose mechanical malfunctioning, wear and/or damage is required. Experience in adjustment of levers, gear linkages and synchronization of interrelated mechanical systems.

Experience in applying technical manuals, regulations, specifications, and drawings to determine operation, assembly, and a tolerance of the variety of weapons cleaned, repaired, and modified, is required. Experience in using and maintaining a variety of hand and power tools and gages is required.

Tools include drills, files, saws, hammers, vises, and precision gages and measuring instruments such as micrometers, optical comparators, ultrasonic checkers, magnafluxing machines and/or borescopes to determine when parts are worn or damaged beyond acceptable tolerances. WG-09 - Experience or training with substantial mechanical skill is required to effectively and efficiently repair, overhaul, and rebuild small arms for both conventional uses and for weapons involving accurization.

Experience to inspect, diagnose malfunctioning, wear and/or damage is required. The ability to perform accurization procedures on weapons to improve their performance is required. Basic knowledge of other trades to modify and/or manufacture weapons parts for accurization is required. Experience to apply technical manuals, regulations, specifications and drawings to determine operation, assembly, and tolerances of the variety of weapons worked on is required for successful performance.

Experience using and maintaining a variety of hand and power tools and gages is required. Tools include drills, files, precision gages and measuring instruments, magnafluxing equipment and/or borescopes to determine when parts are worn or damaged beyond acceptable tolerances. Length of time is not of itself qualifying. Candidates' experience should be evaluated based on duties performed rather than strictly on the rank of the individual; however, established compatibility criteria/assignments must be followed.

The applicant's record of experience and/or training must show possession of the knowledge, skills and abilities needed to fully perform the duties of the position.

The purpose of this position is to perform maintenance, repair, and inspections on small arms and related devices. The primary purposes are to provide maintenance repair and accurization of national match weapons. This position is responsible for the following duties: 1. Performs accurization of national match weapons (pistols, rifles, and light machine guns) on a limited basis.

Accurization involves altering and refining mass-produced weapons for use in national competition, by increasing their accuracy and reliability beyond factory specifications. This process involves selecting, fitting, and altering parts to improve the weapon.

Altering includes peening, bending, filing, grinding, and the use of lapping compound to alter parts such as individual slide, receiver, sear, disconnector, barrel, barrel bushing, magazine, hammer, recoil spring, flash suppressor, operating rod spring guide, gas cylinder, stock, and the spindle valve. 2. Disassembles weapons, assemblies, subassemblies and other components. Examines for defects, misalignment and malfunctions.

Replaces barrels, firing pins, springs, trigger mechanisms, shell ejectors, and other parts and assemblies. Modifies small weapons by replacing worn or obsolete parts and using hand and power tools, precision gauges, test instruments, jigs and alignment devices in making repairs, modifications, and adjustments. Applies final finishes and test fires and/or performs operational checks of arms repaired to ensure safety, accuracy, and ease of operation. 3.

Performs overhaul, maintenance, and repair on a variety of small arms. Diagnoses and identifies mechanical deficiencies and/or malfunctions in weapons including: automatic pistols, revolvers, shotguns, automatic rifles, grenade launchers, machine guns, and rocket launchers, and other small arms and accessories. 4. Uses micrometer to measure altered tolerances and makes additional adjustments as required. Anneals certain parts until the proper temper of the metal is obtained.

Selects certain parts of specific hardness by researching characteristics of various metals in technical manuals. Uses pre-set specifications to ensure that critical operating tolerances are met. Test fires weapons to ensure that they meet desired performance requirements. Performs other duties as assigned.
