GAS SYSTEM

The only normal maintenance procedure requiring any

disassembly pertains to gas system care [see figure 6]. After

clearing the action, making sure the rifle is unloaded and safe,

remove gas cylinder plug (29) using a Springfield Armory

combination tool or a socket wrench by turning it counter-

clockwise and withdrawing it from the gas cylinder (23). Tilting

the rifle muzzle down, remove the gas piston (27), clean with

bore solvent and wipe dry. Clean the inside of the gas cylinder

and wipe dry. Use a #15 aircraft length drill bit and a letter “P”

standard drill bit to remove carbon from inside the piston and

plug. Use 3M Scotch Brite (green scuff pad) to remove build-

up on the outside of the piston. Insert the piston into the gas

cylinder with the flat side up toward barrel. Make sure the

piston is completely below the threads in the gas cylinder

before replacing plug.

Re-assemble dry - apply a SMALL dab

of grease to the threads on the plug. CAUTION: The gas piston was designed to operate dry.

CLEANING

The bore and chamber should be regularly cleaned using proper equipment. Modern barrels shoot better when

clean. To properly clean the barrel you should remove powder fouling and gilding metal from the bore, clean the

flash suppressor and clean various residue from the chamber. When cleaning the barrel, place the rifle upside

down to prevent solvent, oil, etc. from entering the stock and the gas system.
