he Lockinq Lugs are the most important area to clean on the weapon. Loose powderesidue builds up in the recess in front of the lugs. This buildup may bind the bolt andrevent it from cycling smoothly. The loose residue in this area will eventually pack ifot removed. One cause of buildup in the locking lugs is incorrect cleaning. If you pullr push a brush back toward the chamber dirt from the bore and chamber can beeposited in the recess.

he Chamber must be keep clean to allow easy extraction of the empty shell. Ifcratches are present the case fire forms into these recesses and prevents the caserom ejecting. It is normal to get a gummy residue buildup at the chamber shoulder.his is loosened with the chamber brush. The rotating swab will mop the loose residueut. Pay special attention to this area after firing blank rounds.

he Neck and shoulder of the neck are cleaned by rotating the bore brush and swabefore the bore is cleaned. Keep this area clean.

he Bore should only be cleaned in the direction of the bullet. If you take abrasive dirtrom the muzzle and introduce it into the chamber and neck, the bullet will drag it downhe bore. This dirt can cause bore and throat erosion. The crown of the muzzle givesbullet its final direction. Take care not to nick or scratch this area.

CHECK TO MAKE SURETHE WEAPON IS UNLOADED

ANDTHE MAGAZINE IS EMPTY.

The most important rule of gun cleaning isto always clean from "breech to muzzle" inthe direction of bullet travel.

There are no exceptions to this rule. Going inthe wrong direction, muzzle to breech, willdeposit powder residue and abrasive dirtfrom the barrel into the chamber and neck.The next bullet will drag this dirt, down thebarrel, and erode the bore.

OVERVIEW1. Pull a swab with CLP through the bore

to mop out any loose residue and dirt.

2. Pull a brush. Turn it to clean the neck and shoulder of the neck chamber.

3. Pull a new swab to mop the residue thebrush loosened.

4. Repeat this procedure until the swabcomes out clean.

Open the action as if you were inserting acartridge. Run the flexible cleaning rod downthe bore in the direction of the bullet travel.

After using the general purpose brush toloosen dirt in the upper receiver, wrap a swabaround the end of the brush to clean andlubricate the interior.

The swab is tied onto the forged brass tip sothe rod can be worked within the receiver untilit is clean.

Apply 3 to 5 drops of CLP to the front end othe knot in the swab.

Do not dip the swab or brush into CLP. Thiwill allow excess CLP with residue to wasinto the trigger group.

The CLP will be squeezed out of the swabwhen it enters the shoulder of the chamber.The CLP will flush ahead of the swab knoand lubricate any abrasive dirt in the bore.

The uncompressed part of the swab wilfollow and extract the CLP with the residue.

Turn the rod as you enter the locking lugsThis is the most important area of thweapon. Use the receiver brush or youfinger to force the turning swab into threcess in front of the lugs.

Continue turning the swab as it enters thechamber. This will clean out the gummbuildup at the shoulder. Pay special attentionto this area after firing blank rounds.

Continue to turn the swab as it enters theneck to clean and lubricate this area.

A brush only loosens residue and dirt. Thswab is needed in this area to mop this loosedirt from the bore.

Now that the loose residue has been cleanedout of the receiver, locking lugs, chambershoulder, and neck: clean the bore.

Do not worry about swivels, the rod rotateswithin itself. Use the "T" handle if required.

Turn the swab over and use a new surface forthe next cleaning cycle.

Pull the flexible cleaning rod out of the barrelin the direction of the bullet travel "breech tomuzzle".

Using Chamber and Bore Brushes

Assemble the short, chamber cleaning rodwith the chamber brush on one end and the"T" handle on the other end. Insert the brushinto the chamber. Turn the brush in aclockwise direction; let it feed itself into thechamber.

This will loosen the powder residue andsurface scale in the chamber and lockinglugs. Continue turning the brush as it scrubsthe shoulder. Turn and pull the brush from the

chamber.

Assemble the bore brush on the flexiblecleaning rod. Insert the rod into and down thebore.

Do not pull the brush into the bore at first.Turn the rod as the brush enters the chamberand into the neck. Scrub the shoulder of theneck.

After scrubbing the neck, pull the brush in thedirection of the bullet "breech to muzzle".

Now run the swab as described earlier, Thiswill mop out the chamber area and borewhere the brush loosened r esidue.

The most important feature of the cleaningsystem is the flexible cleaning rod. The cableconstruction limits torque on componentsThis allows brushes and swabs to follow thetwist of the rifling.

All brushes and tips can be loosened easilywith your fingers.

The neck is critical to the accuracy of thweapon. When the new round is inserted thebrass case is a few thousands of an inch fromthe throat or start of the bore. The new bullerests at the start of the throat. The bore brushis made oversize to scrub this critical area.

Obstructions

If the chamber is not maintained properlfired cases may get stuck in the chamber.The extractor pulls loose from the rim.

To remove a stuck case, run the flexible

cleaning rod into the bore and tap rapidly onthe base of the case. Eventually the stuckcase will be removed.

Clean the rifle and pay special attention to thegummy buildup at the chamber shoulder.

The obstruction remover may also be used toremove snow, mud, or other obstruction fromthe bore in operational conditions.

Push the rod down the bore in the direction ofthe muzzle. Run a swab with CLP to mop ouany remaining mud or snow.
