Your JS Gunworks firearm will perform better, last longer and remain safer when it is properly maintained. Follow the instructions in this section to keep your firearm in good condition.
1. MAKE SURE THAT THE MAGAZINE IS REMOVED AND THAT THE FIREARM IS UNLOADED SO THAT IT CANNOT BE FIRED.
2. WEAR SAFETY GLASSES IN CASE YOU LOSE CONTROL OF ANY SPRING LOADED COMPONENTS WHICH COULD INJURE YOUR EYES.
IMPORTANT: To prevent loss of small components during stripping and cleaning, lay them out in an orderly fashion.
1. Read safety instructions in Section 3 and previous CAUTIONS.
2. Press the rear take down pin in from the left hand side of lower receiver and pull the pin out on the right hand side of the receiver until it comes to a positive stop.
3. Pivot the lower receiver down and away from the upper receiver.
4. If required for more convenience, completely separate the upper receiver from the lower receiver by pressing the front take down pin from the left hand side of the lower receiver and pulling out the pin on the right hand side of the receiver until it comes to a positive stop.
5. Pull charging handle to rear and remove the bolt carrier group.
6. Remove the charging handle by pulling it backwards the keyway and then down and out of the upper receiver.
7. Push in the firing pin retaining pin from right to left of the bolt carrier group and remove the pin by pulling it out to the left.
8. Tilt the bolt face up and remove the firing pin.
9. Push the bolt in towards the carrier until bolt rotates and comes to a stop, then turn the bolt cam pin through 90 (i.e., at right angles to its normal position.
10. Remove the cam pin by lifting it out and away from the bolt and bolt carrier.
11. Pull the bolt forward and remove it from the bolt carrier.
12. Depress the buffer, maintaining pressure as the buffer is under spring tension, to prevent it from being ejected when the buffer retainer pin is depressed.
13. Depress the buffer retainer pin to permit the buffer and the action spring to move forward. Depress the hammer to allow the action spring and the buffer assembly to continue moving forward and be completely removed from the receiver extension.
1. Remove the 2 hex head screws that secure the rail to the barrel nut.
2. With the screws out, remove the rail system by pulling forward towards the end of the barrel.
Note: Removal not necessary unless replacing gas block/ gas tube combo
Note: On reassembly, suggest cleaning threads, add a dab of blue Loctite, and torque to 35 in-lbs.
Do not strip your firearm further than previously described. If additional maintenance is required, see "Service and Repair" later in this instruction manual. Reassemble your firearm by reversing the stripping procedure already described, and make sure that the cam pin is properly installed.
Before firing, make sure that the barrel and the chamber are clean and dry.
After firing, clean your firearm as soon as possible so that the job will be easier and there will be less opportunity for corrosion to start.
Periodically, when your firearm has not been fired, we suggest you clean it when necessary and at least once or twice a year in a temperate climate, or as often as once a week in a tropical climate. If you carry a loaded firearm UNLOAD it and clean it when necessary and at least once a month. If you get your firearm wet, clean it as soon as possible.
The following cleaning procedure may be used both periodically and after firing; however, those items marked with a “*" are unnecessary for periodic cleaning.
Materials: Cleaning rod, cleaning patches (cut to fit snugly into the bore), a small nylon brush, good quality light gun oil, *gun cleaning solution, * a brass wire bristle bore cleaning brush, and a chamber cleaning brush. Procedure:
1. Strip for cleaning as previously described. Note: Avoid contact between the cleaning rod and the muzzle as resultant wear will greatly reduce accuracy.
2. Attach a cotton flannel patch to end of the cleaning rod, insert it in the chamber and pass the rod and patch down through the barrel. Repeat, changing patches with each pass through the barrel, until the last patch comes out clean.
3. Visually inspect the barrel; if it is clean, proceed directly with step 8, but if it remains dirty, continue with step 5.
4. *(Note: Items 5 & 6 should be applicable only after firing.) Attach brass wire bristle bore cleaning brush to cleaning rod and dip brush in firearm cleaning solution. Thoroughly scrub out barrel, passing the brush all the way through before reversing the movement. If you try to change direction with the brush in barrel, the brush will stick.
5. Attach the larger, chamber cleaning brush to the cleaning rod, dip the brush in bore cleaning solution, and clean the chamber. Use a minimum of five plunge strokes and three 360 clockwise, rotational strokes.
6. Repeat steps 3 and 4 above.
7. Use bore cleaning brush, still wet with firearm cleaning solution, and clean all carbon and powder residue from around the gas tube in the upper receiver, bolt locking lugs, bolt rings, firing pin, bolt cam pin, lip of the extractor, and inside the bolt carrier group. If any of these conditions are discovered, have them corrected before firing again. (See Servicing and Repair later on in this section.) IMPORTANT: Do not use a wire brush on aluminum surfaces such as the upper and lower receivers and the handguards.If cleaning is necessary, avoid scratches and wear by using a small nylon brush or flannel patch.
8. Wipe all components clean and dry and inspect them for excessive wear, corrosion or mechanical damage. If any of these conditions are discovered, have them corrected before firing again. (See Servicing and Repair later on in this section.)
9. Lightly dampen a flannel patch with gun oil and pass it once through the barrel, leaving a thin film of oil on the inside surface. Leave this film of oil on the surface if firearm is to be stored. If it is not be stored, or if it is being removed from storage for use, pass the dry patch through the barrel and chamber to remove as much oil as possible.
10. Check that flannel or brush bristles have not become lodged in any part of firearm, then lightly lubricate the following parts:
11. Reassemble the firearm as previously described.
12. Remove any gun cleaning solution, oil, and finger prints from the outside surfaces of the firearm. (Finger moisture, if left, could start a corrosion process.)
ALWAYS UNLOAD YOUR FIREARM FOR STORAGE AND STORE AMMUNITION SEPARATELY. Store your firearm and ammunition securely locked in separate locations out of reach and sight of children. (Children are naturally curious and do not always believe or understand the real danger and responsibilities of firearms.) Note: Do not store your firearm in an air tight container, and do not seal or attempt to seal the barrel to exclude dust, as internal steel surface is more likely to corrode.
Should your firearm require adjustment or repair, contact JS Gunworks, and you will receive shipping instructions. For spare parts, seek advice from the dealer/manufacturer who should have up-to-date information on how to best obtain genuine parts. Parts should be installed by JS Gunworks or by a competent gunsmith.
