TABLE OF CONTENTS
1. SAFETY WARNINGS AND PRECAUTIONS
Read, understand, and follow all instructions and safety warnings in this manual before operating this firearm. Your safety and the safety of those around you depends on your knowledge of this rifle and your understanding of firearm safety guidelines common to all firearms.
⚠ DANGER: SERIOUS INJURY OR DEATH
- •Treat every firearm as if it is loaded at all times.
- •Keep the muzzle pointed in a safe direction at all times. Never point the firearm at anything you do not intend to shoot.
- •Keep your finger OFF the trigger until you are ready to fire the rifle.
- •Be absolutely certain of your target and what is beyond it before firing.
- •Store this firearm in a secure location away from unauthorized users, especially children.

- •Never alter or modify this firearm in any way except as specifically authorized in this manual.
- •A dropped firearm may discharge. Always handle with care.
- •Do not use defective ammunition. Inspect all ammunition before loading.
⚠ WARNING: POTENTIAL FOR INJURY
- •Failure to follow these instructions may result in injury or death.
- •In case of a misfire or failure to fire, keep the muzzle pointed in a safe direction for at least 30 seconds before carefully unloading the round.
- •Wear appropriate eye and hearing protection when firing this rifle.
2. IMPORTANT FEATURES: MANUALLY OPERATED BOLT ACTION
CRITICAL DISTINCTION
This rifle is NOT a semi-automatic firearm. The ARC M.O.B.A is a MANUALLY OPERATED BOLT ACTION rifle designed for compliance with Illinois firearm regulations.
What This Means
- •After each shot, you must MANUALLY pull back the charging handle to rack the next round into the chamber.
- •The bolt will NOT cycle automatically. This is intentional and required for Illinois legal compliance.
- •You control the rate of fire entirely—it is your manual action that cycles the bolt.
- •This makes the ARC M.O.B.A a bolt action rifle under Illinois law.
LAW BOLT 15 System
This rifle is equipped with a LAW BOLT 15 (Legally Authorized Weapon Bolt 15), a proprietary manually operated bolt system. Because it is not a semi-automatic rifle and is sold as a bolt action rifle.
Operating Cycle
- 1.Magazine and Load: Insert loaded magazine and manually chamber the first round by pulling the charging handle.
- 2.Aim and Fire: Aim at target, place safety on FIRE, press trigger to discharge.
- 3.Manually Recycle: BEFORE firing again, pull the charging handle fully rearward to eject the spent casing and chamber the next round.
- 4.Repeat: Aim, press trigger, manually recycle bolt—each shot requires this deliberate sequence.

Attempting to disassemble the grip may damage the electronic system and void your warranty.
6. SAFE HANDLING AND OPERATION
Break-In Period
IMPORTANT
This is a new rifle and requires a break-in period of 200 rounds. During break-in, the charging handle may be more difficult to operate. Keep the rifle well lubricated during this period. After 200 rounds, the rifle should operate smoothly.
Before Every Use
- •Visually inspect the rifle for damage, cracks, or loose components.
- •Ensure the barrel is clear of obstructions (look through the barrel from the rear in a safe direction).
- •Verify that the safety is in the SAFE position.
- •Verify that the rifle is unloaded (no magazine inserted, no round in the chamber).
Unloading the Rifle
- Point the muzzle in a safe direction.
- Place the safety in the SAFE position.
- Press the magazine release button and remove the magazine.
- Pull the charging handle fully rearward to eject any round in the chamber.
- Visually and physically inspect the chamber to confirm it is empty.
Handling a Misfire or Failure to Fire
If you press the trigger and the rifle does not fire, IMMEDIATELY point the muzzle in a safe direction and wait at least 30 seconds. A hangfire (slow ignition) may occur. After 30 seconds, if the round has not fired, carefully unload the round as described above.
Ammunition Safety
- •This rifle is chambered in 5.56 NATO / .223 Remington. Use only ammunition in this caliber.
- •NEVER use other calibers—this can result in injury or death.
- •Inspect ammunition before loading. Do not use damaged, corroded, or defective rounds.
- •Store ammunition in a cool, dry location away from moisture and extreme temperatures.
7. LOADING AND FIRING
The Firing Sequence
Remember: This is a MANUALLY OPERATED BOLT ACTION rifle. Each shot requires deliberate manual action to chamber the next round.
Step 1: Load the Magazine
- •Load 5.56 NATO ammunition into a standard AR-15 magazine (up to the magazine's capacity or per your local legal limit).
- •For this manual, we assume Illinois legal magazine limits; verify your local requirements before operating this rifle.
Step 2: Insert the Magazine
- •Ensure the safety is in SAFE.
- •Align the magazine with the magazine well (bottom of the lower receiver).
- •Insert the magazine upward at a slight forward angle, then snap it firmly into place. It should click and sit flush with the lower receiver.
Step 3: Chamber the First Round
- •Locate the charging handle on the upper receiver (top rear, extends slightly backward).
- •Firmly grasp the charging handle and pull it fully rearward (toward you). You will feel resistance as the bolt carrier moves back.
- •Release the charging handle. The bolt carrier will spring forward, chambering the first round from the magazine.
- •The rifle is now ready to fire. Keep the safety on SAFE until you are ready to shoot.
Step 4: Aim and Fire
- •Assume a stable shooting position (standing, kneeling, prone, or supported).
- •Acquire your target through the sights or optics.
- •Verify that nothing is beyond your target that could be harmed by a miss or overpenetration.
- •Move the safety to FIRE.
- •Place your finger on the trigger (not before—keep it off the trigger until this moment).
- •Press the trigger smoothly to the rear. The rifle will fire.
Step 5: Manually Recycle the Bolt (The Critical Difference)
BEFORE YOU CAN FIRE AGAIN, YOU MUST MANUALLY PULL THE CHARGING HANDLE TO CHAMBER THE NEXT ROUND.
- •After the round fires, the bolt will remain in the forward position.
- •Pull the charging handle fully rearward again. You may feel a slight bump as the bolt carrier reaches full travel ejecting the spent casing.
- •Release the charging handle—do not walk it forward, let the spring power do the work. It will spring forward, chambering the next round.
- •The rifle is now ready for your next shot. Aim and repeat the firing sequence.
Step 6: Repeat
Continue this cycle for each subsequent shot: Manually cycle the charging handle → Aim → Fire. The rate of fire is entirely under your control via manual bolt operation.
Clearing a Double Feed or Jam
- •If you feel severe resistance when pulling the charging handle or suspect a jam, stop immediately.
- •Point the muzzle in a safe direction.
- •Place the safety on SAFE.
- •Remove the magazine by pressing the magazine release button.
- •Try to gently work the charging handle backward. If resistance is severe, contact Law Weapons Inc. for assistance.
- •Once cleared, visually inspect the chamber and magazine for debris or damaged ammunition.
8. MAINTENANCE AND CLEANING
Regular maintenance and cleaning will keep your ARC M.O.B.A in excellent working condition. Follow standard AR-15 maintenance practices with special attention to the electronic system.
Basic Maintenance Schedule
After Every Use:
- •Unload the rifle completely.
- •Visually inspect the barrel, receiver, and bolt carrier for debris or fouling.
- •Store in a cool, dry location.
Monthly or Every 500 Rounds (whichever comes first):
- •Field strip the rifle (see below).
- •Clean all parts with a brush and dry cloth.
- •Inspect the charging handle, bolt carrier, and firing pin for excessive wear.
- •Reassemble, lubricate, and function test.
Field Stripping the Rifle
Field stripping means partial disassembly for cleaning. This is the only disassembly recommended for user maintenance.

1. Remove Magazine and Unload:
Press the magazine release button and remove the magazine. Pull the charging handle to eject any round in the chamber. Visually inspect the chamber to confirm it is empty.
2. Release the Receivers: Figures 1 and 2
Locate the two takedown pins (front and rear) on the left side of the rifle. Using a small pin punch or drift, gently push each pin from left to right. The pins are captured—they will move but not fully separate from the rifle. Once pushed to the right, the upper receiver can be separated from the lower receiver.
3. Remove the Bolt Carrier Group: Figure 3
From the upper receiver, pull the bolt carrier assembly rearward and out of the upper receiver. The charging handle will come out with it.
4. Remove the Bolt: Figure 4
The bolt can be pushed out of the bolt carrier (push from the rear). However, detailed disassembly of the bolt carrier beyond removal is not recommended without proper tools.
5. Clean Components:
Using a soft brush and dry cloth, clean all components. Pay special attention to the bolt, bolt carrier, chamber, and barrel interior. A bore brush and rod can be used to clean inside the barrel.
Cleaning Materials
- •Soft brass brush (for bore cleaning)
- •Cleaning rod and jag
- •Dry cloth or lint-free towel
- •Break-in cleaner or degreaser (for heavy fouling)
- •Lubricating oil (light machine oil or gun oil)
- •Small pin punch (1/16" or 3/32") for takedown pins
⚠ CRITICAL: PROTECT THE ELECTRONIC SYSTEM
When cleaning the rifle, avoid getting liquids (oil, solvents, or water) on the grip or near the charging port area. The electronic system is potted, but excessive exposure to solvents or moisture can cause corrosion of the pogo pin contacts and compromise system function.
- •Keep the grip area DRY and clean of solvents.
- •Do NOT submerge the grip in cleaning solutions.
- •If liquid does contact the grip area, allow it to air dry completely before charging or using the rifle.
Lubrication
Light lubrication of the bolt carrier and moving parts is recommended after cleaning. Use a quality gun oil or light machine oil. Apply sparingly—excess oil will collect dirt. Do not lubricate the barrel interior or firing pin.
Reassembly
1. Reassemble the Bolt Carrier Group:
Reinsert the bolt into the bolt carrier (push from the rear until it seats completely).
2. Insert into Upper Receiver:
Slide the bolt carrier assembly back into the upper receiver. The charging handle should align and pull smoothly.
3. Mate Receivers:
Align the upper and lower receivers and push together until they are flush.
4. Reinstall Takedown Pins:
Using the pin punch, gently push the front takedown pin from left to right until it is flush with the right side of the receiver. The pin will not fully separate. Repeat with the rear takedown pin. Both pins should be fully seated.
5. Function Test:
Ensure the safety is in SAFE. Pull the charging handle—it should move smoothly without binding. Release it—the bolt carrier should snap forward cleanly. Verify the trigger functions normally (DO NOT fire for this test; just press and release the trigger). If any binding or resistance is felt, disassemble and inspect for dirt or misalignment.
9. TROUBLESHOOTING
| Problem | Possible Causes | Solution |
|---|---|---|
| Failure to Fire | Safety on SAFE; no round chambered; defective ammunition; light primer strike | Ensure safety is on FIRE. Check that a round is chambered (pull charging handle). Inspect ammunition. Try new ammunition. If problem persists, contact factory. |
| Failure to Eject | Fouling in chamber or ejector; dirty bolt carrier | Field strip rifle. Clean chamber, bolt, and ejector. Ensure ejector spring is functioning. Contact factory if problem persists. |
| Hard Charging Handle (beyond break-in) | Fouling; debris in bolt carrier tracks; dry bolt carrier | Field strip and clean all components. Apply light oil to bolt carrier and rails. Do not force the charging handle. |
| Magazine Won't Lock In | Damaged magazine catch; debris in magazine well; magazine feed lips damaged | Try different magazine. Clean magazine well. Inspect magazine for damage. If magazine catch is broken, contact factory. |
| Lighting Not Working | Power switch off; battery depleted; corrosion on pogo pins | Check grip power switch is ON. Charge the rifle using included charger. Inspect pogo pins for corrosion. Dry grip area if wet. Contact factory if battery needs replacement. |
| Won't Charge | Power switch off; corrosion on pogo pins; faulty charger | Ensure power switch is ON. Dry grip and charger connector. Use only the included charger. Try different power outlet. Contact factory for battery service. |
