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.
•Firearms must be unloaded when not in use and stored in a locked location.
•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: SEMI-AUTOMATIC OPERATION

CRITICAL DISTINCTION

This rifle is a SEMI-AUTOMATIC firearm. After each shot, the gas-operated bolt carrier group cycles automatically — ejecting the spent casing and chambering the next round from the magazine. One trigger pull = one round fired. This is NOT a fully automatic firearm; the trigger must be released and pressed again to fire each subsequent round.

How Semi-Automatic Operation Works

•When you press the trigger, the rifle fires one round.
•Expanding gas from the fired cartridge is routed back through the gas system and into the bolt carrier group.
•The bolt carrier group cycles rearward, extracting and ejecting the spent casing.
•The buffer spring returns the bolt carrier forward, stripping a fresh round from the magazine and chambering it.
•The rifle is now ready to fire the next round when the trigger is pressed again.

Standard AR-15 Bolt Carrier Group

The semi-automatic ARC Rifle uses a standard mil-spec AR-15 bolt carrier group and direct gas impingement system. The bolt carrier group is interchangeable with any standard AR-15 BCG for maintenance and replacement.

Operating Cycle

1.Load Magazine: Insert a loaded magazine and chamber the first round by pulling and releasing the charging handle.
2.Aim and Fire: Aim at target, place safety on FIRE, press trigger to discharge.
3.Auto-Cycle: The bolt automatically cycles, ejecting the spent casing and chambering the next round.
4.Repeat: Release the trigger and press again to fire the next round. Continue until the magazine is empty or you stop firing.

4. COMPONENTS AND CONTROLS

The ARC Rifle maintains the familiar AR-15 platform layout with the following key controls and components.

Safety Selector

The safety lever is located on the left side of the lower receiver. Push forward to place the rifle in FIRE mode; push rearward to place the rifle in SAFE mode. Always keep the rifle on SAFE except when actively firing.

Charging Handle

The charging handle is located on the top rear of the upper receiver. Pull it fully rearward to manually cycle the bolt for the initial round chambering, clearing malfunctions, or unloading. During normal firing, the bolt cycles automatically — the charging handle is only needed to chamber the first round and to clear the rifle.

Trigger

The trigger is located inside the trigger guard. Press the trigger rearward to fire the rifle (when on FIRE and the hammer is cocked). Release the trigger fully between shots to reset the trigger for the next round. Keep your finger OFF the trigger until ready to fire.

Magazine Release

The magazine release button is located on the right side of the lower receiver just below the ejection port and above the trigger. Press to eject the magazine.

Bolt Catch / Bolt Release

The bolt catch is located on the left side of the lower receiver. After the last round in the magazine is fired, the bolt will lock to the rear. Press the upper portion of the bolt catch to release the bolt forward (with a fresh loaded magazine inserted) to chamber the next round, or press the lower portion to manually lock the bolt to the rear for inspection or unloading.

Forward Assist

Press the forward assist (top rear right of upper receiver) to ensure the bolt carrier is fully forward and locked. This is a standard feature included on all ARC rifles.

Grip-Mounted Power Switch

CRITICAL

The grip-mounted power switch controls the electronic system. The switch must be turned ON for the integrated lighting system to function and MUST be ON when charging the rifle. Always keep the switch OFF when not in use to preserve battery life. See Section 5 (Electronic System and Battery Management) for full details.

5. ELECTRONIC SYSTEM AND BATTERY MANAGEMENT

Overview

The ARC Rifle includes a fully integrated onboard power system housed in the pistol grip. This system provides power for integrated lighting. The system uses 18650 rechargeable batteries and communicates via USB-C.

Battery Specifications

•Battery type: 18650 rechargeable lithium-ion
•Location: Grip compartment (integrated—do not attempt to remove or replace)

Pogo Pin Area – Critical Care Instructions

DANGER

The pogo pin connection area is critical to rifle function. Keep this area completely dry at all times.

•DO NOT allow liquids (water, oil, solvents, or cleaning fluids) to enter the pogo pin charging area.
•The pogo pins use 24K gold plating for conductivity. Liquids can corrode connections and cause malfunction.
•Although the electronics are potted (encapsulated in protective material), some solvents may seep in over time.
•Always dry the grip area before charging and after any exposure to moisture.
•Never submerge the grip in water or cleaning solutions.

Battery Service and Replacement

⚠ IMPORTANT

The battery compartment in the grip is NOT serviceable by the customer. DO NOT attempt to open the grip or remove the battery. If the battery requires service, replacement, or if you experience battery-related issues, the entire grip assembly must be sent back to Law Weapons Inc. for factory service. 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, keep the rifle well lubricated. After 200 rounds, the rifle should cycle smoothly and reliably.

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.
Lock the bolt to the rear using the bolt catch.
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 SEMI-AUTOMATIC rifle. After chambering the first round, the rifle will cycle automatically between shots. One trigger press = one round fired.

Step 1: Load the Magazine

•Load 5.56 NATO ammunition into a standard AR-15 magazine, observing your local legal capacity limits.
•Verify your jurisdiction's magazine capacity restrictions before loading.

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: Semi-Automatic Cycling

THE BOLT CYCLES AUTOMATICALLY — NO MANUAL ACTION REQUIRED BETWEEN SHOTS.

•After firing, gas pressure cycles the bolt carrier rearward, ejecting the spent casing.
•The buffer spring returns the bolt carrier forward, stripping a fresh round from the magazine and chambering it.
•The rifle is ready to fire again. Release the trigger fully to reset, then press again to fire the next round.
•When the last round is fired, the bolt will lock to the rear (bolt hold-open). Insert a fresh magazine and press the bolt release to resume firing.

Step 6: Cease Fire

When you are finished shooting, move the safety to SAFE, remove the magazine, lock the bolt to the rear, and visually inspect the chamber to confirm it is empty.

Clearing a Double Feed or Jam

•If the rifle fails to cycle, stop immediately.
•Point the muzzle in a safe direction.
•Place the safety on SAFE.
•Remove the magazine by pressing the magazine release button.
•Pull the charging handle fully rearward and lock the bolt back. Inspect the chamber for an unfired or partially-fed round.
•If a round is stuck, carefully extract it. Do not force the bolt. Contact Law Weapons Inc. if you cannot safely clear the malfunction.
•Once cleared, visually inspect the chamber, magazine, and ammunition for debris or damage before reloading.

8. MAINTENANCE AND CLEANING

Regular maintenance and cleaning will keep your ARC Rifle 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 bolt carrier group, gas key, and firing pin for excessive wear.
•Reassemble, lubricate, and function test.

Field Stripping the Rifle

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, gas key, 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.
