  1. Review the chart above to see what washer spacer configuration works best with your caliber. Place the selected number of #10 washers in each cavity followed by an O-ring.



  1. Insert the two 10-24 x ⅞” hex screws through the polymer body assembly with a #10 washer under each screw head. Note - It is recommended that Loctite Threadlocker Blue 242 be applied to each 10-24 x ⅞” hex screw end. It is important to be aware of the side which the screwheads are on, as this dictates the side of the chassis it is installed onto. Please refer to the diagram below:

  1. Insert the M-LOK interface plate onto the 10-24 x ⅞” screw ends with the circular bosses facing towards the 2 Round Holder. Once pressed on the interface plate should sit flush on the surface of the 2 Round Holder.

                         
  2. ACC Chassis Installation - Align the 2 Round Holder assembly so the M-LOK interface plate is facing the chassis and the logo is right side up. Press the assembly into the two integral mounting pockets located on the side of the chassis behind the first M-LOK slot.

    Place two loose cartridges in the 2 Round Holder and tighten the two 10-24 x ⅞” mounting screws until snug and desired round retention is achieved.









M-LOK Slot Installation - Thread the two M-LOK nuts provided onto each 10-24 x ⅞” screw one full rotation. Align the 2 Round Holder assembly so the M-LOK interface plate is facing the chassis and the logo is right side up. Press the assembly into the desired M-LOK slots so the interface plate bosses are captured within the slot.

Place two loose cartridges in the 2 Round Holder and tighten the two 10-24 x ⅞” mounting screws until snug and desired round retention is achieved. Ensure the M-LOK nuts rotate and lock on the inside forend channel.

  SAFETY GUIDELINES

 

1. ALWAYS KEEP THE MUZZLE POINTED IN A SAFE DIRECTION.

Never allow your firearm to point at anything you do not intend to shoot. Always handle any firearm as if it were loaded and ready to shoot. UNLOAD ALL FIREARMS WHEN NOT IN USE. ALWAYS VERIFY. Load your firearm only when you are in the field or on the target range and ready to fire. Unload as soon as you finish shooting. Verify that the firearm is unloaded before storing and ALWAYS when you pick it up.

 

2. DO NOT RELY ON ANY MECHANICAL SAFETY.

Safety devices are not a substitute for safe handling procedures. Treat every firearm as if it can fire at any time, regardless of the safety position. Do not touch the trigger until you are ready to fire.

 

3. UNDERSTAND THE TARGET AND WHAT IS BEYOND THE TARGET.

Do not fire unless you know exactly where your shot is going, and what is beyond the expected point of impact. Never fire at a sound, a movement, or a patch of color. If you cannot see clearly what is beyond the target, DO NOT SHOOT.

 

4. NEVER SHOOT AT WATER OR AT A HARD SURFACE.

Shooting at water, rocks, or other hard surfaces may result in bullet fragmentation with unpredictable flight paths.

 

5. USE PROPER AMMUNITION.

The use of wrong ammunition, mixed ammunition, or improperly reloaded ammunition may result in serious injuries or death, and catastrophic damage to your firearm. Check each round before loading. If in doubt, DO NOT SHOOT.

 

6. IF THE FIREARM FAILS TO FIRE, DO NOT MOVE.

If the ammunition does not fire when you pull the trigger, stop and keep the muzzle pointed in a safe direction. Wait 15 seconds before opening the chamber. Look away from the chamber while opening it and removing the round. In semi-automatic firearms, remove the magazine before manually cycling the round. Properly discard the round immediately. DO NOT try to fire it again.

 

7. ALWAYS WEAR EYE AND EAR PROTECTION WHEN SHOOTING.

Wear protective shooting glasses to guard against any combustion discharges, cartridges ejection, or debris resulting from firing your firearm or firearms around you. Also, wear eye protection when you are disassembling or cleaning a firearm to guard against tensioned parts and cleaning solvents. Always use ear protection.

 

8. VERIFY THAT ACTION AND BARREL ARE CLEAR BEFORE SHOOTING.

Before loading your gun, inspect the action and barrel to ensure there are no obstructions such as snow, mud, excess lubricant, cleaning patches, or any other foreign material.

 

9. LEARN THE PARTICULAR CHARACTERISTICS OF EACH FIREARM.

Not all firearms are alike. Become very familiar with the firearm before shooting. Learn safe handling procedures for loading, unloading, carrying, shooting and storing each firearm before firing the first round.

 

10. SHOOT SOBER!

NEVER handle any firearm while under the influence of alcohol, drugs, or any medication that may impair your senses in any form.
