INSTALLATION OF THE SRS LITE V2
1. Ensure the firearm is unloaded;
2. Remove the magazine and bolt;
3. Remove the current buttstock;
4. Screw the included mini buffer tube into your chassis, and tighten using a crescent wrench or ⅝” wrench;
5. Slide the SRS Lite V2 over the mini buffer tube;
6. Thread the included ¼” socket head cap screw through the buttstock into the mini buffer tube. Apply modest force and screw the
screw an additional quarter-rotation; this will clamp the stock onto the buffer tube.
ADJUSTING THE CHEEKRISER POSITION
1. To adjust the cheek-riser height, loosen the two ¼-20 brass tipped set screws on the side of the buttstock using a ⅛” hex allen key.
2. Move the cheek-riser to the desired location.
3. Re-tighten the two 1/4-20 brass tipped set screws.
ADJUSTING THE LENGTH OF PULL (LOP)
1. To adjust the LOP, loosen the two #10-32 socket head cap screws in the back of the buttpad. This will allow you to move the buttpad
backwards and create space to add or remove a spacer.
2. To add spacers, first ensure that all existing spacers are pressed forward, creating a space directly in front of the buttpad. .
3. Position the spacer slot onto the bottom screw. There will be a slight click as the screw goes into its required spot
4. Pivot the spacer about the screw to engage the second screw.
5. Re-tighten the #10-32 screws.

1. ALWAYS KEEP THE MUZZLE POINTED IN A SAFE DIRECTION.
UNLOAD ALL FIREARMS WHEN NOT IN USE. ALWAYS VERIFY. 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. 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.
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 surface 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.
