Raven Tunable Adjustable Buffer Installation

STOP!!

YOU MUST ENSURE YOUR FIREARM IS FULLY UNLOADED AND PROVED SAFE BEFORE USING!!

PROVE
POINT THE FIREARM IN THE SAFEST AVAILABLE DIRECTION.
REMOVE ALL AMMUNITION.

OBSERVE THE CHAMBER.
VERIFY THE FEEDING PATH.
EXAMINE THE BORE.

ONCE SAFE, YOU MAY PROCEED TO THE NEXT STEP.

WEIGHT CODES AND THEIR WEIGHTS:
W (TUNGSTEN) 1.5 OZ
SS (STAINLESS) 0.7 OZ
AL (ALUMINUM) 0.2 OZ



USE WITH PISTOL CALIBERS - BLOW-BACK SYSTEM
COMES WITH 2 ALUMINUM, 2 STAINLESS STEEL AND 4 TUNGSTEN WEIGHTS ADJUSTABLE FROM (4.6OZ - 11OZ)


TIP: BLOW-BACK FIREARMS RELY ON HEAVY BUFFER WEIGHTS TO KEEP THE FIRING BOLT IN BATTERY LONG ENOUGH TO SAFELY FIRE THE CARTRIDGE. HAVING TOO LIGHT OF WEIGHT CAN CAUSE SERIOUS SAFETY CONCERNS WHICH CAN CAUSE DAMAGE TO YOUR FIREARM OR SERIOUS BODILY HARM! IF YOU DO NOT KNOW WHAT YOU DO ARE DOING, STOP!


WE DO NOT RECOMMEND GOING BELOW 7.0 OZ UNLESS YOU KNOW WHAT YOU ARE DOING. BY CHANGING THE WEIGHTS, YOU ARE ADJUSTING HOW YOUR FIREARM CYCLES. MORE WEIGHT, MEANS THE BOLT REMAINS IN BATTERY FOR LONGER. INCREASING THE WEIGHT CAN ALSO PROVIDE
NOTICEABLE BENEFITS, INCLUDING REDUCING FELT RECOIL, MUZZLE MOVEMENT, AND PROVIDING ADDITIONAL MASS TO AID FEEDING.


DEPENDING ON THE EXACT GRAINS
AND CALIBER THAT YOU ARE SHOOTING, YOU CAN TUNE YOUR RIFLE BUFFER TO FUNCTION OPTIMALLY.


HOWEVER IF THE BUFFER WEIGHT IS TOO LOW FOR THE GRAINS AND CALIBER YOU ARE FIRING, THE FIRING BOLT MAY START TO CYCLE REARWARD TOO EARLY IN THE FIRING SEQUENCE, CAUSING THE CARTRIDGE TO POTENTIALLY FIRE PARTIALLY OUT OF BATTERY CAUSING SERIOUS INJURY OR DEATH.


TOO LIGHT OF A WEIGHT ALSO MEANS THE BOLT WILL BE TRAVELING REARWARD AT A HIGHER VELOCITY, AND THE CYCLE WILL BE MUCH FASTER. IF THE CYCLING TIME IS TOO FAST, THE LAST ROUND BOLT HOLD OPEN FEATURE MAY NOT HAVE TO ENGAGE. TO CORRECT THIS, SIMPLY ADD MORE MASS, WHICH WILL SLOW DOWN THE CYCLING RATE AND GIVE THE BOLT CATCH TIME TO ENGAGE. IF THE FIRING BOLT IS CYCLING TOO FAST IT CAN CAUSE ADDED STRAIN AND DAMAGE TO THE BUFFER WEIGHT AND THE BUFFER TUBE.


RELOADING YOUR OWN AMMUNITION CAN BE DANGEROUS. SIMILARILY, ADJUSTING YOUR BUFFER WEIGHTS CAN ALSO BE DANGEROUS AND CAUSE NEGITIVE EFFECTS. ENSURE YOU KNOW WHAT YOU ARE DOING AND VERIFY YOUR CHANGES PRIOR TO LIVE FIRING! DO NOT HAVE TOO LIGHT OF A BUFFER WEIGHT FOR THE CALIBERS YOU ARE SHOOTING!


USE WITH RIFLE CALIBERS - DIRECT IMPINGEMENT
COMES WITH 2 ALUMINUM, 2 STAINLESS STEEL AND 2 TUNGSTEN WEIGHTS
ADJUSTABLE FROM (2.5OZ - 6.2OZ)


OPPOSITE TO A BLOW-BACK SYSTEM, DIRECT INPINGEMENT SYSTEMS RELY ON GAS PRESSURE COMING THROUGH THE BARREL, THROUGH THE GAS BLOCK, CARRYING ON THROUGH THE GAS TUBE AND PUSHING ON THE FIRING BOLT CARRIER TO UNLOCK THE BOLT FROM IT'S IN BATTERY POSITION. ONCE THE BOLT IS UNLOCKED IT TRAVELS REARWARD UNDER MUCH LOWER PRESSURES THAN IN A BLOW-BACK.


DURING THE REARWARD CYCLING, IT EXTRACTS AND EJECTS THE SPENT CASING, THE SAME WAY AS A BLOW-BACK SYSTEM WOULD.


THE BIGGEST DIFFERENCE TO BUFFER WEIGHTS IN A DIRECT IMPINGEMENT SYSTEM IS THAT THE BOLT IS LOCKED INTO THE CHAMBER DURING THE INTENSE FIRING SEQUENCE. DUE TO THIS "LOCKED IN" NATURE, ONCE THE GAS PRESSURE COMES THROUGH THE GAS TUBE AND PUSHES ON THE BOLT CARRIER TO RELEASE IT, MUCH OF THE FIRING FORCE HAS ALREADY DISSIPATED. BECAUSE OF THIS, THE BUFFER WEIGHT CAN BE SIGNIFICANTLY LIGHTER THAN THAT OF A BLOW-BACK.


DEPENDING ON THE WEIGHT OF THE BUFFER, IT CAN HELP ABSORB SOME OF THE RECOIL. THIS PROVIDES A SMOOTHER CYCLE OF THE BOLT GOING BACK AND FORTH, AND CREATES A BETTER SHOOTING EXPERIENCE WITH FASTER FOLLOW-UP SHOTS. HEAVIER BUFFERS ALSO HELP REDUCE WEAR AND TEAR ON YOUR FIREARM.


TYPICALLY A 5.56 RIFLE WOULD HAVE A BUFFER WEIGHT OF AROUND 3.0 OZ
ADJUSTING THE WEIGHT TO A HEAVIER BUFFER OF 3.8 OZ IS 25% HEAVIER AND REDUCES PERCEIVED FELT RECOIL AND REDUCES WEAR ON YOUR FIREARM.


WHEN ADJUSTING YOUR BUFFER WEIGHTS, IF THE BOLT CARRIER STILL FEELS LIKE IT’S CYCLING TOO HARD, WE RECOMMEND ADDING MORE BUFFER WEIGHT TO GET THE RIFLE SHOOTING SOFTER.


HAVING AN ADJUSTABLE GAS BLOCK ON A DIRECT IMPINGEMENT FIRING STYLE ALLOWS YOU TO ALLOW TUNE THE AMOUNT OF GAS PRESSURE PUSHING ON THE FIRING BOLT. YOU SHOULD AJUST THE GAS PRESSURE TO BE AS LOW AS POSSIBLE, WHILE STILL ENSURING THE FIREARM CYCLES PROPERLY BETWEEN SHOTS.


A SIMPLE WAY TO TEST IF THE CYCLING IS HAPPENING PROPERLY IS TO LOAD MULTIPLE MAGAZINES WITH 2 ROUNDS. LOAD AND FIRE THE FIRST ROUND.
IF THE BOLT DOES NOT CYCLE REARWARD ENOUGH TO PICK UP AND LOAD THE SECOND ROUND IN THE CHAMBER, THEN THE GAS PRESSURE IS TOO LOW. SIMPLY ADJUST THE PRESSURE TO BE SLIGHTLY HIGHER. CONTINUE TO ADJUST IN SMALL INCREMENTS UNTIL THE RIFLE RELIABLY PICKS UP THE SECOND ROUND.


AFTER THE SECOND ROUND IS FIRED, THE BOLT CATCH SHOULD AUTOMATIALLY ENGAGE. IF THE BOLT CATCH IS NOT ENGAGING, EITHER THE BOLT IS STILL NOT CYCLING REARWARD ENOUGH (IN WHICH CASE, MORE GAS PRESSURE IS NEEDED), OR YOU ALLOWED TOO MUCH GAS PRESSURE TO PUSH ON THE BOLT WHICH IS CAUSING IT TO CYCLE TOO QUICKLY FOR THE BOLT CATCH TO ENGAGE. IF THAT IS THE CASE, ADJUST THE GAS PRESSURE TO BE LOWER UNTIL THE BOLT CATCH WORKS. IT'S BEST TO START WITH THE GAS BLOCK FULLY TURNED OFF, THEN ADJUST WITH VERY SMALL INCREMENTS UNTIL YOU ARE HAPPY WITH IT'S OPERATION.
