WE SELL AIMPOINTS AND FIVE DIFFERENT BRANDS OF AIMPOINT MOUNTS.

THE AIMPOINT QRP WITH SPACER AND ARMS #22M68 WITH SPACER SELL FOR ABOUT THE SAME MONEY.

IT'S A NO-BRAINER. GET THE ARMS #22M68 WITH FULL SPACER, CLEARLY THE SUPERIOR CHOICE.

THE ARMS #22M68 WITH FULL SPACER WILL SET THE AXIS OF THE AIMPOINT APPROX 1.55" ABOVE THE FLAT TOP. THIS SHOULD WORK OUT ESPECIALLY WELL WITH THE FIXED STOCK. PLUS, THE MODULARITY MAY BECOME USEFUL IN THE FUTURE.

THE ARMS #22 HIGH RINGS ARE 1.45" ON CENTER, A BIT LOW WITH BACK UP IRON SIGHTS. A SINGLE RING IS NOT NEARLY AS RIGID AS THE ARMS #22M68, WHICH HAS MANY TIMES THE FOOTPRINT OR FOUNDATION ON THE RAIL.

THANKS FOR THE KIND WORDS. PAUL AND I APPRECIATE YOUR BUSINESS.

LET ME TRY TO ANSWER YOUR QUESTIONS:

1. YOUR ASSUMPTION IS INCORRECT. THE SIZE OF THE "FOOT" CAMMED BY THE THROW LEVER ON THE ARMS BASE BASE COMPARED TO THE SAME DEVICE ON THE KNIGHT'S STRAIGHT MOUNT THAT UTILIZES THE HEX NUT OR OPTIONAL THUMB NUT FOR TENSION IS INDEED A VARIABLE IN THE EQUATION, BUT DO NOT FORGET ABOUT:

  A. THE WIDTH OF THE OPPOSITE SIDE               OF THE MOUNT.
  B. THE AMOUNT OF TENSION APPLIED TO THE CROSSBOLT WHEN THE MOUNT IS INSTALLED.
  C. THE DEGREE TO WHICH THE MOUNT ACTUALLY FITS SNUGLY AT ALL CONTACT POINTS WITH THE UPPER RECEIVER. THIS IS A FUNCTION OF BOTH THE MOUNT AND THE RECEIVER.
  D. THE QUALITY OF THE MATERIALS USED TO CONSTRUCT THE MOUNT ALSO PLAYS A PART.

FORTUNATELY, WITH C. AND D., YOU HAVE NOTHING TO WORRY ABOUT WITH THESE TWO MANUFACTURERS.

BOTH THE KNIGHT'S AND THE ARMS MOUNTS GIVE A SUPERB FIT ON A COLT M4A1 UPPER. PLUS THEY HAVE SQUARE SHOULDERED CROSSBOLTS THAT ACHIEVE AN IDEAL FIT WITHIN THE RAIL SLOT, WITH POSITIVE CONTACT.

THE KAC  MOUNT FOOT IS 5/8" WHILE THE OPPOSITE SIDE IS 1" ON THE STRAIGHT AND 1 1/2" ON THE OFFSET. THE ARMS FOOT IS JUST UNDER 1/2" WHILE THE OPPOSING SIDE CONTACTS 2 3/8".

FROM AN STRUCTURAL POINT OF VIEW, I SEE THE KAC OFFSET AND GG&G CANTILEVER AS BEING THE MOST FRAGILE OF ALL OF THE AIMPOINT MOUNTS, DUE TO THE LONG MOMENT ARM PRESENTED BY THE OFFSET ARM. I HAVE USED BOTH EXTENSIVELY AND HAVE EXPERIENCED FRANKLY AMAZING RETURN TO ZERO PROPERTIES WITH BOTH, AS WELL AS WITH THE ARMS #22M68. SAME GOES FOR THE PRI, A VERITABLE TANK OF A MOUNT.

2. CORRECT. THIS IS DUE TO THE KAC STRAIGHT MOUNT HAVING A TOTAL BASE WIDTH OF 1 3/8" LESS THAN THE ARMS.

3. CORRECT. THE ARMS IS WITHIN A FEW HUNDREDTHS.

4. THE RING SUPPLIED WITH OLDER AIMPOINTS IS A SAD JOKE. I DO NOT KNOW THE HEIGHT OF THE RRA DEVICE, SO I CAN'T SAY WHAT WOULD OR WOULDN'T WORK. THERE'S NOTHING WITH A SQUARE SHOULDERED CROSSBOLT I KNOW OF THAT WOULD BE CLOSE TO THE CORRECT HEIGHT.

5. THE KAC THUMB NUT IS OPTIONAL. ITS POINTY ENDS HAVE NO FUNCTION I HAVE BEEN MADE AWARE OF.

6. FEEL FREE TO TRANFER THE FUNDS VIA WHATEVER MEANS IS MORE CONVENIENT FOR YOU. LIKE I SAID, WE APPRECIATE YOUR BUSINESS. I HOPE THIS COMMENTARY HELPED.

TATE,

THE AIMPOINT LOW PROFILE EXTRA WIDE RING MAY NOT HAVE A SQUARE SHOULDERED CROSSBAR, BUT IT IS A NICE UNIT FOR ONLY $24. IT ELEVATES THE AXIS OF THE AIMPOINT BY 0.84". SUBTRACT THAT FROM THE IDEAL HEIGHT OF THE AIMPOINT AXIS ABOVE THE FLAT TOP, 1.57", AND YOU GET 0.73".

SO, IF YOUR RRA RAIL IS THIS HEIGHT OR VERY CLOSE, YOU SHOULD BE GOOD TO GO. IF NOT, WELL THEN, THERE ARE SEVERAL SATISFACTORY MOUNTS AND BACK UP IRON SIGHTS TO CHOOSE FROM.

ACCURATE FIRE OUT TO 100 YARDS? WHAT IS "ACCURATE" FIRE? I HAVE TO ADMIT THAT I HAVE NEVER TRIED SHOOTING WITHOUT MY DOT THAT FAR. GIVEN THE DISTANCE AND THE LIKELIHOOD OF SOME MEANS OF COVER, I THINK I WOULD JUST FLIP UP MY BACK UP IRON SIGHT. AND AIM.

NOW, RUNNING THROUGH THE KILL HOUSE WITH TARGETS AT CLOSE RANGE, I WILL ADMIT TO SOMETIMES NOT USING THE AIMPOINT DOT AT ALL OTHER THAN FOR SNOT LOCKER SHOTS DESTINED TO SEVERE THE MEDULLA OBLONGATA OR SHOTS WITH HOSTAGE TARGETS. CALL IT POINT SHOOTING. I LIKE TO THINK OF IT AS MUSCLE MEMORY.

WITH SIMUNITIONS, THOUGH, THE SIMUNITIONS HELMET PREVENTS ME FROM GETTING ON THE GUN LIKE I NORMALLY DO, SO USING THE AIMPOINT DOT BECOMES ABSOLUTELY CRUCIAL. IN OTHER WORDS, I CANNOT POINT SHOOT WITHOUT A PROPER CHEEK WELD.

BESIDES, USING THE DOT I CAN MORE CAREFULLY SELECT A PINK TENDER PORTION OF MY TARGET TO SHOOT, IF EXPOSED, TO LET THEM KNOW THEY'VE BEEN HIT.

BUT, GIVEN THE FACT THAT I AM USUALLY OUTNUMBERED AND SURROUNDED IN MY ROLE AS ADVERSARY, AND THEY ARE ALL SHOOTING AT MY BACON, AS WELL, MY LIFE AS 'BAD GUY" IS USUALLY VERY, VERY SHORT.
