| Which Arms 22 ring height should I get for a Leupold 1.25-4x 20mm scope for mounting to a flat top or a carry handle mount? Thanks |

22H if you don more shooting standing. 22M if you do more shooting prone. 22L if you are putting it on a carry handle. www.csgunworks.com [email protected] Here’s some testimonials about CS GunWorks for AR15 Board Mike at CS Gunworks is... |

1.4" TO 1.5" SEEMS TO BE BEST FOR THE HEIGHT. UNLESS YOU'RE USING A LEUPOLD MR/T OR SIMILAR OPTIC WITH SHORT EYE RELIEF ON A FLAT TOP, THE ARMS RINGS WILL NOT PROVIDE YOU WITH SUFFICIENT EYE RELIEF, UNLESS YOU'RE A MIDGET. CHECK OUT THE EYE RELIEF SPECS ON YOUR SCOPE. YOU NEED:  THE LARUE TACTICAL SPR SCOPE MOUNT. WES GRANT M.S.T.N. |

There is no standard to how high or low to properly mount optics. Everybody's face is different, and what you may consider a good cheek weld, is not necessary what the next guy would feel comfortable with. Your gonna have to figure out what your face and eyes like by trial and error. I come from the school of thought of getting the optic down and as close to the barrel as possible, is a good thing. While Mark LaRue's SPR mount is very nice, and is the heat, and I own one still, it sits up too high for me while on a SIR system. Take a look at the ARMS #35, with or with out spacers. Mark also has the LT111 (Mrk11 Mod0) mount which mounts a little lower than the LT104 (SPR). Or you can go the basic ring route via LaRue's LT109's, ARMS 22's, Badger Ordnance, and or the new Nightforce Ultralights. Jim |

THERE ARE TWO POINTS I WOULD LIKE TO EMPHASIZE: 1. ON A FLAT TOP AR', FOR A SCOPE TO "FIT", IT MUST BE MOUNTED AT THE CORRECT HEIGHT ABOVE THE COMB, WITH THE CORRECT EYE RELIEF. 2. SOMETIMES "STANDARDS" FIT 95% OF USERS. SOMETIMES THEY ONLY FIT 50%. YOU HAVE TO BE THE JUDGE AS TO HOW YOUR MARK 1 MOD 0 PINK BODY INTERFACES WITH ANOTHER "SYSTEM". ACTUALLY, THERE IS A "STANDARD" AS TO HOW HIGH THE SIGHTING PLANE ON AN AR' SHOULD BE. IT WAS ESTABLISHED BACK IN THE LATE '50'S BY SOME GUY NAMED EUGENE STONER. IF YOU WANT TO MEASURE FOR YOURSELF HOW HIGH IT SHOULD BE ABOVE A FLAT TOP RECEIVER (SAME AS WITH A FIXED STOCK BUT THIS IS EASIER TO MEASURE), ALL YOU HAVE TO DO IS MEASURE HOW HIGH THE LARGE PEEP APERTURE IS ABOVE THE RECEIVER ITSELF: 1.4" THIS IS A SIMPLE FACT THAT CANNOT BE DISPUTED. PLEASE KEEP IN MIND THIS WAS DONE IN AN ERA, THE COLD WAR, WHERE WE PLANNED ON FIGHTING PRIMARILY A DEFENSIVE WAR, I.E., PRONED OUT, AGAINST OVERWHELMING NUMBERS OF COMMIES. THE CORRECT HEIGHT ABOVE THE FLAT TOP RECEIVER IS SLIGHTLY LOWER ON SR-25'S AND AR-10'S, DUE TO THE FACT THAT THERE IS MORE DROP TO THE COMB OF THE STOCK WITH THE DEEPER "BIG GUN" RECEIVER. THE CORRECT HEIGHT ABOVE THE COMB OF THE STOCK IS, YOU SEE, A CONSTANT. ALL THIS TRIVIA WAS NOT WASTED ON THAT GUY MARK LARUE AT LARUE TACTICAL. IN OFFENSIVE ACTION, WITH MORE SHOOTING STANDING, KNEELING, AND MOVING, THE SIGHTING PLANE NEEDS TO BE A TAD HIGHER. THAT IS WHY WE SEE THE FOLLOWING HEIGHTS IN THE LARUE PRODUCTS: SPR SCOPE MOUNT 30MM 1.50" MK 11 MOD 0 MOUNT 30MM 1.45" (LOWER MOUNT FOR TALLER RECEIVER, REMEMBER?) AIMPOINT CCO MOUNT 1.725" (FOR REALLY RUNNIN' & GUNNIN') OF THE SCOPE MOUNTS LISTED ABOVE, ONLY THE LARUE SPR SCOPE MOUNT AND THE ARMS #35 QD BASE WITH ARMS #35 TRACK LOCK RINGS OFFER THE CORRECT EYE RELIEF FOR THE SCOPE IN QUESTION. AS A SIDE NOTE, THE ARMS #35 QD BASE WITH LOW RINGS GIVES YOU 1.25" ABOVE THE RECEIVER. OK FOR SOME, BUT TOO LOW FOR ME. WITH THE MEDIUM RINGS (LOW RINGS WITH THEIR MEDIUM SPACER), YOU GET 1.55", IIRC. I WAS AN EARLY CHAMPION OF THE ARMS #35 SYSTEM DUE TO THE FACT IT OFFERED THESE FEATURES. HOWEVER, PLEASE BE AWARE THAT TOLERANCES DO INDEED "STACK". WITH THE ARMS #35, YOU MUST ASSEMBLE SPACER AND LOWER RING HALF TO THE #35 QD BASE VIA A SINGLE SCREW IN ABSOLUTE PERFECT ALIGNMENT WITH THE OTHER RING HALF IF YOU ARE NOT TO SCREW UP THE FINISH ON YOUR SCOPE AND POSSIBLY CRIMP IT. THE LOWER RING HALF NATURALLY WANTS TO ROTATE CLOCKWISE AS YOU TIGHTEN THE SCREW THAT GOES THROUGH IT AND THE SPACER INTO THE BASE. USING YOUR HIGH DOLLAR SCOPE AS AN ALIGNMENT FIXTURE IS NOT ADVISED. MY PARTNER PAUL E. DEVELOPED A TECHNIQUE WHERE HE USED A 30MM STEEL LAPPING BAR TO ACHIEVE THIS LEVEL OF ALIGNMENT WHILE TIGHTENING THIS SCREW. IT TOOK TWO SETS OF HANDS AND MULTIPLE ATTEMPTS TO ACHIEVE THE DESIRED RESULTS, BUT WAS DOABLE. I'LL AVOID GETTING INTO A "ARMS VS LARUE" THROW LEVER DEBATE. I WILL RELY ON MY PERSONAL EXPERIENCE WITH BOTH SYSTEMS, NOT THE HYPE OF OTHERS. I AM FIRMLY CONVINCED THAT THE LARUE SPR SCOPE MOUNT IS THE SINGLE BEST THING TO EVER HAPPEN TO FLAT TOP AR'S AND SCOPES. AND TO SHOOTERS. YES, I SELL LARUE STUFF. HOWEVER, I DO NOT PROMOTE IT BECAUSE I SELL IT. I SELL IT BECAUSE I BELIEVE IN IT. WES GRANT M.S.T.N. |
