I'm looking at spr mounts for a Leup. 4.5x14 40mm vari-xiii and a trij tr21. I'm wondering what the scope height with the spr mounts are for these 1" tubes. (height either to base of tube, or to centerline of scope tube.) |

THOSE ARE THE HEIGHTS WITH 30MM RINGS. YOU MUST NOT HAVE TOLD THEM YOU WERE USING A 1" SCOPE. THE BASE IS THE SAME WITH BOTH THE LT104-1" AND LT104-30MM. THE RING SIZE MAKES THE SCOPE AXIS HEIGHT A LITTLE DIFFERENT. WITH 1" RINGS, YOUR SCOPE IN THE LT104 ENDS UP LOWER: 30MM MINUS ONE INCH EQUALS 0.18". 0.18" DIVIDED BY TWO EQUALS 0.09". 1.5" MINUS 0.09" EQUALS 1.41". THE AXIS OF YOUR SCOPE IN AN LT104 (OR THE LT139 - SAME DEAL) WITH 1" RINGS WILL BE 1.41". FOR COMPARISON'S SAKE, YOUR IRON SIGHTS ARE ALSO 1.41" ABOVE THE FLAT TOP. GOING SUBTLY HIGHER WORKS FINE, ESPECIALLY IF YOU HAVE A BIG MELON OF A HEAD LIKE ME. BUT, IT IS UNDESIRABLE TO GO LOWER. AN AWFUL LOT OF THOUGHTFUL ENGINEERING WENT INTO THE DESIGN OF THE LT104.

You know, I know everyone goes for the spr-e for the tr-21... but in looking at pics of scopes on guns, it almost looks like it's overkill for what i need. Compared to the 104, it's a lot of unsupported metal under the scope compared to the 104. Will a 104 cut it for an spr-e? Is it worth worrying about the unsupported metal of the spr-e? (yeah, I know this thing is built like a brick poop-house, but I figured I'd ask). |
WITH THE TR-21, YOU HAVE TO HAVE THE EXTENDED EYE RELIEF ONLY OFFERED BY THE SPR-E MOUNT. THERE IS NO ALTERNATIVE. WES GRANT MSTN.BIZ |
