ok....so I emailed Talley to see how much higher their high rings are over the medium ones I have. They said .10". How much is that??? ok there's 2.54 cms in an inch. 1/10 of that is .25 cms. But how much taller is the high over the med in 1/16s of an inch (something i can use) to determine the height difference???---DrAsus

OK; I think you are confused as to the difference between Metric and Standard (English or whatever you want to call it). Our inch system was broken up into sixteenths of an inch or even thirty seconds of an inch which results in the 1/16, 1/8, 1/4 etc. You can also break the inch into tenths or hundredths which results in measurements like .10, .50, .75 etc. The measurement of .10 is ten one hundredths of an inch. Now that you are really confused the main thing to get you close to something you understand is that 1/8 of an inch is .125 in hundredths; so the .10 is just a shade less than 1/8 inch. All of the above is English measurement; Metric measurement is another whole bag of stuff I doubt you really care about but it is based on the Meter not inches or yards. One Meter is close to a yard. Hope this helps and does not make things worse. To get you even closer 7/64 comes out to .109375.

thanks......thats what I needed to know---that it's almost 1/8" higher-----DrAsus

If you were to go to a Drafting store or drafting supply house, you would be able to get a thre sidded rule, It would have a side that is broken down in 10ths. If you have a caliper that should help you see how much this is also.

.10 or.100" = 1/10" = 2.54 mm

.125 = 1/8" = 3.175 MM

I love your title, metric/standard help , I hear you load and clear!

Screwbolt----thanks for the drafting idea. I understand the difference between mm and cm etc etc. However I think it is poor customer service to give a customer the dimentions they seek in a format that is not widely used. All i wanted to know (from Talley) was how much higher the "HIGH" mount was compared to the "MEDIUM" one I currently have. Why they responded with "1/10"" I do not know. All I have are standard/english (whatever you want to call them) tape measures which have sixteenths (1/16). Why Talley couldn't say that the HIGH mount was almost 1/8" taller I do not know. ---DrAsus

Manufacturers typicaly deal in thousandths of an inch. That's the way tolerances of parts are specified. Hypothetically, apart that is supposed to be an inch long may be 1.000 +/- .005 and still pass Q/C. Of course, tolerances may be tighter or looser depending upon the part.

I'd be more surprised if they answered your question with, "almost and eighth of an inch". If you asked a gun MFR what your bore size is, do you think they'd say it's a half inch? They'd probably say it's .501 (or whatever) and they probably wouldn't tell you what the tolerance is.

DrAsus - .10" . Well, 3/32" = .093" So that should be as close as you get to .10"
