get the spec (I KNOW its out there, if you can't find it, shoot me an IM with your email and I'll see if I can dig the pdf I've got up and email it to ya)
Check dimensions on drawing against your rail to see if they're within the +/- as noted in the spec. Good set of dial calipers should take care of most measurements for ya |

Ahh just found THIS:
http://www.biggerhammer.net/picatinny/ Question: if there is a minus behind the listed dimension, does that mean for that particular measurement there is only a minus tolerance allowed and not anything in the other direction? I'm obviously not experience at reading these types of documents so. For instance it looks like the width of the rail from edge to edge is listed as: .835-.005 So, that translates to a range of .830 to .835 right? |

a set of gages is the only way to really check it, are you just looking for the height?
Yes to your tolerance question. |

Rodger to the rescue!
 Mostly I wanted to check slot depth, slot width, and the width of the rail itself fore to aft. I would imagine the guages allow you to check the angles on the rail, or at least I'm guessing. |

You can do those with a mic but to check rail spacing (including the slop) the gages are the standard.

Tweak, just for reference purposes, since I doubt I'm gonna run across a set of gauges: can you describe what they look like and how they work? I would imagine I'm not the only one that is curious about this.
Thanks man! |

JLM,
I've never seen a set but IIRC how they were described to me they look like a negative set of the rail. The rail either fits or not, much like a thread NOGO gage. |
