when you have your rings aligned with a 1 inch dowel and you are ready to put your scope into them place a few drops of blue loctite on the bearing surfaces... this will help bed and hold the scope... the loctite will fill gaps in that tight of an environement and will fill voids that could hold moisture... you don't need much... just a few drops. if you ever want to remove the scope it is pretty easy since the blue loctite won't adhere readily or strongly to smooth flat surfaces. don't use a red or green (FOR SURE NOT GREEN) if you ever want to take it apart...

a torx is a 6 point star where-as an allen is a hexagon.. takes a torx bit to get proper drive and is a stronger design than an allen... sometimes you can get an allen in but if you are not ginger with it you;ll round it out pretty quickly...

make sure you draw each side of the top of the ring down evenly a bit at a time... and don't try to overtighten the small screws.. you'll twist the heads right off if not careful...

rings and bases are a small price compared to the gun and the optics... so buy quality pieces... generally you'll get what you pay for...

i've gone to Leupold QR bases and rings... since i seem to now have more guns than i have scopes at the moment... Leupold says that you can remove and reinstall and be within half a MOA at 100 yds in repeatability... i've found that they stay closer than that, least on the 700 i've been fiddling with all summer and fall... plus i have a few hundred rounds through this thing, fireforming and load development and they are holding strong...
