Thanks for the heads up guys!
Ok, these are good as long as they are the "Numbered" size drills. Just to be sure we are on the same page and for some of the other guys reading this thread... There are Metric drills and SAE drills. In SAE, there are three size ranges, there are Fractional Drills, which are of course measured in Fractions. Then there are Letter Drills, as in "A" through "Z" and they have a corresponding decimal size relating to them. And then there are the Numbered Drills, that also have a Decimal Designation for each and are stepped rather closely to each other, These are the Drills we are most interested in and we want to buy them in a set, sometimes called a Drill Index. The reason we want a complete index, is because we don't know what size we need, but in the "Numbered" Drill Index, there WILL be one, that is the right one. It is our task to find it, make the system work properly and assuring the timing, that recoil is manageable, and isn't ripping off the rims. For now, I only want you to digest, that we can do this, and then we'll get into specifics, and after you've learned them, you'll teach these guys what you learned, and be able to help someone yourself, because you've now received super knowledge, on the mysteries of the M16 system, and will understand what others are trying to figure out..t
