Brownells USA .223 Throat erosion ga 12/12/2013

This is a high quality product and performs as advertised, but not as easy to use or useful I first thought. It requires a lot of additional firearm knowledge to be a productive tool.

Primarily these comments are on erosion gauges in general, not this individual product. First you have to keep detailed records for a long time and you have to be firing a lot of rounds. You have to develop a technique of reading the gauge that is exactly the same each time. The depth reading you record can vary with the position of your head. Additionally the gauge doesn't really give you a failure point but rather a relative change over time. So you have to record your first reading then compare subsequent readings to get the relative change in wear. Since there really isn't any "failure" point, you just see slowly deteriorating accuracy. So unless you compare accuracy against throat erosion, then you don't really know what an individual reading means.

Also it's an odd shape, I thought it would fold or disassemble to fit in a smaller slot in my tool box.

That said, anybody who's serious about quality firearms, precision shooting and shoots a lot (it's going to take 1000's of rounds to see a difference), then it would seem to be a pretty essential tool.
