Hi all,
With the popularity of the AR platform these days, I came up with an idea (quite by accident) for a bore-guide for cleaning the barrels of my rifles.
My original idea was to modify a standard AR upper receiver block just so that it could be used to hold a dedicated .22LR upper assembly in a vice while I was building it. Because the .22LR barrel sits farther back in the upper receiver it prevents the installation of the standard receiver block. So I milled out the necessary sections of material from the Delrin block to clear the breech end of the barrel.

As I was doing that my mind turned to designing and making a separate bore-guide for cleaning the barrel as well. After checking the fit of the receiver block, and staring at it for a few minutes - it hit me. Drill a hole through it dummy!
With the block in place, and a guide hole drilled though it end to end - it makes a perfect accessory for holding an upper receiver for maintenance and now, for guiding a cleaning rod though the bore from the breach for cleaning the barrel. All in one tool.

Hopefully someone else will find it as useful as I do.
For what it's worth...
