Rear Sight Alignment Tool For HK91/PTR91/HK33/C93/CETME C

thingiverse

This is a sight alignment tool for welding your HK drum sight to your HK roller-delay series receiver, or CETME C receiver. To use the tool you simply clamp it in place with the drum sight loosely placed on top of the receiver. Align the sight tool with the rear claw mounts, and check to see that you have ample space between the topmost rib of the receiver and the front portion of the drum sight mount (usually between 1-2mm). Then proceed to start welding! When welding, I recommend tacking the front portion of the sight base first, then moving to tack the sides into place. You can also use the tool to check alignment of the sight base after tacking. This is compatible with both the HK33/93 series receivers, as well as the HK91 style receivers. It also works with the CETME C receiver flats provided by RTG Parts. If you would like to buy a print, please visit: https://www.gunbroker.com/item/878439004
