Barrel insert K11Barrel insert K11 aka . 45cal It simply inserts into the barrel and is then tightened by an expanding collet. The collet in the picture is anodized aluminum, but the current version is brass. Works well for said calibers when it is impossible or inconvenient to mount your SCATT optical sensor on the barrel or gas cylinder via a regular mounting system.

I gave this product to my sister for Christmas 2025 and it has already quit working. It will do the reverse but not extract. So disappointed!
