Just sharing a hack devised to clean the K1 barrel quickly and easily. My friend and owner of a 25 confessed that he had never cleaned his barrel (3 years and many thousand shots!) because he didn’t want to get into any disassembly. We set about crafting a device to clean it that doesn’t require anything more than removing the moderator (if you have one fitted). It consists of a plastic tube within another tube - actually a radio control aircraft servo control rod, but any similar plastic tubes that just fit in the bore could be used. The inner tube has a fishing line loop glued into its end with epoxy, to hold the patch. Here is a shot of the smaller (yellow) tube holding the patch, inside the larger blue tube:
The yellow tube is retracted, pulling the patch into the blue tube ready for insertion into the muzzle:
Note that the blue tube has a black mark that represents the point to stop inserting it, measured to reach just shy of the magazine. The yellow tube tube has another mark that represents the point that it should be pushed into the blue tube to fully release the patch:
Then, as you guessed, the tubes are pulled out together, allowing the patch to clean. Rinse and repeat until you’re done, which in the case of this gun, was >20 patches!
Then clean the mag with a q-tip.
Just as easy as cleaning a conventional barrel, aside from the fact that it was so so dirty…
