Mops are especially excellent when using oil for bore lubrication because they create foaming action that helps in the lubrication process.
The second that this mop was inserted in the chamber it fell apart. The brass end wasn't crimped properly. Completely disappointed.
Original shipment and replacement failed. The crimp is not sufficient or the mop wire is twisted the wrong way but turing the mot clockwise in the bore immediately unscrews the threaded part from the mop.
Broke on first use ... either bad quality control or this item is junk. I put the mop into the chamber for the first time and turned, the mop came apart from the base. Horrible. I had to use pliers to get the mop out.
I really like this little mop. It does a great job of cleaning up the chamber after using a GI chamber brush. I’ve been running it dry to cleanup the remnants of carbon/gun oil after shooting and cleaning. It’s held up fine so far and I like it much better than the star shaped felt pads I have used before.
I literally put this in the chamber gave it a 1/4 turn and the head of the mop snapped off and all that was left on the cleaning rod was the brass screw.
Put this in your 5.56 cleaning kit. Or, if you're like me, put it into that huge tackle box that already contains ever brush, pick, and bore solvent you can buy.
The wire that screws into the threaded brass insert pulled free the first time I used it. I am not certain if I received a defective one or if this is a design flaw. To make matters worse, while screwing the wire back into the base, the threads snapped off inside my cleaning rod. Very disappointing.
They work great the first few times. Cleans the star chamber of the AR15 just fine.
