You absolutely cannot damage your expensive match grade barrel with Swabits.
Metal cleaning rods are obsolete and the damage they can inflict.

.177 swabs are a great addition to the air rifle kit. Convenient and efficient. Super easy to use. Swabs rifle bore with little effort. Like the re-usability. I use a Sharpie to mark the end of the swabs, 1,2,3.

Could not find an all nylon jag to clean my .204. I don't use metallic bristle brushes or jags that have metal threads to clean the bore. I use a foam bore cleaner that is left in barrel over night and the swab-its .177
pull through gets the job done with just a few passes. And no metal to scratch the bore.

Make bore cleaning fast and easy.

I recently bought the swab-its for .177 and .22 caliber air guns. The BEST I have ever tried. Previously I have been using another pull through cleaner but didn't like because of the brass bristles (air guns tend to have soft barrels) and I was concerned about this. No more worries, just clean barrels. Thanks for a GREAT product, I will be buying more!!
