This is the kit you need for your ,22 and .25 cal Air rifle. Comes with a set of patches and felts. Pair this with some ballistol for wet patches then follow up with dry patches to get it all cleaned up. Use the line without the plastic bead for .22.
Also works on .177 with 7/8 patches. You may need to off center the patch slightly if your 177 has a tight bore.
