These seem to be of poor quality. They will fit in the primer end of the cva breech but will not slide on the the discharge hole in the nipple. The problem is not really that they won't slide all the way through the breech plug, I don't believe any cleaners are that small...the real issue is that they leave alot of "fuzzies" behind that in turn have to be cleaned off. Ironic!!
Bottom Line No, I would not recommend this to a friend
Keep your hands clean while taking care of
your rifle. The stick applicator allows you to apply the Anti Seize Stick directly on the threads without getting it on your hands. Keep one handy for easy accessibility.
