Review: Excellent tools! - Excellent hand tools. These are a must have if you are an at home gunsmith. Excellent for fitting 1911 safeties, or doing work on AR triggers. Lots of applications you could use these for. Otis is a known company in the firearms world, and they make a quality product. This set of files is no exception.
Review: These are stock Otis patches - If your going to use otis cleaning products then use only otis products with the cleaning systems because they are made to work together perfectly, once you figure out how to correctly attach the patches to the slotted tips your golden because they give 360 degree coverage every pass through the bore and each patch can be used up to six separate passes per patch by using each slot once and then turn the patch over and use the same three slots in the patch again, so you can really maximize your use of each patch which actually saves you money this way. There isn't any bad points I can think of about these patches other then the price is a little high at almost $10.00 per 100 patches but if you use each patch 6 times it's almost like your getting 600 patches worth of use.... Anyway these are a must have item when your initial stock that came with your cleaning kit runs out and I have a fairly large gun collection and I'm always cleaning one or another so it helps to be able to use each patch more then once BC

## Questions & Answers

**Q: Could I use these to clean my 30-30 and 30-.06?**
A: These patches are not designed for 30 cal use as they are made to use only up to 25 cal. I would opt for larger ones for the calibers you desire to properly clean.

**Q: This wont fit a 12 gauge will it? have rifle and shotgun cleaning kit. should i get "all caliber" patches?**
A: .223 patches are much smaller than what is needed for a 12 gauge. My recommendation is to buy patches for specific calibers or a family; e.g., .30 cal for 7.62, 300, 308, etc. .45s & .38 (.357 et al). Or you could buy large patches & medium patches in bulk and cut them down as needed. Personally, I do not really like the patches which are available in todays market, which seem to be some type of synthetic. I would like to use all cotton, preferably a flannel. Todays patches seem to require a lot of product to achieve a clean barrel.

**Q: The video demonstration hookup seemed only for "pulling" the patch through the cylinder, no?**
A: Correct, it is designed to be pulled through the barrel in the same direction that the projectile travels.

**Q: Are these 1 1/4" round patches?**
A: These patches are 2 inches in diameter.
