Question: Can I use any standard brush with this kit or do I need to purchase only Otis brushes?
Document: Unless I should by some exotic or new calibre, which to update what I have, we are talking about the purchase of an additional brush! Big deal!! I have found all my Otis kits well thought out and supplied for the price. The optional field kits are a nice perk and the extra brushes, pics ect. you think you may not use, I have found very handy in the field for many uses not just for guns. Kind of complements your survival kits uses.
Trying to figure out which cable works with which brush/slotted tip is not intuitive (a color coding system would be vastly more helpful). Albeit it's nice having the flexibility of cables/brushes/slotted tip to fit nearly every gun, it's just not a very straightforward thing to actually use them routinely. Additionally, getting a good grip on the cables to pull them through various barrels is difficult so it would've been nice if Otis had included a sufficiently sized and ergonomically appropriate handle to attach to all the cables.
Also, the kit contains NO mops at all for any caliber. Personally, I do not use mops to clean my firearms but, the mops for ANY caliber that you need are easily found and purchased and can be added to the kit. Because there were SO many items included with this kit... I decided to purchase a cheap plastic tackle box (about $7.00) and transfer all of the contents into that box.
This in itself I think is a major advantage to the Otis kit, nothing makes cleaning a weapon more easy then having everything you need neatly organized at your disposal. Just this morning I cleaned a .45 pistol, a 12 gauge pump shotgun, and a AR-15 all without having to get up and look for this or that tool making my cleaning times way faster.The qaulity of the brushes, patches, cables are very good.
Everything in the kit works great once you learn how to work the patches, but the case seems like an after thought, Like it was all thrown in a padded bag at the last minute. I plan to purchase a high quality hard case so I can add things like my large bottle of CLP, extra AP brushes, and stiff cleaning rods ect. Everything is clearly marked and I also like the removable tactical kit.
In the Otis, the patch for the 44 goes through with only light pressure, even when you use the biggest jag and pinch the longest part of the patch. I don't know what their special solvent is, but you can sit there running patches and the brush through all day, and every time after you run the brush, the next patch will come out with black on it, completely unlike their demonstrations where the patches come out completely white with minimal effort.
That's all solved by the Otis Elite - it has just about everything!Sure, there are some things I don't need right this minute, like a 28 gauge shotgun brush, but if and when I do need it, I have it.
I haven't used this yet on all the guns that I have but from the guns I have tried it on it seems to work well. It appears to cover most everything. The small .22 brush is handy for use on the Ruger Mk. III when you simply want to do a quick cleaning without taking the gun apart. I suppose it's obvious, but it doesn't work with traditional muzzle loaders unless you can remove the breech plug. So you will still need the rods for them.
I love the otis elite cleaning kit, I use it for my ar-15, 9mm, sks, and shot gun. It comes with anything and everything you would ever need to clean a gun. My only problem with the kit is the gun punch bent almost in half trying to take a plug out of the ar-15 new gun mind you. Other then that it has worked perfect and have used it around 15 to 20 times to far. P.S.
Very complete kit....would recommend this to anybody who has multiple caiber firearms and is planning to purchase more. Kudos to Otis
