Daniel Defense M4 Otis Cleaning Kit

Product Description

The Daniel Defense M4 Otis Cleaning Kit is a soft-pack cleaning kit built by Otis for AR-15-style firearms chambered in 5.56 or .223, combining a Ripcord pull-through bore cleaner, a solid rod set, a bronze bore brush and the B.O.N.E. Tool for the bolt carrier group in one case.

Field cleaning usually fails for a mundane reason: the good kit is on the bench at home and the range bag holds three patches and a frayed bore snake. This kit is sized to live in the bag, and the Ripcord makes a breech-to-muzzle pass in one pull without gravity feed, so a rifle that just ran a few hundred rounds gets wiped out with no rod, jag or solvent tray on the tailgate.

The other half covers the part most shooters neglect. The B.O.N.E. Tool scrapes carbon off the bolt carrier assembly, and its 8-32 threaded hole lets it double as a T-handle when fouling is baked on. A chamber brush and a double-end all-purpose brush reach the chamber and the locking lug recesses.

Frequently Asked Questions

Q: Will this kit clean a .223 Remington rifle as well as a 5.56 NATO one?

A: Yes. The kit is specified for AR-15-style firearms chambered in 5.56 or .223, so one kit covers both if you shoot them from the same upper. For a different bore size, such as 300 Blackout or a .308-based rifle, call 817-393-4000 first.

Q: What is the Ripcord and why use a pull-through instead of a rod?

A: The Ripcord is a pull-through bore cleaner that makes one breech-to-muzzle pass and cleans without gravity feed, so it works on a rifle standing in a rack or lying on a tailgate. The solid rod set in the same case handles a real bore scrub later.

Q: What does the B.O.N.E. Tool do?

A: It strips carbon and fouling off the bolt carrier assembly, which is where a neglected AR starts malfunctioning. An 8-32 threaded hole lets it run as a T-handle for leverage on baked-on carbon. With the chamber brush it covers the two areas behind most short-stroking.

Q: How hot can the Ripcord get before it is damaged?

A: Its braided Nomex surface will withstand heat up to 700 degrees, so pulling it through a bore still hot from a string of fire will not ruin it. That matters at a carbine class. Still let a hot barrel settle before scrubbing with a rod and a tight patch.

Q: Is lubricant part of the kit or do I supply my own?

A: A 0.5 oz bottle of Shooter’s Choice FP-10 Lubricant Elite CLP is in the kit, enough to clean, lubricate and protect the working parts for a good number of sessions. Most shooters keep a larger bottle at home and leave this one in the range bag.

Q: Does everything pack back into one case?

A: Yes – all items pack neatly inside a soft pack case, which makes this a range-bag kit rather than a bench kit. Rods, brushes, Ripcord, B.O.N.E. Tool, cloth, lubricant and booklet stow together. Call 817-393-4000 if you want the case measured against a bag insert.
