Most Helpful Positive Review Otis Star Chamber Cleaning Tool
Just what the AR doctor ordered. Cant beat how fast it arrived. Bought extra cleaning pads as well. The tool does exactly as claimed. Everything was in stock. Good prices. OpticsPlanet has always been positive transactions for me.
Most Helpful Negative Review Wanted it to Work Well
I really wanted this tool to work well to clean out the star chamber of my AR 15. It didn't. The tool extends but would collapse during use. The patches were minimally effective in cleaning. I can do a better job with Q-tips. Very disappointed. Poorly developed and made.

very helpful

by DannyWarren, Verified Owner from FL, United States Written on August 8, 2025
I haven't used the star pads it came with yet. I've been attaching bore tech reciever wiper set with the cheap patches and bore tech c4 cleaning liquid, bore tech chamber brushes, and chamber mop. It really only takes a few minutes to make that area of the barrel brand new depending on how long you let the solution sit.

Clever for the sake of clever... but this product is useless.

by JosephFix, from MI, United States Written on September 16, 2024
This product makes ZERO sense, except to separate AR users from their money, which is more than a cottage industry at this point. A "steel scraper" is not something you want to insert into the barrel extension... but don't worry if you already have because it doesn't fit snug enough to do anything. The soft pads are an interesting concept, but they just spin on the axis of the part that attaches it to the rod, so there's no resistance and no effect. A pack of replacement pads are priced similar to a box of 5.56 ammo. I use the handle to attach a dedicated chamber brush so I don't have to swap out attachments with my bore rod, other than that, this is just another 'miracle' gimmick that doesn't hold a candle to cotton swabs and a chamber mop.
Pros:
  • The handle is useful for other things
Cons:
  • Overpriced
  • Pads are way too expensive
  • A STEEL SCRAPER for my chamber? RU Serious?
  • Handle is delicate plastic
Would recommend: No

Otis Chamber Tool

by Capt. Mike, Verified Owner from FL, United States Written on January 4, 2018
I purchased this item based on the good experience I have had with other products by this company. This tool really doesn't do more than a patch on the end of a chamber brush. I tried it out on my well maintained AR and could not tell any additional cleaning advantage over the patch method described.
Pros:
  • none compared to patch and brush
Cons:
  • cost and replacement elements
Best Used for:
  • AR chambers
Would recommend: No

Star Chamber Cleaning Tool

by cko, Verified Owner from MO, United States Written on February 3, 2017
This tool works very well. The scrapper gets rid of carbon build up while the soft pad with a cleaning solution eliminates any residue. I recommend buying an additional package of pads. I used one for 3 cleanings. I like it.
Pros:
  • easy to use
Cons:
  • Plastic handle
Would recommend: Yes

Good tool for the job

by TS, from TN, United States Written on July 16, 2016
Another good product from Otis. Makes hard to clean AR star chamber easy. Scrape loose the junk then switch to the felt pads to remove the loose debris. So far it's the best tool I have found for this application.

Not perfect, but good

by Graham Baates, from OR, United States Written on April 13, 2016
Better than most other options for getting to that pesky star chamber. Until you switch to an AK it' a good option. Full review can be seen here: www.youtube.com/watch?v=b7Q2n6VkaWo&feature=gp-n-y&google_comment_id=z13mynp5nrmed3twn04cehhajnf0x114ioo0k

  • effective item
Cons:
  • feels flimsy
