Mfr Part: RG9172

The O-rings on your Sinclair bore guides, snouts for Sinclair All Purpose Rod Guides, Solvent Ports and Chamber Plugs should be replaced occasionally because solvents and use eventually wear them out. We use three sizes of O-rings only, so having some spares on hand is not expensive. The 222 and 223 family of guides and the 17 caliber guides do require the O-ring installation tool included in the O-ring kits. The two larger size O-rings can be installed fairly easily without the tool, though the kits include the tool for almost no additional charge over the 10 O-rings. All three O-ring sizes are available separately in 5-packs.

Brownells USA Impossible to install - even with tool 11/03/2017

The very first time I used the AR-15 rod guide, the o-ring failed. I ordered replacements. They are IMPOSSIBLE to install without breaking, even using the provided tool. Either I'm using the tool incorrectly (no directions were provided) or the rings are just too fragile. I've decided to just use the rod guide without the o-ring. I would not buy this again (and consequently not the AR-15 rod guide).



By the way, I've had the .308 rod guide for several years and it works great. The original o-ring provided with the rod is still in good working order. The .22 cal o-rings are just too fragile.
