Description
Anyone who has tried to run a rod through an AR-15 bore while the receiver keeps swinging shut knows the frustration. The Sinclair AR-15 Cleaning Link fixes that annoyance by separating the upper and lower assemblies and locking them in an open position, so you get clean, unobstructed access to the breech, chamber, and bolt carrier area. It uses the rear takedown pin and rear pin hole, so there's nothing extra to clamp or attach. Pop it in and you're ready to work.
What the Sinclair Cleaning Link Does at the Bench
Instead of propping your rifle against something or fighting the receiver closing on your fingers, this link holds everything steady while you push a rod straight through from the breech end. That matters because cleaning from the muzzle risks wearing the crown, and a proper bore guide plus a stable open action lets you clean the right way. Pair it with a receiver or magwell vise block and the whole job gets a lot less fiddly.
Built From Delrin and Stainless Steel
The link is made of Delrin and stainless steel, which means it's virtually impervious to the solvents and cleaners you'll be splashing around. That combination keeps it from degrading over time the way cheaper plastic tools tend to, so it holds up through years of regular cleaning sessions. It's small, light, and easy to toss in a range bag or cleaning kit without taking up real estate.
Why It Earns a Spot in Your Kit
Sinclair International has a long-standing reputation for precision gunsmithing tools, and this little piece reflects that. It installs in seconds, does one job, and does it well. Folks who pick one up tend to say the same thing: they don't know how they cleaned their AR before it. If you run an AR-15 and want cleaning to be quicker and cleaner, this is one of those small tools that punches well above its size.

Frequently Asked Questions
How does the Sinclair AR-15 Cleaning Link attach to my rifle?
It uses the rear takedown pin and the rear pin hole, so there's no clamping or extra hardware needed. You separate the upper and lower, install the link, and it holds them securely in an open position. The whole thing takes just a few seconds.
Why do I want the action held open to clean an AR-15?
Holding the receiver open gives you clean, unobstructed access to the breech, chamber, and bolt carrier area. It also lets you push a cleaning rod through from the breech end rather than the muzzle, which protects the crown. Without a tool like this, the receiver tends to swing shut mid-job.
What is the cleaning link made of, and will solvents hurt it?
It's built from Delrin and stainless steel, a combination that's virtually impervious to the solvents and cleaners you use during maintenance. That means it won't break down or get gummy over time. It's made to hold up through years of regular cleaning.
Do I need anything else to use the cleaning link effectively?
The link itself does the job of holding the action open, but many people pair it with a receiver or magwell vise block to keep the rifle steady on the bench. A quality bore guide is also worth having for proper breech-end cleaning. Together they make the whole process much smoother.
