Dewey .20 Cal. 5-40 Thread Male Jag Review

The Dewey .20 Cal. 5-40 Thread Male Jag Made a Bold First Impression

The world of firearms maintenance often feels like a compromise between effectiveness and potential damage. Finding the right tools to properly clean your firearm without risking scratches or unnecessary wear is a constant challenge. That’s why the Dewey .20 Cal. 5-40 Thread Male Jag caught my attention – the promise of a non-reactive, bore-friendly cleaning solution at a surprisingly affordable price.

My need stemmed from consistent use of a .22 LR target rifle. Copper fouling, even in smaller calibers, can significantly impact accuracy over time. I’ve tried various brass jags in the past, and while they work, the blue-green staining from ammonia-based solvents always made me second-guess the cleaning process, unsure if I was chasing a ghost or genuinely removing fouling. The Dewey .20 Cal. 5-40 Thread Male Jag offered a potential solution to this problem.

Upon receiving the jag, I was immediately impressed by its simplicity. The machined aluminum construction felt solid, and the threads were clean and precisely cut. The weight was reassuringly light, hinting at the promised non-reactive properties. It’s a small piece, but the build quality was evident even at this price point.

I considered other jags, including some with bronze brushes and solvent ports. However, the Dewey jag’s claim of eliminating false positives from ammonia-based solvents was the deciding factor. The promise of a cleaner, more accurate assessment of bore condition swayed me. My initial impression was cautiously optimistic; the design seemed practical, and the material choice addressed a specific concern I had.

Real-World Testing: Putting Dewey .20 Cal. 5-40 Thread Male Jag to the Test

First Use Experience

My first test of the Dewey .20 Cal. 5-40 Thread Male Jag took place at my home cleaning bench, following a day of shooting my .22 LR rifle at an outdoor range. The weather had been dry and dusty, so I anticipated a decent amount of fouling. I used a popular ammonia-based bore solvent, carefully following the manufacturer’s instructions.

The jag threaded easily onto my existing cleaning rod, which thankfully also used a 5-40 thread. Pushing the patch through the bore felt smooth and consistent, with no excessive resistance. The most striking difference was the absence of the usual blue-green staining on the patch. This immediately instilled confidence that I was seeing true copper removal, rather than a chemical reaction with the jag itself.

There were no immediate issues. The jag held the patch securely, and the cleaning process felt more precise and controlled than with some of my older brass jags. It was a simple task made more satisfying by the clear feedback.

Extended Use & Reliability

After several weeks of regular use, the Dewey .20 Cal. 5-40 Thread Male Jag has proven to be a reliable tool. I clean my .22 rifle after every range session, so it sees consistent use. The jag shows no signs of wear and tear.

The aluminum has held up well to repeated solvent exposure, and the threads remain sharp and functional. Cleaning is straightforward; a quick wipe with a clean cloth is usually sufficient. Compared to my previous experiences with brass jags, the Dewey jag requires less aggressive cleaning to remove residue.

It definitely outperforms brass jags in terms of providing a clear and accurate indication of copper fouling. This allows for more efficient cleaning and prevents over-cleaning, which can be just as detrimental to barrel life as under-cleaning.

• The jag is constructed from machined aluminum. This material choice eliminates the risk of chemical reactions with ammonia-based solvents, preventing false positives when assessing copper fouling.
• Weighing practically nothing, its light weight prevents unnecessary stress on the cleaning rod and the bore. This is especially important for preventing damage to the crown.

Performance & Functionality

The Dewey .20 Cal. 5-40 Thread Male Jag performs its primary function of securing a cleaning patch and pushing it through the bore exceptionally well. The fit is snug, preventing the patch from bunching up or slipping off during cleaning.

Its strength lies in its ability to provide a clear and accurate indication of copper fouling. The aluminum construction eliminates the blue-green staining associated with brass jags, allowing you to truly see the amount of copper being removed. One weakness, if it can be called that, is that aluminum is a softer metal. It is important not to over-tighten the jag onto the cleaning rod to prevent stripping of the threads.

It exceeds expectations in terms of providing a hassle-free and accurate cleaning experience. It addresses a specific problem I had with brass jags and delivers on its promise of eliminating false positives.

Design & Ergonomics

The design of the Dewey .20 Cal. 5-40 Thread Male Jag is simple but effective. The machined aluminum construction feels durable, and the lightweight design prevents unnecessary stress on the cleaning rod.

The single-point tip is well-designed for securing cleaning patches of various thicknesses. There is virtually no learning curve. It’s a straightforward tool that anyone familiar with firearm cleaning can use immediately.

Durability & Maintenance

Given its aluminum construction, the Dewey .20 Cal. 5-40 Thread Male Jag should last a long time with proper care. Aluminum is resistant to corrosion, so it shouldn’t degrade with repeated solvent exposure.

Maintenance is minimal; simply wipe it clean after each use. Avoid using abrasive cleaners, as they could scratch the aluminum surface.

Accessories and Customization Options

The Dewey .20 Cal. 5-40 Thread Male Jag itself doesn’t come with any accessories. Its primary function is to interface with a cleaning rod and cleaning patches.

There are no customization options for the jag itself. Its simplicity is part of its appeal. It is compatible with any cleaning rod that utilizes a 5-40 female thread.
