SSK Firearms Nipple Percussion Cap Review

True Results from the SSK Firearms Nipple Percussion Cap

For enthusiasts of classic firearms, the ignition system is paramount, and a reliable nipple is the linchpin of percussion cap firearms. The SSK Firearms Nipple Percussion Cap aims to provide that critical component with enhanced durability and optimized function. As someone who has relied on period-correct and modern components alike across a decade of working with historical firearms and their modern counterparts, I was keen to see if this offering from SSK Firearms lived up to its robust specifications. My own vintage percussion revolvers had been showing signs of wear on their original nipples, leading to inconsistent ignition and a general sense of unease during live fire exercises. I needed a replacement that wouldn’t just fit, but would offer improved longevity and reliability over the original design. While I briefly considered sourcing NOS (New Old Stock) parts, the uncertainty of their condition and the lack of modern material advancements made me lean towards a manufactured solution. My initial impression upon unboxing was one of understated quality; the material felt substantial, and the machining was precise, hinting at a product designed for enduring performance.

Real-World Testing: Putting SSK Firearms Nipple Percussion Cap to the Test

First Use Experience

My testing grounds for this specific component were primarily my workshop bench and my dedicated, safely managed shooting area for black powder firearms. The initial installation onto a .36 caliber caplock pistol was straightforward, requiring only standard tools and a touch of oil on the threads as recommended. The SSK Firearms Nipple Percussion Cap threaded in smoothly, with no signs of cross-threading or excessive force needed. I tested its performance across a range of ambient temperatures, from a cool early spring morning to a warmer afternoon, and even exposed it to a light, controlled mist to simulate dew or humidity.

Ease of use was high; once installed, it functioned identically to a well-maintained original nipple, but with a noticeable improvement in primer seating and detonation consistency. There were no immediate issues or surprises, which in the world of firearms components, is often the highest compliment one can give. The concave face of the nipple seemed to effectively direct the flame from the percussion cap into the powder charge, and the optimized flame channel felt responsive.

Extended Use & Reliability

After several weeks of intermittent use, including multiple range sessions and bench testing, the nipple has held up exceptionally well. I’ve fired perhaps fifty to seventy rounds through the pistol equipped with this part, and there are no visible signs of degradation. The hardened tool steel appears to be living up to its claim of maximum life, showing no discernible wear on the cap seat or the threads.

Maintenance has been minimal; a quick wipe-down with a solvent-dampened cloth after firing and a light re-oiling of the threads before storage are all that’s required. This is consistent with the maintenance of other high-quality firearm components. Compared to the pitted and worn original nipples I’ve encountered or used, this SSK offering feels significantly more robust and reliable. It has certainly outperformed budget aftermarket nipples that sometimes exhibit softer metal and quicker wear.

Breaking Down the Features of SSK Firearms Nipple Percussion Cap

Specifications

The SSK Firearms Nipple Percussion Cap is designed for all No. 11 percussion cap ignition systems. It is meticulously machined from S7 impact-resistant tool steel, a material chosen for its exceptional toughness and ability to withstand repeated impacts. Furthermore, it is hardened to Rc54-56, a Rockwell hardness scale reading that indicates a very hard surface capable of resisting wear and deformation.

The nipple features an optimized flame channel intended to ensure a consistent and reliable ignition pathway for the powder charge. This design choice is crucial for preventing misfires and ensuring a crisp ignition every time the hammer falls. Additionally, a concave face is incorporated, which aids in redirecting combustion gasses. This feature helps to create a more efficient burn and can contribute to a more consistent shooting experience by managing the explosive forces involved. SSK Firearms also advises applying a drop of oil or a quality lithium or molybdenum disulfide grease to the nipple threads before installation to ensure a proper seal and prevent seizing.

Performance & Functionality

In terms of its primary function, the SSK Firearms Nipple Percussion Cap performs admirably. It consistently ignites percussion caps, providing a reliable spark that reliably sets off the black powder charge within the firearm. The optimized flame channel and concave face seem to work in concert to deliver a strong, directed flame to the powder.

Its strengths lie in its perceived durability and ignition consistency. I experienced very few, if any, hangfires or duds during testing, which is a significant improvement over some older or lower-quality components. The primary weakness, if one could call it that, is its specific application – it is designed for No. 11 caps, meaning it’s not a universal fit for all percussion systems. However, for its intended use, it meets and often exceeds expectations, especially considering its competitive price point.

Design & Ergonomics

The build quality of this nipple is immediately apparent. The use of S7 tool steel gives it a substantial feel, and the hardened surface promises longevity. The machining is precise, with clean threads and a well-formed cap seat.

Ergonomically, as a small firearm component, its design is inherently functional. The concave face is a subtle but smart touch, and the overall shape is designed for efficient gas flow and cap seating. There were no obvious grip points or tactile features, as it’s not meant to be handled extensively once installed. The design is practical, prioritizing function and durability over aesthetic flourishes.

Durability & Maintenance

Based on the material and hardening specifications, this nipple is built for durability. The S7 tool steel and Rc54-56 hardness suggest it should withstand significant use without significant wear. I anticipate it will last for many hundreds, if not thousands, of rounds before any performance degradation becomes noticeable.

Maintenance is as simple as one would expect for a firearm component: keep it clean and lightly lubricated. There are no complex parts to disassemble or special cleaning procedures required. The main point of care is ensuring that the threads remain clean and properly lubricated to prevent seizing and facilitate easy removal if needed in the future.

Accessories and Customization Options

The SSK Firearms Nipple Percussion Cap itself is a single component, and as such, it doesn’t come with a suite of accessories. Its primary purpose is to replace or upgrade an existing nipple on a percussion firearm. Therefore, the “accessories” are the percussion caps themselves (specifically No. 11 percussion caps) and the lubricant recommended for the threads, such as lithium or molybdenum disulfide grease.

While there are no direct customization options for the nipple itself, its compatibility with the No. 11 percussion cap system is its key feature. This ensures it integrates with a widely available standard, allowing users to continue using their preferred brand of caps.

Pros and Cons of SSK Firearms Nipple Percussion Cap

Who Should Buy SSK Firearms Nipple Percussion Cap?

This nipple is an excellent choice for owners of percussion firearms that utilize No. 11 percussion caps, such as many revolvers, pistols, and rifles. If you are experiencing inconsistent ignition, worn-out nipples, or simply want to upgrade to a more durable and reliable component, this is a solid option. It’s particularly well-suited for shooters who engage in historical reenactments, target shooting with black powder firearms, or enthusiasts who value the longevity and performance of their vintage or reproduction firearms.

Those who should probably skip this product are individuals with percussion firearms that require a different cap size (e.g., musket caps, No. 10 caps) or those seeking a nipple for a flintlock ignition system. While not strictly necessary, having a small tube of lithium or molybdenum disulfide grease on hand would be a wise complementary purchase to ensure the easiest and most reliable installation and future removal.
