Modern Spartan Systems Review: Green Gun Lube, Cleaners, and Suppressor Shield Tested
Modern Spartan Systems caught my attention because I take firearm lubrication seriously. A good lubricant is not just about making a gun feel slick. It is the heart and soul of keeping a firearm running, protected, corrosion-resistant, and consistent. After testing Modern Spartan Systems products, I came away impressed for a lot of reasons, including several I did not expect.

Modern Spartan Systems is built around a green, safer lubricant technology. Their product line reaches beyond firearms into areas like machine cutting oil, engine oil additives, fishing reel care, and knife lubrication, but the focus here is their firearms lineup: Accuracy Oil, Carbon Destroyer, Carbon Destroyer Double X, Copper Lead Destroyer, Crystal Clear, Nothing Left Behind, Spartan Accuracy Grease, Suppressor Shield, and their shooter kits.
What I like right away is that this is not a giant catalog full of random products. They have a focused lineup, and from my testing, the products work extremely well.
The core technology is based around bonded lubrication. This is not a typical “slather it on and go” gun oil. With Modern Spartan Systems, the application process matters. The surface needs to be properly cleaned and prepped so the lubricant can bond to the metal. That is where the real benefit starts to show up.
The idea is pretty simple: reduce friction, fill microscopic pores and surface imperfections, and create less drag between moving parts. In the bore, that means less drag between the barrel and bullet. Logically, that can help tighten standard deviations from shot to shot, and in my testing, I saw about a 20% improvement in accuracy.
That does not make it magic. It makes sense mechanically. A smoother, better-treated surface can help improve consistency. In my before-and-after testing, I saw a rifle that had been shooting around one-inch groups move into the 0.8 to 0.75-inch range. Your results may vary, but the logic is there, and my results backed it up.
The first product I would recommend trying is actually Crystal Clear, their lens cleaner. It may be the standout product in the whole lineup because almost everyone can use it. Shooters have scopes, red dots, range glasses, sunglasses, and binoculars. Even non-shooters have sunglasses or prescription glasses.
I used Crystal Clear on an old set of sunglasses I kept in my truck. I thought they were scratched up and worn out. After a couple of cleanings, they looked like new sunglasses. It also helped reduce fogging and left an anti-static layer that repels dust. That is a big deal for optics because some cleaners leave behind a static charge that actually attracts dust and makes lenses harder to keep clean.
If you test nothing else from Modern Spartan Systems, try Crystal Clear. It is inexpensive, useful, and easy to judge immediately.
The firearm cleaning products also performed well. Carbon Destroyer was one of the bigger surprises. I tested it with an ultrasonic cleaner and also with a simple Ziploc bag method. For a bolt carrier group, I let the parts soak, came back later, and saw black and brown carbon fouling pulled out of the parts. It worked shockingly well.
The key is dwell time. This is not always a quick spray-and-wipe process, especially the first time. The first deep clean and treatment takes longer because you are stripping the surface down and preparing it for the bonded lubricant. After that, follow-up cleanings become much faster.
For the bore, the process continues with Copper Lead Destroyer, then a final clean and dry before applying Accuracy Oil. Accuracy Oil is not a one-pass conventional oil treatment. It needs to be applied as a process because the carrier solution evaporates off and leaves the bonded lubricant behind. The treated surface may look fairly dry afterward, but that is part of how the product works.
For moving parts and higher-friction areas, Spartan Accuracy Grease makes sense. I used it on bolt carrier group contact points and also like the idea of using it lightly in a buffer tube. A little grease on the buffer spring can quiet down spring noise dramatically, which is basically the cheap version of buying one of those expensive quiet buffer springs.
The Suppressor Shield process is similar. You want the suppressor as clean as possible before treatment. For suppressors, I recommend an ultrasonic cleaner when possible because suppressors have a lot of internal complexity. A Ziploc bag soak can also work depending on the suppressor type.
I tested the suppressor process on a Heresy Design Resonator 22. After treatment, the suppressor ran cleaner. After 500 rounds, it looked like it had only seen a few hundred rounds, and the post-range cleaning process was much easier and faster than previous sessions.
For rimfire suppressors, that matters. Rimfire cans get filthy fast. Anything that makes suppressor cleanup easier is worth paying attention to.
Another major benefit is the safer, non-toxic positioning. I care about limiting exposure to harsh chemicals. A lot of gun cleaning products work, but they are nasty. If you clean guns in a basement, garage, shop, or small work area, reducing exposure to harsh industrial chemicals matters.
Modern Spartan Systems gives you a product line that is safer for the user, safe for the firearm, and still effective. That is the key point. The green technology would not matter much if the products did not work. In this case, they do.
Pricing is another strong point. These are not ridiculous $50 bottles of magic gun oil. The prices are fair, practical, and economical. Their kits also make sense because you get the products that work together: Accuracy Oil, Carbon Destroyer, Copper Lead Destroyer, Crystal Clear, and Spartan Accuracy Grease.
The shooter kit is probably the easiest way to get into the system because the products are designed to work together. Clean the surface, prep the metal, apply the bonded lubricant, and use grease where heavier staying power is needed.
What I appreciate most is that Modern Spartan Systems is not asking you to believe in fairy dust. The science is straightforward: reduce friction, prep the surface, bond the lubricant, and improve consistency. Based on my testing, the products performed exactly the way they were supposed to.
Modern Spartan Systems works. It is affordable, safer than many traditional chemical-heavy gun care products, and it delivered real performance in my testing. The Crystal Clear lens cleaner is an easy win, Carbon Destroyer cleaned better than expected, the Accuracy Oil showed measurable accuracy potential, and the Suppressor Shield made rimfire suppressor cleanup easier.
For shooters, suppressor owners, hunters, and anyone who takes firearm maintenance seriously, Modern Spartan Systems is worth a hard look.
