Are you the type of man or woman who wants great shooting firearms along with unrivaled accuracy every time you pull the trigger? Fantastic! You are among most other shooters and hunters out there who are always looking for a way to optimize your firearms for a trip to the range, the next hunt, or when you have tickets for an exotic hunt in a foreign country. Or perhaps you’re an aspiring competition shooter looking to shoot your first 1000 meter target? Either way, you need the most out of your firearms to accomplish the task at hand. Today, I bring you a review of my experience with a new way to do so. A new way to optimize your tool of the trade and make the most of anything from your Kentucky Rifle to a 1911, M14, AR15, Surgeon, Gunwerks, or MOA Rifle. I bring you Accuracy Oil and Grease from Modern Spartan Systems. A simple, yet effective way to increase your accuracy through the application of proprietary lubricants that bond in a special way to the surfaces in a firearm.

Upon receiving my package from Modern Spartan Systems (only five days after placing it) I inspected it for damage or anything that may not be caused by our mail systems. It didn’t have any noticeable tears, deforms, or stress signs. The box was well-fitted to the product, ensuring the obvious associated with high quality packaging. Labeling was clear, and was not damaged in anyway whatsoever. As I opened the box I took out the Starter Kit, and immediately noticed that the product was easy to read and text was appropriately sized for the label. No cheap paper labels here, Spartan Modern Systems uses a foil label that was seemingly pressed onto the bottle by Hercules himself with adhesive equally strong. Upon inspection of the Spartan Starter Kit, one would swiftly recognize the strength of the plastic box it is packaged in. This isn’t a package you find wrapping a product from Walmart in the clearance aisle. The case latch was very strong and latches consistently as I opened and closed the box more than 50 times simply to test durability. Modern Spartan Systems wraps their products with very high quality packaging, a signal that the company wants high quality in every aspect of the customer experience.

I live and breathe firearms and the relationship between shooter and rifle. As a former Non-Commissioned Officer in the United States Army, a combat Vet, and a current NRA Instructor, I have been searching for a better lubricant for a long time. My search ended when I came into contact with Marcus Kahn at Modern Spartan Systems and used his company’s products. Not only did I find a better lubricant, I found a path to better accuracy where I least expected to find it.

Carbon Destroyer

The first thing I did was used a product by Modern Spartan Systems call “Carbon Destroyer” ($9.50 / 2 FL Oz.) on my 1943 Mosin-Nagant rifle to ensure all the Carbon was removed. This is a fantastic product that fundamentally changes the game when it comes to DI AR-15s or anything else that produces a lot of Carbon, but that’s for another time as the Carbon Destroyer is a great enough product to warrant its own review (with my AR rifles as well). The next step I took in accurizing my Mosin was to use another product called Copper/Lead Destroyer ($11.00 / 2 FL Oz.).

Copper/Lead Destroyer

Anyone who’s ever shot a Mosin-Nagant M1891/30 with surplus rounds (1970’s Bulgarian surplus) before knows those chambers and bores can get demolished with lead, as well as corrosive salts. The latter is usually irreversible damage over time and the former is so difficult to do most just buy a new rifle. Copper/Lead Destroyer was seemingly designed specifically for this type of environment, and does an exceptional job of removing Copper and Lead from the bore. It will remove the corrosive salts, it does a great job of after range cleanup, but will not be able to remove pitting that can happen with time from corrosive salts. I saw multiple pieces of debris removed by my bore after using it, and was surprised to say the least. I will say, this is a lengthy process, laborious, and can get boring. Have you ever been successful in removing all that Copper and/or Lead from your bore without paying a gunsmith? I thought not. That being said, it took considerable effort to do so, with many passes of a bore brush, and all well worth it in the end.

Accuracy Oil & Grease

The Accuracy Oil ($11.50 / 2 FL Oz.) and Accuracy Grease ($11.50 / .025 FL Oz. Jar) are two very important, and symbiotic components to shooters. I will get right into the good stuff for you shooters. I increased my accuracy so significantly on my 1929 Mosin-Nagant, I nearly halved my shot groups at 100, 200, and 300 meters on my best groups. Yes, you read that right, I cut my best shot groups in half at 100, 200, and 300 meters. For the more scientific types, I took my average MOA in a three shot grouping from an that of 2.5 MOA to 1.5 MOA (my best grouping) with an average of 1.8 MOA. Realistically, a decent Mosin from war years can achieve around a 2-3 MOA. Non-War years I have seen people achieve far better at 100 meters at about 1 MOA and sometimes sub-MOA with bipod, scope, crowned barrel, bedded stock, or anything else that may be considered “sporterizing” your Mosin and match grade ammo. I did my testing at various distances to ensure I wasn’t just lucky, as well as to provide my data different variables to work with. Now, I did not bed my stock, or put an 11 Degree Target Crown in my barrel, or even shoot with a scope, let alone use anything except surplus Bulgarian rounds weighing in at 147 grains each. My testing was done completely stock from 1929 with iron sights, the same way a Red Army soldier would have been firing this in the 1940’s.

At this point, you may think to yourself, “How the hell does oil and grease improve my accuracy?” It’s a scientific method that is fundamentally different than traditional lubricants. This is not an oil like you’re used to with Frog Lube, CLP, Militec, or anything else. Those do reduce friction but they are inferior to how Modern Spartan Systems products work. What Marcus and crew achieved is penetration of the metal surfaces within your firearm with molecule sized lubricants. Theses lubricants bond with the subsurface of the barrel, throat, etc. and essentially restructure the metal. While it doesn’t literally restructure it, it effectively does so by filling in the natural pores of the material and creating a super slick surface that is bonded in a way that oil can never achieve. While this is a much better way to lubricate your firearm, one does need to be aware that this is happening on a microscopic level, and only semi-permanent. If you’re used to caking your bolt and barrel with CLP, you have to wrap your mind around the fact that this works far differently than CLP or other oils. You may inhibit accuracy gains by adding too much. As for being semi-permanent, no lubricant will not ever wear away from the extreme environments found inside a firearms barrel. While this does reduce friction by a claimed 80-90%, and does last much longer, you will have to reapply from time to time. This isn’t a “fire-and-forget” kind of thing that you don’t ever have to worry about.


As a former Soldier and current NRA Instructor, I am telling you that this is one of the easiest ways to improve your overall accuracy. Trying to bang the gong at 500 meters more than 2 of 5 shots on your old Mosin-Nagant from 1917? I’ll tell you first hand that this product is one way to do so, though it won’t be every shot, you’ll make your rifle capable of doing so more often. Now, I will say that every trigger pull is a harmonious relationship between man (or woman) and rifle. That no matter what happens the shooter has to have a basic skill developed to shoot a firearm along with considerable safety training. This is not a “Cure All” that you can throw on your rifle and start shooting pebbles at 1250 meters when you can’t hit a boulder that’s 50 feet away prior to application. But it is a brand new method for optimizing your firearms and making the most out of them with a proprietary blend and application method. One that bonds with your firearm and makes the most of it.

Accuracy Grease

What I will say is there is no replacement for training. Most shooters cannot outperform the rifles they are shooting with, yet are always looking for ways to improve their shots without improving themselves. While this may or may not help in that arena, it will not be very significant if you suck at shooting. “Practice perfectly what you suck at” is something I say to people all the time. I encourage all to take a class in the category of firearms you’re looking to improve on and learn from a professional. They will give you the basic building blocks of how to improve yourself. Learn from a professional, find the best your firearm can perform, then put on the products from Modern Spartan Systems to make the best of your shooting experience. Accuracy Oil and Accuracy Grease, a profound product from a great company, which will help all levels of shooters. And I promise just as much as Marcus Kahn, their CEO, guarantees that this will help improve accuracy, especially for those who are already well trained in the fundamentals of shooting. Pricing was very much lower than I expected for what these products do. I had a bit of skepticism when I first saw the prices compared to the claimed capabilities but after testing I became a believer.
