I recently had a chance to work with the O.S.S. Suppressor system here in Texas. Let me first tell you a little about the company, and what these guys are all about.

O.S.S. (Operators Suppressors System)

O.S.S. develops and manufactures suppression technologies that are based on real world, wartime, and commercial demands. This company is operated and owned by former Special Operations and Law Enforcement members, with over a century of combat and special operations combat experience, most of which came post 9/11. With the amount of knowledge these guys have, they produce some of, if not the best, suppressors on the market today.

The Suppressor

With most suppressors, like the ones that I’ve used as a special operations sniper and assaulter, when the weapon is fired, I tend to get a ton of gasses in my eyes, nose, and mouth. The suppressor’s goal is to retain gas, and when the breech is open it flows back.

The gasses in the mouth and nose may not bother some shooters, but to have gasses pushed back into your eyes is a “No Go,” in my opinion. Having gasses in your eyes, whether in combat or on the range, will not only affect your accuracy, but your situational awareness as well when shots on target may matter the most. With the O.S.S. suppressor, you won’t have to worry about this problem.

Ever have problems with shift in impact, excessive mirage boiling off the barrel obscuring your sights? Or how about your weapon failing to function due to high cyclic rates, fouling, excessive high pressures, or your quick detach suppressor falls off? I have seen all of these problem not only in combat, but in competition and training as well. The O.S.S. suppressor guarantees that these issues will not be found on their product.

My Experience With the O.S.S. Suppressor

I was somewhat shocked by the way the suppressor looked. I hadn’t seen anything of its kind. The octagon structure of the suppressor caused somewhat of a shock, I decided to run the M-4 as I would with any other weapon, hard-core! The M-4 platform the suppressor was attached to was an old, un-maintained weapon, full of carbine, uncleaned, etc.

Now time for testing accuracy with the suppressor attached. A target 100 yards away, measuring less than 10 inches wide and 8 inches tall, was the perfect test for such a rifle, well within the weapons prescribed performance. I took a few shots at it kneeling and standing, connecting on the steel plate every shot. Connecting with the target was not the surprise. The amount of recoil and sound reduction shocked me the most.

With the O.S.S. suppressor, I was able to perform a rapid fire string at distance on a small target due to its amount recoil reduction. Being able to get back on target with little effort is key in real life or competition environments. The recoil was almost less than a .22! Another key noticeably I found using the O.S.S. suppressor, was the fact that I was able to clearly see the target. This was not only due to it’s no gas blow-back, but by its ability to eliminate mirage rising from the suppressor into the sights, unlike other suppressors where the heat mirage can obscure the sights and target. This is due to the shape and structure of the suppressor. The octagon shape disperses heat away from the top of the suppressor/sight alignment over the bore or surface. The heat of the suppressor disperses through the sides, allowing the shooter to clearly see the target and sights.

O.S.S. Specs

Weapon system overall length increase – Is the overall length added to your weapon with the components on. Exactly how much we are adding past your muzzle.

Unit length behind/in front of muzzle – This measurement allows you to see the exact dimensions being taken. With Flush Mount (FM) it allows you to see the additional length that is added onto your weapon.

Unit weight in front of muzzle- Over The Barrel (OTB) gives you the advantage of bringing your axis point back to a more centralized & balanced location allowing you to handle/drive your weapon. All we are doing here is showing you the additional weight that will be added past your muzzle and how it will physically feel. Flush Mount (FM) adds a significant weight past your muzzle when compared to OTB.

Total unit weight – The exact weight of our components and system as a whole.

Point of impact shift from 32 F to 600 F ( 0 C to 315 C) – This is the worst possible shift you will ever see on our suppressors. To advertise zero POI is a ridiculous lie in the world of suppression. You may as well claim zero POI shift on a cold bore shot as a rifle manufacturer. At 20 rounds per minute and a constant suppressor temperature, our devices have zero shift. In a real world combat situation, those conditions are never guaranteed so why use them as a standard. OSS always defaults to the worst case scenario.

Peak visual signature including 1st round – Currently the first round bloom is and has not been considered relevant in the selection process of suppressors. Why? Because the flash is so large the reading throws off the average. We believe your first round is the most critical and a massive first round flash gives your position away immediately. Once again, the standard is the worst case not the best.

AVG decibel level cold (under 200F/93C) – This is the AVERAGE decibel level when firing with a cool suppressor.

AVG decibel level hot (over 400F/205C) – This is the AVERAGE decibel level when firing with a hot suppressor.

AVG decibel level hot (Sustained auto fire) – This is the AVERAGE decibel level when firing in quite possibly the fight of your life and on sustained full auto.

Bolt velocity/rate of fire increase – OSS averages 6%, typical industry leaders measure from 28 to 44 percent increase.

Mirage intensity reduction on-line of sight – Once again 60% is the least amount we ever reduced, worst case scenario, this was on full auto as well.

Automatic Fire Capable – Our components are all capable of firing reliably on full auto.

Caliber Convertible – You can switch between calibers if you have the different cores for each caliber while utilizing a singular exterior housing. For example, you can change between 5.56 and 7.62 or .300WM and .338 LM, but not 5.56 to .338LM unless specifically requested and designed to do so .

Maintenance Sustainable Rate -20RPM – This is the bare minimum that our suppressor’s core will maintain our standards given this rate of fire. When performance levels begin to drop, the primary internal defectors are replaced. This replacement brings the unit back to its original performance level for another round count starting from zero. The suppressor can absolutely be fired indefinitely without replacing the core deflectors. This round count is an honest determination of where performance deterioration BEGINS, not where functionality ends. The outer housing components of the suppressor system are designed to exceed the life of the barrel and do not require replacement.

Maintenance Sustainable Rate -60RPM – This is the bare minimum that our suppressor’s core will maintain our standards given this rate of fire. When performance levels begin to drop, the primary internal defectors are replaced. This replacement brings the unit back to its original performance level for another round count starting from zero. The suppressor can absolutely be fired indefinitely without replacing the core deflectors. This round count is an honest determination of where performance deterioration BEGINS, not where functionality ends. The outer housing components of the suppressor system are designed to exceed the life of the barrel and do not require replacement.

Maintenance Sustainable Rate-850RPM – This is the bare minimum that our suppressor’s core will maintain our standards given this rate of fire. When performance levels begin to drop, the primary internal defectors are replaced. This replacement brings the unit back to its original performance level for another round count starting from zero. The suppressor can absolutely be fired indefinitely without replacing the core deflectors. This round count is an honest determination of where performance deterioration BEGINS, not where functionality ends. The outer housing components of the suppressor system are designed to exceed the life of the barrel and do not require replacement.
