Historically, suppressors have been separate pieces of equipment that must be mounted onto a firearm with a quick release, threading, welding, pins, screws, or some other apparatus. By making the barrel and suppressor one and the same, Suppressed Weapon Systems’s Patent Pending Monolithic Integral Suppressed Barrel ™ (MISB) design is a complete reinvention of the traditional relationship between the suppressor and firearm.
Though older designs have ported the barrel and attached some sort of baffling system on the muzzle in an attempt to create an integral suppression barrel, this is not true integration. Rather, this is 100-year-old technology with a polished name that has all of the same problems associated with a traditional thread-on suppressor. The Suppressed Weapon Systems MISB has crossed that threshold and represents the quietest, most accurate suppression design on the market.
What is the MISB?
Suppressed Weapon Systems has reinvented the relationship between the suppressor and the rifle with a single, seamless design. When we craft one of our MISBs, the barrel and suppressor are both precision-cut from the same piece of material. Once our internally suppressed barrels have been completed, they may be installed onto one our accurized bolt-action rifles or AR platforms.
Improvements over Traditional Suppressors
While our Monolithic Integral Suppressed Barrel represents a significant overall improvement over traditional suppressors, those improvements may be broken into their component parts along the following guidelines, which will be discussed at length below:
- Heat dispersion
- Impact shift
- Back pressure
- Baffle strikes
- Sound suppression
Standard thread-on cans are small in size and heavy in construction, which causes them to build up heat quickly and then retain that heat after the weapon has been fired.
Since the MISB has up to 3.5x more surface area than most other suppressors on the market, our integral suppression barrels simply disperse heat more efficiently. Moreover, the very design of our MISB allows the heat of the entire length of the barrel to be reduced by 55% overall.
Since they change the weight of the barrel, conventional suppressors change the harmonics of the barrel once they have been attached. This would be similar to how additional weight on a tuning fork would change the tune of the fork.
Though this can be somewhat confusing, the basic idea is as follows: conventional rifles will have one impact point with the suppressor on and a different impact point with the suppressor off. The MISB avoids this problem altogether by utilizing a single piece construction, which allows it to maintain the same point of impact each and every time.
Fully-welded designs are the industry standard for thread-on suppressors. This design makes suppressors almost impossible to properly clean, especially once they have been submerged in mud, sand, or dirt. Since any obstruction will render suppressors useless and very dangerous, firearms and their attached suppressors must be thoroughly maintained and cleaned.
Suppressed Weapon Systems’s MISB is fully serviceable in the field with no more than a single tool—some models will not require any tools at all. With that in mind, all you would need to do is remove the end cap or gas block, remove the tube, and clean our integral suppressed barrel if it became filled with debris.
Cleaning the suppressor can be done with standard tools (bore and chamber brush). In some cases, removing debris can be done without tools (the back of a spent shell casing works well). The tube may then be reinstalled with the end cap or gas block.
Thread-on suppressors create a greater degree of back pressure in the rifle, which can be problematic for semi-automatic rifles in particular. Since extreme back pressure will increase the speed of the bolt, the increased recoil may damage the firearm. In bolt-action rifles, this can cause chamber pressure to rise to dangerous levels that are capable of splitting casings and primers.
Suppressed Weapon Systems’s MISB reduces the amount of back pressure in a suppressed semi-automatic platform. With so much available volume inside the MISB, back pressure associated with the suppression of the firearm becomes nonexistent.
Baffle strikes occur when the projectile makes contact with the suppressor. These incidents are extremely dangerous and may cause serious injury to bystanders and the shooter alike. Standard thread-on suppressors may be more susceptible to baffle strikes under any of the following circumstances:
- Improper installation
- Debris on the threads or crown of the rifle which may cause the misalignment
- Sharp impacts on the suppressor can bend or tweak the threads causing misalignment
Alternatively, baffle strikes are a near impossibility with the Suppressed Weapon Systems MISB. Since our integral suppression barrel is of a one-piece construction, there simply is no opportunity for a baffle strike to occur under even the most adverse of circumstances.
Inadequate Sound Suppression
Suppressor companies are not held to any national or international standards. As such, there are not any guidelines or regulations that determine how suppression companies manage the decibel ratings of their suppressors. Unfortunately, many companies release inaccurate or misleading dB ratings that contribute to hearing loss for shooters and bystanders alike.
At Suppressed Weapon Systems, our MISB has been thoroughly tested by third-party groups using state-of-the-art technology. Following Military Specifications (Mil-Std 1474D) for sound quality and OSA standards, Suppressed Weapon Systems has the most accurate Db ratings in the industry.
The MISB has been designed and tested to provide the best possible reduction of a firearm’s sound signature. All Suppressed Weapon Systems products equipped with the MISB are safe to operate without the use of hearing protection, including indoor shooting and CQC.
Traditional thread-on suppressors have a minimal effects on recoil reduction. In some cases, recoil is actually increased as the result of poor suppressor design that causes increased back pressure when the weapon is fired.
As a marked departure from traditional suppressors, Suppressed Weapon Systems’s MISB reduces recoil on all firearm calibers and platforms. Since the MISB efficiently redirects propellant gases, the recoil of a firearm may be reduced by up to 40% in some calibers.
