About Noveske Rifleworks

Noveske Rifleworks is devoted to improving the modern battle rifle, with a focus on a combat ready weapon capable of precision accuracy with 100% reliability. Noveske's stringent quality control procedures insure that all Noveske rifles offer a tactical advantage over any other AR rifle for sale on the market today, whether you're on the battlefield or in the streets. Noveske rifles are available for sale in several different configurations for mission specific requirements.

Features of Noveske Rifles

Noveske NSR Handguard

With a width of only 1.48 inches before accessories, the Noveske NSR handguard was designed to be the lightest and smallest free-floating forend available for the M16 family of weapons.

Stainless Rifle Barrels

Noveske stainless rifle barrels are made to fill a precision role and to provide flawless function, with proprietary chambering that allows for unparalleled accuracy and reliability. Noveske rifle barrels use steel that is a type of 416r, which is hardened to about 30 HRC prior to any machining.

These barrels are made with Noveske's proprietary PT buttons, which have a slightly more trapezoidal shape than in other chrome lined barrels. The type of stainless steel used prevents the lead edge of the rifling from eroding as quickly as conventional rifling, and Noveske barrels tend to last longer as a result.

For their edge in accuracy and excellent reliability, Noveseke Rifleworks recommends the stainless rifle barrels for use in any precision application.

Chrome Lined Rifle Barrels

Noveske's chrome-lined rifle barrels are cold hammer forged, which hardens the steel around a rifled mandrel to create the lands and grooves. These rifle barrels are chambered in 5.56mm NaTO and then chrome-lined to the specifications for an M249 machine gun, which is about twice as thick as that of an M4 barrel.

The end result is that Noveske rifles for sale with the chrome-lined barrel can be put through anything day after day, even with high rates of fire and exposure to high temperatures. For any high round count, high temp, and heavy shooting, Noveske recommends its chrome-lined barrels.

Noveske Switchblock System

With the increased (and often mandatory) use of sound suppressors in today's military and law enforcement M16/M4 weapons, a number of issues have arisen:

  • Increased bolt speed/premature bolt unlock
  • Increased chamber and receiver area fouling
  • Increased cyclic rate on Auto
  • Increased wear on weapon components
  • Increased recoil due to increased bolt carrier group/buffer impact on the rear of the receiver extension
  • Increased propellant gasses directed to to the shooter's face
  • Premature weapon failure during suppressed use

Unsuppressed Cycle of Operation

The expansion of the cartridge case neck against the chamber wall seals the propellant gases from leaking around the case. The propellant gasses expand, forcing the projectile through the bore, past the gas port and out the muzzle. The gasses passing through the barrel's gas port, travel rearward through the gas tube and expand in the bolt carrier group, ultimately resulting in the rearward movement of the carrier and the extraction of the spent cartridge case. During the weapon's cycle of operation in unsuppressed use, the bolt unlocks and extracts the spent cartridge case once the propellant gas pressure has been reduced to a level that allows for minimal carbon fouling on the chamber and receiver walls.

Suppressed Cycle of Operation

With a sound suppressor in place, once the round exits the muzzle, the sound suppressor begins to collect the propellant gasses. The sound suppressor then holds and delays the exit of the propellant gasses through the front of the sound suppressor, which also delays the normal reduction of propellant gas pressures throughout the bore and chamber.

Simultaneously, the gasses passing through the barrel's gas port travel through the gas tube at a higher volume and expand in the bolt carrier group more quickly than the weapon is designed to handle. The bolt carrier begins its rearward movement prematurely, which extracts the spent cartridge case before the propellant gas pressure has been reduced to the safe level. Once the spent cartridge case is pulled out of the neck area of the chamber, the carbon-rich high-pressure propellant gasses escape to the rear around the case and coat the case and chamber walls with carbon.

The carbon continues to move to the rear into the receiver area, coating with carbon the receiver walls, bolt carrier group, and the unfired cartridges loaded in the magazine. This results in a layer of carbon that will cause malfunctions as a result of a stuck cartridge case in the chamber, or a failure to feed or eject because of increased friction between the bolt carrier and the receiver walls.

The shooter will experience a blast of pungent propellant gasses directed at his face, causing difficulty breathing and seeing. The result is premature weapon failure during suppressed use.

Noveske's Solution - The Switchback System

With the use of the Switchblock System from Noveske Rifleworks, all of these problems associated with the use of a sound suppressor are addressed and corrected.

The gas port diamater of the barrel is effectively reduced to restrict the volume and pressure of propellant gasses to a safe level prior to spent cartridge case extraction. The spent cartridge casings are visibly cleaner, the bolt carrier and receiver are coated with carbon at a slower rate (compared round for round with an unregulated suppressed weapon), and the chamber remains cleaner. Unfired cartridges in the magazine remain cleaner prior to their entry into the chamber.

Other benefits of the Noveske Switchblock System include:

  • Reduced Recoil
  • Normal cyclic rate on Auto
  • Faster target acquisition/reacquisition
  • Increased round count through the weapon between cleanings
  • Increased weapon performance with sound suppressor use
  • Reduced wear on weapon components
  • Reduced propellant gas exposure to the shooter's face

The Switchback System comes standard on the entire line of Noveske Rifleworks rifles for sale.
