Our Pressure Reduction system is a feature designed to
increase controllability and soften the rifle’s perceived recoil. This is achieved by
employing unique lengths in our gas tubes and buffer tubes. On the 16” SR25 EC and ECC
models we utilize a rifle length gas system coupled with a buffer tube that is ¾” longer
than the standard carbine length buffer. In some of the SR15 and SR16 models, KAC
employs a similar system of lengthened components to achieve the same result.
By using this setup, the energy released when firing is spread out over more time
within the weapon. This helps to relieve vertical kick in addition to a reduction in the
rearward recoil force that is absorbed by a shooter’s shoulder. Various parts in the
weapon system also see an increase in service life under this system. Our Pressure
Reduction system serves to increase reliability and decrease fouling, especially in
suppressed usage.
Multilog E2 Bolt
The E2 bolt design improves function and offers extended
lifespan. Dual ejectors provide significantly increased ejection force, ensuring
that the cartridge is cleanly ejected from the ejection port, even when using high
backpressure muzzle devices and collapsible stock systems, and provides a layer of
redundancy in the event of failure. The bolt lug design has been optimized and
stress-relieved, extending overall lifespan to not less than 10,000 rounds. The E2
bolt is completely backward compatible with M110 barrels and bolt carriers, and
utilizes many of the same parts as the legacy bolt design.
Quick Detach Coupler
The Quick Detach Coupler (QDC) line of Sound Suppressors
and Muzzle Devices are proprietary items designed for secure interoperability. The
coupling device itself consists of multiple ball bearings arrayed in a circular
pattern which fit into sockets specifically machined into various muzzle devices to
accept the QDC. The bearings are aligned with the sockets by way of a V-shaped notch
that seats the device onto an index pin. Once aligned, a simple twist of the outer
retaining ring locks the device securely into place.
This system was developed to provide fast and easy operation and
interoperability between weapons and suppressors. Knight's QDC line of sound
suppressors all feature this method of attachment. Various muzzle devices, such as
the QDC Flash Suppressors and the MAMS muzzle break, also feature the QDC pockets to
accept sound suppressors equipped with this coupling device. Secure interoperability
and intelligent, efficient design are the intended goals of this quick and easy
technology.
Ambidextrous Controls
Knight’s Armament designed this system to give shooters
the maximum amount of options in their controls. Under this design all of the
weapon’s major controls can be accessed from either side of the lower receiver.
Left-handed shooters see the immediate benefits of being able to access the weapon’s
controls in a more intuitive manner; however, there are a number of other benefits
that right-handed shooters will enjoy under this system.
Competition shooters benefit from these controls from the increase of speed
that is achieved through components such as the right-side bolt catch. Trainers
enjoy the variety of options because they can watch their trainee from either side
of the weapon and even manipulate the weapon’s controls from the non-operating side.
KAC has also introduced modifications to the design such as the scalloped safety
selector switch. This allows a lower profile for the selector switch on the
non-operating side of the receiver which helps to relieve any interference between
the switch and a shooter’s glove or hand. For the maximum amount of configuration
and operation options, Knight’s Ambidextrous Controls offer a sure solution.
Stage Match Trigger
All of the weapons available from Knight’s Armament come
equipped with a 4.5lb, 2-Stage Match Trigger. This type of trigger mechanism uses a
system where, during the rearward squeeze of a trigger, it cycles through two stages
of resistance.
The first stage is a ‘no-poundage’ stage where hardly any resistance is felt
during the rear-ward squeeze. There is a center point at which point resistance is
felt and the second stage of the trigger begins. At this point, 4.5 pounds of force
is required to squeeze the trigger through the second stage and cause the weapon to
cycle.
Our 2-stage trigger is meant to inform a shooter of exactly where their weapon is
going to fire. This bolsters a firer’s confidence and can also assist in reducing
trigger jerk, thereby increasing accuracy. The 4.5lb 2-Stage Trigger from Knight’s
Armament is a highly calibrated and smooth component that is sure to be a welcome
addition to any setup.
Carbon Cutter Bolt
The Carbon Cutter Bolt Carrier is a system Knight’s
developed to help increase reliability and longevity in our rifles, particularly
while firing suppressed. The serrated edges along the carrier’s lower edges serve a
dual purpose: The first is to pull away any foreign material; the second is to
provide an area for lubrication to pool.
The weapon will cycle and physically move the bolt carrier. When this
happens, the serrated edges will draw away any foreign material that builds up along
its path. This helps to provide a cleaner surface for the weapon to cycle through.
The second benefit to those serrations is that they provide an area for lubrication
to pool. Lubrication will normally be applied across the flat surface of the carrier
and wear off. The slight pooling effect gained by these areas helps to keep the
lubrication from wearing off too quickly and reapplies it when the carrier cycles.
The overall effect of this Carbon Cutter Bolt Carrier is a cleaner, more reliable
weapon over a longer period of time.
MLOK
M-LOK is a modular locking accessory mounting system
that is a direct attachment method for hard mounting accessories to a negative space
mounting point. The M-LOK attachment system allows the user to put mounting rails
only where they were needed, as opposed to covering the entire surface with mounting
rails, which are then covered with panels. The system also allows direct mounting of
accessories, such as fore-grips and flashlights, with no rail interface needed.
