M110K5 M-LOK

M110K5

The M110K5 is a suppressor optimized 7.62mm carbine. A precision 14.5 inch barrel combined with direct-thread semi-permanent suppressor options significantly reduces the length and weight normally associated with suppressed 7.62 platforms. An ambidextrous bolt release, selector, and magazine release offers the left-handed user the ergonomic advantages inherent to AR15 based controls, as well as giving right-handed users alternate methods of manipulation to increase efficiency of movement. The Drop-In 2-Stage Trigger serves double duty as an aid to long range precision marksmanship while enabling surgical speed shooting at close range.

Pressure Reduction

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.

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.
