BCM | 300 Blackout
Bravo Company Manufacturing has released a full line of 300 Blackout carbines and upper receivers. With this latest addition, BCM has officially entered the 300 blk segment of the firearm industry. The many similarities in the components of the weapon platform between .223 (or 5.56) and 300 Blackout allow an easy and cost effective caliber conversion.
In the past few years we have seen many other companies entering the 300 Blk market; we are very glad to see one of the best firearms manufacturer following the same steps. BCM will be offering the 300 Blackout upper receiver in 16″ RECCE, 12.5″ CQB and 10″ Pistol lengths.
Approved by SAAMI on 17 January, 2011, Supersonic 300 AAC Blackout 110-125 grain 300 Blackout ammunition was designed to produce a similar ballistic effect on target of a 7.62 x 39 mm round but out of a 9″ barreled AR platform carbine. At 300 meters, 300 Blackout has 16.7% more energy than a 7.62 x 39mm round. A supersonic round fired from a 9″ barreled AR pattern 300 Blackout carbine will match or exceed the energy at the muzzle of a 14.5″ 5.56 M4 carbine.
BCM 300 Blackout carbines use the exact same components, down to the magazines, as the rest of our carbine fleet with the exception of the barrels. This also means an end user can utilize both their existing magazines and AR accessories to fine tune the feel of their carbine, same as any other M4 or Recce rifle.
The 300 Blackout line of BCM carbines are built on our 1:7 Twist 11595E Certified Steel barrels. The bore on each BCM Enhanced Barrel is honed to perfect the rifled finish prior to chrome lining both bore and chamber. With a continuous taper profile designed to optimize balance, performance and weight; each BCM barrel is fluted toward the rear near chamber, increasing strength and speeding heat dissipation. Barrel harmonics and accuracy have been further improved by removing the sharp handguard cap shoulder commonly associated with AR platform barrels. Reliable, mil-spec quality, BCM Enhanced Barrels will deliver a repeated positive effect on target, every time you press the trigger.
For more information about the 300 Blackout caliber, its conversion and its performance (also at distance) please take a look at what Travis Haley from Haley Strategic Partners has to say after one year of test and evaluation with this platform.

Magpul M-LOK System
HISTORY
In late 2007 Magpul Industries Corp developed the Masada Concept Rifle that featured a polymer hand guard with three elongated vent holes that acted as a negative mounting surface for accessory rails.
These slots became one of the first “negative space” attachment systems that allowed 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
allowed direct mounting of accessories, such as fore-grips and flashlights, with no rail interface needed.
In 2009 the MOE hand guards for the common AR15/M16 firearms were released, bringing the same slot system, along with rails, flash light mounts, grips and other accessories to the mainstream.
In the years since the MOE slot system has been released, several million MOE slot compatible accessories have been produced. Initially introduced as a Magpul-specific system, several other companies have built MOE slot compatible accessories in the years
since its release.
The MOE system was never officially released as an open standard, and the requirement to have access to the back side of the mounting surface limited its application.
Additionally, depending on the accessory item, the spacing increments were not always small or uniform enough for desired placement. These characteristics made MOE slots and accessories less ideal to use with free-float hand guards, which did not allow
back side access to the mounting surface. Rather than documenting and publishing the existing MOE slot information and weld nut system, Magpul engineers used this opportunity to substantially improve the feature set of the MOE system. The result is the M-LOK.
M-LOK
M-LOK stands for Modular Lock system. The M-LOK system retains an elongated slot appearance, similar to MOE slots (with different dimensions). The new slot is larger, has squared sides, and the new system adds the following feature set: M-LOK
• DIRECT MOUNT CAPABILITY
• CAMMED T-NUT
• OPTIMIZED FOR METAL AND POLYMER MANUFACTURING
• RECOIL/IMPACT MITIGATION LUGS
• INTERMEDIATE SPACING OPTION
• MULTI-DIRECTIONAL MOUNTING
• BACKWARDS MOE COMPATIBILITY
FEATURES
DIRECT MOUNT CAPABILITY
Accessories are mountable directly from the front face of the slot. No access from the rear of the system is needed.
CAMMED T-NUT
The M-LOK direct attachment system features a custom, cammed T-Nut that positions the T-Nut consistently for installation and removal. Simply adjust the gap between the T-Nut and accessory to match the thickness of the mounting surface, align the T-Nuts
with the slot, and insert in the desired location. An initial ¼ to ½ turn of the screw for each T-Nut rotates the nut into engagement and then you may tighten normally.
OPTIMIZED FOR METAL AND POLYMER MANUFACTURING
Simple, rounded, rectangular slots with no sharp edges, complex geometry, or undercuts make the M-LOK slots optimal for high volume metal and polymer manufacturing
The M-LOK slots require no special cutters or angle gauges in the manufacturing process. With injection molding, the lack of an undercut allows simple mold design. All of this results in the lowest manufacturing costs possible.
RECOIL/IMPACT MITIGATION LUGS
Accessories feature recoil mitigation lugs with full recoil lug support in all 4 axes of movement, preventing movement of the system under recoil or rough handling, allowing repeatable accuracy in removal and reinstallation.
INTERMEDIATE SPACING OPTION
M-LOK accessories can be direct mounted entirely within a slot or bridging between/across slots, making the adjustment interval smaller than the size of a single slot. (Intervals equal two Picatinny rail slots (20mm) of adjustment). Full, 4 axis recoil lug support is maintained at every interval.
MULTI-DIRECTIONAL MOUNTING
Accessories can be mounted facing toward the front or the rear (180 degrees difference), with full recoil lug support—the system does not need to be oriented in a specific direction to function properly.
BACKWARDS MOE COMPATIBILITY
In addition to the soon-to-be released, dedicated M-LOK accessory line, current MOE accessories will work with the M-LOK slots via an adapter plate, giving the M-LOK system access to millions of accessories already fielded for the MOE system.
Desert Tech Introduces the Micro Dynamic Rifle at 2014 SHOT Show
On January 9th 2014 Desert Tech, formerly Desert Tactical Arms, has announced a new product for Shot Show 2014: the Micro Dynamic Rifle (MDR).
The MDR is a compact bullpup rifle. According to the official press release this rifle allows the user to convert, without any tool, between 5 different calibers. The DMR uses an innovating and patented system to eject the brass forward. It also has fully ambidextrous controls (mag release, fire switch, bolt release), which allows any operator to use this weapon in any position.
The DMR seems to be very portable with its compact and balanced design, with an overall length of 26″ (66cm). It also seems to have an even more compact version of 20″ (50cm) that utilizes a 10.5″ (26cm) barrel.
The weight of the gun waves between 7.12 lbs to 7.5 lbs (3.2 kg – 3.4 kg). The gun seems to be assembled with multiple polymer-made components, in order to lower the weight.
A key feature of all the Desert Tech products is the adaptability. The best way is to have a tool that can adapt to different mission configurations within minutes. Like other Desert Tech (former DTA) rifles (like the SRS, SRS-A1, SRS HTI) the Micro Dynamic Rifle can quickly switch between different calibers, but in this case without tools. The barrel exchange is designed to retain the barrel zero without need to compensate after the process.
About what calibers will this rifle utilize, to whom it will be available or other details we have to wait for Shot Show 2014.
With the release of this rifle Desert Tech aims to transfer its adaptable and versatile design from precision rifles to carbines. We will see very soon how the public will react to this novelty.
