The U.S. Navy's Mark 14 Mod 0 Enhanced Battle Rifle (Enhanced Battle Rifle - EBR) is a variant of the M14 rifle. It was originally designed by the U.S. Naval Special Warfare Command in 2000 based on the requirements of the SEALs and solicited bids from firearms manufacturers.
The reason why the CQB considers using the M14 as a battle rifle is, on the one hand, because the penetration ability of 7.62NATO is very effective in dealing with vehicles, ordinary walls and other bunkers in urban warfare. On the other hand, it is because the performance of the M14 has been proven for many years.
They have been using the M14, and they even changed the M14 into a folding stock to facilitate use in narrow environments. After testing, they adopted the solution of Sage International Co., Ltd.
Development background
Sage International Ltd. is located in Oscoda, Missouri, on the west shore of Lake Huron. The company produces a variety of rifle and shotgun accessories, car gun frames and scopes. Sage's initial plan was to modify the existing
The fiberglass stock was modified by cutting off the original stock and installing a pistol grip behind the trigger guard, and then the telescopic gun originally produced by Sage for the Navy's Remington 870 shotgun
Put it on.
The modified rifle was sent to NSWC (U.S. Naval Surface Weapons Center) for trial use, and the feedback received was that a Picatinny rail could be installed on the front stock. At this time, Sage's designers had two options: ①
Use injection molding technology to produce the guide rail and the front stock together; ② Use screws to rivet the guide rail to the machined aluminum alloy front stock. In the end, they chose the machine-machined path and demonstrated it at the Orlando Gun Show in 2003
Their result. Sage Company named this system with a handguard and a retractable stock the EBR Chassis Stock. The reason why it is called Chassis is because it is just a metal handguard and stock.
The gun body, the M14 receiver, barrel, and action mechanism are installed together to form a complete EBR rifle.
Equipment status
NSWC formally signed a contract with Sage International to produce the chassis-type gun stock of the weapon, and then NSWC installed the M14 with an 18-inch barrel on this chassis. The SEALs began to equip the first batch of Mk14Mod0 in 2004. Inspired, the US coast
The defense team was also the second to start equipping Mk14Mod0.
The U.S. Army is also equipped with some EBRs, but the U.S. Army's EBR is provided by Ron Smith and Smith Enterprises Inc. and is modified from the M14 with a standard 22-inch barrel. Therefore, the Army's EBR is positioned with the Navy's Mk14Mod0
Differently, the Army's EBR is not used for CQB, but is provided for use by team snipers (fashionably called "precision shooters"). The M14EBR produced by Smith Enterprises is sometimes called MK14SEIMod0, while the carbine produced by Sage International
Model is also known as Chop-ModEBR.
The U.S. Marine Corps also considered EBR, and the EBR they finally equipped was additionally named the M39 Enhanced Marksman Rifle (Enhanced Mark**an Rifle).
Since Seal's Mk14Mod0 is mainly used for CQB, most of them are equipped with close-combat rapid sighting devices such as M68CCO, or ACOG or other variable-magnification low-power sights for close-range sniping (the fashionable term is "precision shooting").
"), but even if you install a 10x scope, there is no problem, because they are all M1913 Picatinny rail interface. In addition, it can also be equipped with accessories such as a front grip, a bipod, and a laser pointer. The Army and Navy
The Marine Corps' M14EBR is mainly used for precision shooting, and most of them are equipped with a 10x scope (of course there are exceptions such as red dot scopes). In short, what accessories are equipped depends on the needs of the mission.
Now Seal has begun to use the improved Mk14Mod1. In addition to slight improvements in the details of the handguard, the biggest difference from Mod0 is that Mod1 uses the CTR stock produced by Magpul Company. This stock is more comfortable to use. However, the stock of Mk14Mod0
The total gun length is 35 inches when retracted, while the CTR stock is not that short when retracted, with a total length of 37 inches.
Relevant information
The June 2006 issue of the British "Jane's International Defense Review" reported that in order to meet the needs of the Army's Special Operations Command (SOCOM), Sage International developed a base-type stock for the M14 rifle, transforming it into a 21st century enhanced
Tactical carbine, the military is designated as the Mk14Mod0 enhanced combat rifle. Currently, the M14 used by the Naval Surface Warfare Center in Indiana also uses this stock. Troops using M14 rifles can purchase enhanced combat rifle stocks to upgrade existing M14
Rifle, you can also purchase the Mk14Mod0 semi-automatic rifle directly from the Fulton Arsenal in the United States. The evolution from the standard M14 to the Mk14 rifle includes the following improvements: First, the barrel length is reduced from 559 mm to 470 mm, and the use of the Smith Enterprise "Vortex" (
Vortex) flash suppressor replaces the standard M14 flash suppressor, reducing muzzle flash by nearly 99%. It is very necessary to use a high-performance "vortex" flash hider for this carbine with a barrel shortened to 470 mm. Secondly, the Mk14 rifle utilizes
A "paddle" bolt stop similar to that of the M4 carbine replaced the original bolt stop, allowing the bolt to be opened without removing the trigger hand from the pistol grip, whereas the original M14 rifle needed to be inserted
After the new magazine is opened and the bolt is blocked, the bolt handle can be pulled back to open the bolt. This advantage is very useful on the battlefield where every second counts. Finally, the Mk14 rifle uses a 38 mm long Picatinny rail to replace the original
The magazine guide groove on the receiver can be used to install optical devices. The same as the test rifle. The guide rail can also be installed with Sage's enhanced combat rifle stock, which can make the basic Mk14Mod0 rifle more complete. For special tactics
For the troops, the Mk14Mod0 rifle makes up for the shortcomings of the previous 5.56mm rifle, while having the same flexibility and tactical effect.
