He then went on to boresight the optic before removing it from its fixture and placing it back into the box. With the EBR chassis resting in a wooden fixture, an EBR builder picked an operating rod, guide rod and spring assembly from parts bins just a few feet away.
He started to build up the barreled action and checked for function before moving on to the next step. It was important to the builder that he verified that the unique Sage op rod guide was properly positioned on the barreled action. The red dot should face the muzzle when installed correctly. He then charged the operating rod to the rear a few times to ensure that the rod wasn't binding with the operating rod guide in any way. The builder then placed the barreled action into the tight-fitting aluminum chassis.
It usually required some type of encouragement from a small mallet with a replaceable nylon head. When the action was seated into the chassis, he rolled the rifle over and inserted a trigger assembly that he obtained from another nearby parts bin. With the action seated front and rear, he visually checked for the alignment of the chassis' holes to ensure proper alignment of the coarse-thread screws that wear red Loctite on the threads.
The fore-end of the chassis was now secured to the operating rod guide at three points, which would effectively free-float the barrel ahead of this guide. This feature of the Sage International chassis system had shown itself to stop barrel whip. A key point was that no pressure is put on the barrel. A special stainless-steel washer slid over the barrel to properly aid in the piston assembly's function. A new piston assembly then slid over the barrel and was screwed on with a special wrench that helped align the gas system.
The M14's legendary gas system was completed when the builder screwed on the gas cylinder plug. After sliding the front sight assembly across the dovetail of the flash suppressor assembly, the builder tightened it with a pair of pliers designed specifically for the M14 castle nut. Before reaching this stage in the build process, however, the flash hider has had the bore size increased.
The standard muzzle device was opened up with a 7 tapered reamer, which helped to prevent a phenomenon called water-drop deflection at the muzzle. With the stock installed, the builder worked on securing a solid platform for the Leupold sighting system. He attached a cantilever base to the cartridge clip guide and secured the Sage International cantilever base to the chassis' top rail with the help of two tensioning throw levers. Though the cantilever base could be removed, it should've only be done in the event that the primary optic failed during battle.
You could remove the scope and cantilever mount if the warfighter needed to use the iron sights. Removing the optic by removing the cantilever base demonstrated that a soldier could expect the same zero repeatability and zero retention within one MOA if it needed to be rolled off the rifle. With the cantilever rail removed, the SDM was free to use the M14's iron sights as a backup sighting system.
Even when using just the iron sights, SDMs have been reported to have successfully engaged and defeated targets out to yards. Each rifle was shot to verify grouping and accuracy, and that target was included with the Leupold box and assigned scope. Some end users faced situations where they needed to use M80 ball. The recorded accuracy didn't take place until the tester observed that the rifle had begun to "like itself. This was one reason why they highly advised against any operator or second-echelon armorer removing the chassis system from the rifle.
Certain rifles settle in right away. At most, EBR testers allowed each rifle eight rounds, with an average of three to four bullets walking before stopping and revealing a group. Only once has a rifle ever been condemned at accuracy testing. During my visit, four rifles were tested and the poorest accuracy was. The best rifle produced an incredible. I couldn't help but let my mind wander and think of the reaction at the range that would be elicited from the soldier in Afghanistan who is ultimately issued this rifle.
Accuracy testing hasn't been solely limited to the Rock Island indoor range. Never having shot anything beyond yards before, one of the TACOM team members, Mike Petersen, was allowed to engage iron maidens during a training exercise at Ft. Lewis prior to a unit's deployment.
The EBR proved itself well out to If we can shoot it well, we know the soldier can do even better. This semi-auto sniper rifle dishes very high damage to zombies. A special edition to commemorate the 10th anniversary of CSO. Has higher damage and chrome effect. Trooper with M14 EBR. Obtained from Code Box.
Science Fiction. Brick Piece. Hunter Killer. Journey to the West. Universal Conquest Wiki. A little heavy as far as typical sniper rifle goes, but for a battle rifle or Designated Marksman Rifle DMR , it feels about right. The Chassis is machined from high strength aircraft grade aluminum and has a removable Kydex forend and comfortable ERGO pistol grip.
Wanting to keep it unique, the stock received a hydro dipped coating by US Tactical. He chose to have the chassis coated in multi-cam while the telescoping butt-stock, Harris bipod mount and dust cover were coated with very a complimentary coyote brown accent. The work of US Tactical was very good, detailing the rifle all the way down to all the screws. Not only is the piece esthetically pleasing with the coyote brown accent, but it serves a functional purpose as well.
Ergonomically it is comfortable and friendly to shoot and the recoil is quite tame. The cheek rest is wide and stable and allows for a consistent cheekweld, though it is a Kydex material that can get a bit slick when sweat, grime, dirt and face paint is involved.
Typically some moleskin can help here. It does need to be noted also that while firing, we noticed the screws loosened enough to cause the cheek rest to wobble. On an additional note, it is common practice for us to use a sand sock at the rear during our accuracy tests but due to the angle of the buttstock we found it difficult to maintain consistent support with the sand sock. This may only be an issue to consider if you are dedicating this rifle to long range engagements from the prone position, but when used in a Designated Marksman DM role this may not be an issue.
The M14 was never a light rifle which was one of the reasons why the M16 was developed and chosen as its replacement, and that weight is present with this EBR as well. The overall rifle has considerable heft to it, nearly 13 lbs without any optics, bipod or ammunition. This is probably a bit excessive for a battle style rifle, though its right in line with typical sniper rifles today.
Whether it is too much weight is left up to the individual operator and agency or group. The high weight does help control recoil. For the shooting portion of this evaluation we used one of our tried and true Leupold MK4 4. This is a nice convenient mount that allows easy removal of the scope in case of failure in order to access the iron sights. While we typically advise against any removing of the day optics on a precision rifle, for an EBR setup it is a nice addition as the role of the rifle is a bit different.
