Still need the SAGE crush washer, a couple of pins, parkerize a USGI NM op rod guide, and installation of the faux M14 selector lock, but this replica of an early Mk 14 Mod 0 is is getting closer. Receiver is a 2010 era 237k SAI M1A. I owe a HUGE thank you to Crazynoto for this project, as he had to do some milling on the medium weight Criterion barrel to allow it to fit this early SAGE chassis, and he also knurled the barrel and carefully installed the SAGE op rod guide block for me, etc.
First, here's two pics for inspiration. The 2004 era SAGE chassis on the earliest Mk 14 Mod Os had a full length 13" forend, and it was field tested in limited numbers in Afghanistan. Many of these early chassis were un-marked by SAGE on the right side, they were simply blank. These rifles also had standard length 22" barrels and not the shorter 18" barrels that are commonly seen on the production Mod 0s. They all used the unique NSG aluminum Badger Ordnance (and Crane specified) MK 14 Mod 0 rings with see-thru window that allowed the use of the rear sights - in case the scope became unserviceable.
The pictures I have seen of these early Mk 14 Mod 0 rifles all seem to be US Army troops, in particular Army Airborne Infantry soldiers, which is sort of interesting. I guess their command had asked for, or allowed, SOCOM/Crane to field-test these new SAGE M14 chassis many years ago...This is one of those early 1st generation, unmarked SAGE chassis in NSG (Navy SEAL gray) (Date is unknown):
DoD picture file name refers to 2nd Battalion, 503d Airborne Infantry Regiment, in Afghanistan.
Here’s pics of this project that started slowly back in 2020, but it's finally getting close to assembly.
This style of marking is the so-called "dot matrix patient pending" chassis. Probably made circa November or Dec 2004, per Kevin (aka H20 Man) who has a lot of knowledge re the early SAGE stuff. It has the various 'lightening' holes that Crane requested for the Mk 14 program in Nov 2004, but it still has the long forend of the first generation chassis. Beginning in 2005 SAGE shortened the chassis by 1.75" and the 'dot matix' style font was replaced with deeper laser engraved lettering.
Got lucky with an original Navy Mk 14 bolt via some trading of parts last year. I owe a big thank you to NukeWorker who sent me that little SAGE scope mount for the rear clip guide (to the right of the bolt). It's a small discontinued part, but its essential for an accurate Mk 14 Mod O replica.
The one notable deviation on this replica MK 14 Mod 0 project is that instead of a standard profile USGI M14 barrel, I instead used a chrome-lined, medium weight Criterion barrel, 1/11 twist that was made for LRB Arms. However, it’s diameter required a relief notch milled on the left side to allow it to fit this early 6-hole top cover. The original SAGE chassis accommodated only standard USGI profile M14 barrels. (SAGE later started offering a 5-screw top cover that allowed the use of medium weight barrels, as seen on the M39 rifles).
Chrome-lined chamber. Headspace was 1.631" w/ Mk 14 engraved bolt, so I was happy about that.
Crazynoto’s handiwork regarding the required relief notch. In addition, he also knurled the area under the SAGE op rod guide. It's a press fit, but without a roll-pin, which should allow for a little bit of thermal expansion of the barrel, at least in theory.
The interior shape of the six-screw top cover fits down into that relief notch, and thanks to this cut there is plenty of clearance so the barrel now fits, and can't rub against the chassis or top cover.
Also seen are some original Mk 14 multi-tools. The SAGE vertical grip is a slightly older design, but unfortunately it's not the earliest design, as I have not seen one for sale.
Quick history on the 1st versus 2nd generation SAGE chassis. The soldier feedback to Crane/SOCOM was that the chassis was a bit heavy and thus Crane had SAGE shorten the forend by 1.75" to lighten it slightly (by 4 ozs). Multiple "lightening" holes were also added to reduce weight. In early 2005 these changes were incorporated into the so-called "chop-mod" chassis that most Mk 14 Mod 0s utilized, along w/ the shortened 18" barrel and an SEI flash hider. However, I decided to built the earlier version with a 1st generation SAGE chassis, along with the standard length 22" barrel. The early aspects of this replica Mk 14 sort of fits my collection interests, and hopefully I can finish it in the weeks ahead.
Like my replica USMC M39 that is also in progress, this replica of an early Mk 14 Mod 0 project was difficult to piece together one part at a time, and thus it took a few years to get to this point. I’ll post some follow-up pictures once it’s completed.
