My most challenging build yet: The Double-Lug M14 Login/Join 
Yeah, that M14 video guy...

My good friend challenged me to build a double-lugged M14 on a LRB M25 receiver with a McMillan M3A woodland camo stock. He chose a heavy profile Lothar-Walther barrel.

The front lug was made by a M14 forum member in Washington. He had the lug cut with a water jet and had two of them made. One for his project and the extra he sent to me, along with an alignment stud. Derrick Martin (retired now) used to do this same kind of lug on his double-lugged builds.

I had to cut about 0.200" off the barrel shoulder to accommodate the front lug.


The alignment nub and the lug...


The lug is sandwiched between the barrel shoulder and the receiver face...


The barrel hand-times around 15˚. Right where I want it.


Now I have to send the barrel off to be bead blasted and parkerized, then I'll finish the build. I've never bedded a double-lug, so it will be interesting.

Never seen anything like that. Looks like a solid design. Bet that thing will be a hammer.

Been following your work for some time Tony, I’m confident you will complete this build with relative ease.

Will be following this one.....

Wes came over yesterday and I did some more work on his rifle. I got the stock routed for the front and rear lug.

The McMillan he provided was not routed for any lug, so it was challenging getting the lug routed in the right spot without going outside the estimated lines of the receiver. it would have been very easy to rout the lug too far to one side, but I managed to get it right on the money. I was fortunate that the lug is tapered thin on the bottom and wide at the top. That allowed me some wiggle room to get it aligned into the heel of the stock.

Front lug routing...


rear lug routing...


rear-lug routing compared to a no-lug routing job. The difference is at the heel of the receiver and forward of the magazine well...


Receiver fully seated...


The cutout for the rear lug is nearly invisible...




These front and rear pillars will have to be bedded into the stock before I bed the action. I'll use the receiver and trigger group as alignment jigs.



Receiver with pillars illustration. The pillars will insert from the opposite end of the stock and will live there for ever...


Here's the front lug recessed into the front of the stock. I had to route extra for this...


Hoping to bed the pillars soon.

Tony.

Gents,

Had a great day at Tony's working on the rifle. He's a true gentleman and stellar host. Included dinner in the deal while I watched the master at work.
Tony is meticulous in all he does. I'm lucky to call him a friend, shooting partner, and a pal.

Thanks for your efforts, Tony.

Wes

Very cool! Thanks for sharing the photos and the process. Although I don't own an M1A (yet), I love garand-style actions and enjoy reading your posts and watching the builds.

What do you use for pillars? I have a couple stock projects on the back burner.

BB61-
It doesn't shoot yet. I still have to get the pillars in the right place, bed the pillars with draw pressure, hack up his operating rod to make it fit, as well as his operating rod spring guide, and bed the rifle.

After all that, it will be ready to fire. Wink

Voshterkoff-
The rear pillar is blackened steel that was included with the receiver from LRB. The front pillar is steel as well and was included with the front lug. I have made pillars before and I have always made them out of steel.

I'll wait with baited breath for the final report (and everything in between).

How much improvement over the standard military M14 NM rifle are you talking about here? I know the standard M14 was accepted at 4MOA, the NM rifle I had was 1moa with a glue in bedding job….

I'm expecting it will match my M14 in a JAE chassis, which was right at 1/2 MOA. This should be more consistent than no-lug M14's with heavy barrels and should not require a "settling time" after removal and installation into the stock.

That’s a lot of improvement, Benny. When I was close to retirement the CG had begun using the M14 in a Sage chassis and renamed the rifle the M14T. It was used in the armed helicopters and I didn’t work in that side of the house. I wondered how much a chassis system would do for accuracy. And going from 4MOA to 1/2 moa is considerable. Very interesting.

I've had some really good results with chassis systems. My two favorites are the JAE and the SAGE.

Here's one in a SAGE I built with a medium weight Kreiger 3 years ago. Sub-MOA on day 1...


And then there's my personal LRB in a JAE with a Walther heavy barrel. It averages about 0.6 MOA. I am also double-lugging this one as well and we'll see how well it performs after lugging, but here's my baseline.
