I've been playing with my M1A Standard with great results for the past 3-4 years. I recently decided to take the plunge and undergo a little bit of modernization project, but not the typical route most would choose to go. I've gone from a Boyd's wood stock to a foliage green VLTOR Modstock. I delved into the guts to make some changes as well.

The new specs are as follows:

External

-2007 Springfield M1A Standard w/ H&R trigger group.
-VLTOR Modstock with eMod buttstock (comfort abounds w/ storage galore!) and tango Down Battlegrip
-Smith Enterprise Weaver M21 Mount (best $125 I ever spent on a firearm)
-TPS TSR-W Low rings (the best tactical style Weaver type rings on the market as far as I know)
-Nikon Monarch 3-12x42mm w/ side parallax adjustment & BDC
-Smith Enterprise Vortex flash hider, using original castle nut
-VersaPod Picatinny adapter sling swivel
-LaRue Integrated Bipod

Internal
-USGI extractor
-Sadlak NM spring guide
-Sadlak piston

General Comments
The rifle in its original configuration was a 2MOA rifle (10 shot groups). The trigger group has a nice pull and a crisp let-off, I feel no need for trigger work at the moment. Feels like it's around 5lbs, but I don't have a trigger pull gauge. Unified gas system will be coming soon. The trigger group fits the VLTOR much tighter than the Boyds wood stock. it is tight enough that I'm not sure if it will need to be bedded. I expect accuracy to be slightly better due to the tighter fit, combined with the other mods. The stock allows for a much easier handling rifle than the traditional stock. The eMod buttstock is great. It is very comfortable, and will allow me to have extended sessions. The eMod is waaay overbuilt for the 5.56mm in my opinion. With this setup, the stock extension is perfect when it is flush at the top. You'd have to have a tall scope setup to need it raised any higher. Folks may question the standard profile barrel, but this thing shoots! It will get rebarreled when the time comes,probably with a medium weight. the VersaPod adapter has a gap between the rail and the stock, but this may be by design, so that any pressure exerted on the stock is further away from the front band. The LaRue bipod is a huge improvement over a standard Harris. They made a new interface for it, rather than the clasp & small knob of the original. The large knob when loosened, allows the legs to swivel. It can be tightened down to correct slight canting issues or uneven surfaces.

I have been able to shoot the rifle for funtion testing, but not accuracy testing. The only ammo I have at present is Paki surplus and Remington UMC; not the best for judging accuracy. I will report back when I get to shoot some reloads through it. It also seems to really like Federal Powershock Soft Points.

Not your typical EBR setup. All told, it weighs in at 13 lbs. with an empty mag, measured on a bathroom scale. The scale is accurate to half pound increments.

Sweet looker there. Very classy design, love the fact that the fore-end isn't some jumble of picatinny rails. Brings the old Garand design into the 21st century for sure. No wonder the Marines brought them back into service!
 
Thanks t! I also love the fact that there is no unnecessary weight here. It's everything I need and nothing that I don't! In the end the weight is the same as my original setup in the walnut stock, except with many, many added features & bonuses.
 
Nice job on your build boricua9mm. I have a early standard with a Wilson six groove NM barrel. I had to send it back to SA for a bolt recall and had them do a NM trigger while they had it, best $25 I ever spent.

Have you looked into unitizing the gas cylinder. I had hueygunner over at M14 firing line do mine, very reasonable and great work. He can ream the FS but you don't need that with the Vortex. Unitizing the GC gave me one full moa increase, 2.5 to 1.5 moa with irons.

I have wanted to do a EBR build on one of my M1A's but being kind of a fudd I just could not do it. Got to have that steel and wood. I did satisfy the urge with a AR10, Armalite/Noveske build that is almost ready to shoot. Waiting on scope mounts.

Very nice rifle, more pic's.
 
Thanks madcrate, yes, I'm contemplating unifying the gas system. I've thought about shimming it, but I'm just not sure if that is permanent enough.

I'm going to run some more consistent ammo (168 reloads and the Federals that it likes) and go from there. I really need to establish a baseline so I can decide where there is room for improvement.

I've been getting a lot of questions about the stock itself, so I might be taking some more shots of it to show exactly what it is and how it is built by VLTOR.

Thanks again!
 
Nice. How is the cheekweld on that stock when viewing through the scope? Does your eye level fall a little low or is it ok?

BTW are you behind the boricuaDV youtube videos?

I have it setup where the cheekweld is perfect for the scope, mount, and rings that I'm using. The extension tube can go both higher and lower from where I have it. By adjusting the height of the tube, it can accomodate everything from an irons-only setup to a scoped setup that sits tall.

Yep, boricuaDV is my handle/channel on YouTube.
 
...and I'm pretty happy about it! I was able to print 5 shots at 100 yards into 1.7" firing from the bench with a bipod. The reloads that produced these results was 168 gr Hornady A-Max w/ 42 grains of Varget loaded into Federal Cartridge brass.

I'm just getting started on load development for this rifle and I'm not quote sure what to try out next. From today's shooting, I noticed that the same exact load with different brass seemed to produce different results, but I'm not 100% sure on that just yet...

Where should I go from here? I think 168gr Sierras would be nice to try out...

Oh! At the end of my session, a tattooed-up fellow who was shooting an AR came up and said "Nice looking rifle. Is that an SKS?" :D
 
hey i like your setup. i did one similar. i dont know why we dont see more of these stocks on standard m1a rifles. dont you have a youtube video on this rifle? anyway here is my gun at different stages. as you can see i opted to paint the black stock:

Skipbo,

Yeah, I have an overall video for this rilfe, the link is in the first post at the top of the thread. Just wanted to follow-up with the accuracy results. The Hornady A-Max seems to be well-regarded, so I may try a different powder. A lot of folks seem to recommend IMR for the M14. That way, I'll only be changing one variable at a time. We'll see if a different recipe can shrink these groups...
 
yeah, you have two videos on this gun. i ran across them like 10 days ago. i love the music you play. also, it is a very good over view of the m14/m1a.

i cant remember....did you say that you shimmed the gas system? i just did that to my gun and it shot a little tighter. 1.7 MOA is pretty good for a m1a with a standard barrel.
 
Thanks for your comments on the videos! Actually, I have not shimmed the gas system, but I've been thinking about it. In the long run, I'm probably better off getting it unitized for $50. I did change the gas piston to the Sadlak TiNi version.

Like you said, for a Standard profile barrel this seems to be doing pretty well. Especially considering the stock is not bedded whatsoever...
 
yeah, and a simi auto battle rifle is only going to get so accurate. i would get a bolt action before i bedded my stock. just too much hassle. M1As are 2-3 MOA guns IMHO but im sure with the tweaks you are doing you can get it down to 1MOA. so far i like all the mods youve done. they are simple upgrades that should have been done to the rifle in the first place.

on your vltor stock....when you put the bipod adaptor rail on it, did you have to file anything down on the inside of the stock (screws ect.) i think i need to grind some metal in the inside of mine because i think it might be touching my op rod.

I did not have to relieve the stock at all for the installation of the VersaPod rail. As a test, what I did was scrub the screw tops with a crayon before putting the action into the stock. I then closed the trigger group in to lock everything into place. After pulling the stock out, I looked for any crayon markings on the gas tube and op rod, and I did not see any. I would recommend doing this type of test to see if there is any contact. I've heard that chalk dust also works well for this.
