So in my quest for th e 0.5 moa m14(lol) i picked up a gi stock on the ee. Its nice, thin and lighter than my norc stock.

But it doesnt have any metal in it for support which the norc has. As well the forend doesnt have any structural support and has much more flex than the norc. My plan is to bed and replace the norc stock, are these gi stocks really better?

Remember that the USGI stocks are designed for killing zombies (dare I say it?) and combat and other nasty applications. LR bullseye shooting was not one of their primary objectives. That's where the USAMTU (US Army), US Navy, and Marine teams developed tweaked and purpose built (read: not for combat) National Match rifles (read: shoots small tight groups at bullseye targets that are static).

So what does a cheap tweaker like me do? I added another TEN layers of 10oz fiberglass cloth up in the fore arm / forestock of the USGI glass stock to ensure that the front end is super stiff like a McMillan M1A stock (google image is your friend here) without paying the $ 500 plus plus costs.

So can you make a silk purse out of a sow's ear ? Kinda, maybe, and possibly .... all in that order. Can you make it shoot small groups? Yup , if you throw lots and lots of money at it, been there done that... Now I just shoot a Remington SPS Tactical (both .260 and .22-250) for accuracy. Lots cheaper and fewer headaches. :D

Hope this helps save your money!

I like my USGI fg stock, but the flexible fore end is sensitive to pressure when shooting off a bipod or front rest. Best to keep the rest close to the magwell to minimize influence on the stock and barrel. Same with a bipod. Mount it closer to the magwell and don't load it through pressure. I find my gun shoots the best groups when I let it rest with by its own weight on a rest, and not leaning into it, otherwise you would have to be very consistent in the pressure you put on the gun. It's not like it has much recoil and needs to be heavily controlled.
 
Mine is flexy and I haven't done a thing to stiffen or bed it, but it can still turn in groups like this @ 100 yards with a 9x scope and handloads that I haven't put a lot of work into developing. My advice is don't worry until it's proven to suck. Pretty sure I got a boner before that last shot to the right. :redface:

hahahah awesome.

Just making sure I didnt buy an airsoft stock. I dont really want a 0.5 moa rifle......or atleast I didnt until I saw Soboreds group! :)

Imma give that a shot hungry Im gonna be bedding it anyways.

OT but SoBored, what is that load you used for that group?

That was a Winchester Large Rifle primer, federal brass, 40.5 grains of IMR 4895 and most importantly, (cause it's cheap), a prvi 150 grain FMJ. Mystic Precision sells them in bulk for $225 per 1000 if I recall.

I loaded 25 rounds for that day, 5 @ 40.0 grains, 5 @ 40.5 grains, 5@ 41.0 grains, etc. Just near the starting loads, and I got that group. The others where more around 1.5".

I always meant to get out there and push on up trying to find something that grouped as well but was a little hotter, but I changed my scope mount to an ARMS18 and couldn't find rings that worked for the scope I wanted to put on it. One day I'll load more rounds and get that Falcon menace 4.5-18x mounted and then we'll see what she can do with that glass.
 
I like the USGI synthetic stock, but their forend will flex when slung up tightly.
Reinforcing the forend is a must if you want better than battlefield accuracy...
Several years ago I had the rigid rail modification (RRM) performed on two stocks and the results were excellent.
The RRM stock is rock solid and it delivers the correct draw down needed to enhance accuracy.

I think this is the rail that was used > 11" rail

Does that RRM cover up the vent hole?
Reinforcing the front end is just done with heavy fiber rag? Or/and any other rigid material (rebar-like) added to the fiberglass resin?
My concern is weight.
 
I love the look of that RRM!! And perhaps the surpressor as well.... I did the 11 layers of fiberglass in my USGI stock, and also inlayed 2 1/4" rods of aluminum on each side of the op rod. (iv also heard of people using arrow shafts) but its not that crazy heavy. It's super stiff and still free floats.

No, a hole in the rail lines up perfectly with the vent hole.
I'll take and post some detailed RRM pictures later today.

BTW, simply bolting an 11" rail to your stock does not give you the RRM.
There is a method to the installation that preloads the downward draw.
I don't know the 'method' and the guy that was making these went MIA
with peoples stocks and money... he left with two of my stock and cash.

Any method used to reinforce the forearm will add some weight.
The RRM does what it's designed to do and it gives
you rail space for a bipod, grip and a sling swivel.
