Hi there. I'm wondering if anyone has bedded a USGI M14 fiberglass stock yet, and if so what have the results been?
Also, I'm looking for advice on stiffening the forestock on these types of stock. They are very thin and very flexible in the forearm area, thus making the installation of a bipod a detriment if u are trying to milk the most accuracy out of these rifles.
I have relieved the front ferrule a fair bit per national match specs to avoid contact of the ferrule and the gas cylinder but with the stock being so flimsy it doesn't take a whole lot of pressure applied to get contact again.
Mind u, the rifle is shooting 1" as of now without bedding using my handloads with 168 matchkings.
I don't have the funds to spring for a MacMillan, and don't want to go to a match grade wood stock unless I find it necessary.
If anyone has done any of these mods please share your input.
Thanks,
AG.
 
Aha. I guess if he doesn't jump in this thread I'll pm him.
There was a fellow a while back that posted some pics of GI stocks that he had modded but I can't remember the name. They were phenominal looking. Obviously he knows how to work fiberglass by what I saw in his pics. I think he may have been from BC though I can't recall for certain. I guess I'll throw this in here too, where can one source the Rooster33 cheeck rests and spring guides in Canada? Can u purchase direct from him, or is someone carrying his products to distribute for him?
Thanks again,
AG.
 
AG, PM sent !

I did mods to a few M14 glass stocks. I can sent you pictures of hpw I rienforced the forestock of those stocks.........it's not that hard....but the house stinks and the wife aint happy !:D
 
M14 Stock Fun

I'm right here, but my wife is calling me up to watch a DVD movie with here. Back in a couple of hours to discuss ways of stiffening up the USGI glass stock so that it's nice and (torsion) tight for competition shooting at long ranges.

BRB,
Barney:eek:
 
M14 Stock Fun

Okay I'm back ! :p

I've had success using simple 10 oz. fiberglass cloth from Cambodian Tire. Boat repair resin that "I started with you". Just had to slip in that plug for Ukrainian Tire. :)

I cleaned off the inside stock channel with Acetone and then laid down several strips of 10 oz cloth. I cut the cloth to about 1.5" wide and just kept on laying down the layer from NORTH of the magazine well to just South of the sling swivel plate. I ended up with about 15 layers of cloth and resin. Almost looked like I leveled off the hogged out stock to smooth up the interior profile. :D

That front end was stiff as heck after I let the glass cure for 24 hrs. Now I felt confident I could drill and tap a QD sling swivel stud into the stock as long as it did not interfere with the op rod's travel. ;)

What was nice about this upgrade was that I did not alter the exterior appearance of the M14. Everything looked factory USGI issued and it was a clean looking stock. Have at 'er and show us your upgrades !!

Cheers,
Barney
 
I love that idea and how it kept the stock looking... well, for lack of a better word, stock. Could you post some pictures of what the inside of the stock looks like when you were done so I can get a better idea of how much you laid in there and how far down the stock it went?

Thanks,
Mark

I would love to post pics of this project, but sadly, I've sold that stock long ago. Any other CGNutters have success with this upgrade ?

Cheers,

To do the same thing but save a bunch of weight, glue in a couple of carbon fibre arrow shafts. Just glass below and above it making sure that there are no air bubbles around the shafts and cloth. You will use 1/3 the layers and end up with the similar effect.

Difference is you will have to use epoxy resin instead of fibreglass resin. Make sure you degrease and scuff up the shafts too.

Hi there, I sent u my e-mail addy but haven't got a reply from u yet. Did u get my e-mail ok or did it get lost in space somewhere?:)

So all of u guys are building up the inside of the forestocks and no one is building up the outside. I assume u guys are maintaining enough clearance of internal workings by doing just the inside and all have seemed to be plenty rigid enough? When I look at the MacMillan M1A stock it seems to be much thicker outside dimentions in the forestock than any other. Would it be overkill to strengthen it by the method u guys are describing and build up the outside as well by about 1/8" or so? That should make it rock solid should it not? I'm concerned about maintaining enough clearance inside the forestock.
Its all been great info so far but getting back to bedding the action into the stock, what do u guys recommend for this operation and where can it be purchased or ordered?
 
adding 1/8" inside the forestock is the maximum you can go. Otherwise, you will interfere with the op rod. You could add 1/8" to the outside of the stock but it will be mutch more work to blend the curves to the whole stock and fit the handguards. The complete process I did on the pics I sent you took about 10 hours........if you do the outside also, add another 10 and then add about 15-20 hours to blend and reshape all the curves so it still looks and feel alright.....
 
From a purely physical veiwpoint, the additional material on the outside would be much more effective in stiffening the fore end. However, then it doesn't look stock anymore.
 
You are right..........Doing so would maximize the inertia of the stock.....but like you said.....it doesn't look stock after that.....and is much more work to sand and blend the curves...
 
Stock Profiling

Simonyzer is right.. it's a lotta work to sand and then blend the curves.

I've done this kind of work to the exterior of the stock also. I've made up about 3 or 4 (lost count.... :rolleyes: ) of the glass stocks into what I call "McMillan Fat Bastards".... I used to compete with a SA M1A bedded into a McMillan stock and it was qutie fat and of course, very heavy. The US National Match course of fire that I competed in 20 years ago did not require any rundowns like we do in Canadian Service Rifle Matches so they can get away with super heavy NM rigs.

The blending did take many , many layers of fiberglass cloth and resin. I even pigmented the resin (blue is very easy to do....) and then slapped the liquid resin all over strips of fiberglass cloth along the forestock. Then after each half dozen layers of strips (3" wide or so... :cool: ) I would let the mixture cure overnight and then carry out some energetic rasping.

The net result ? A super stiff front end for my Douglas barreled Norinco M14's to turn into "precision rifles" so that I can shoot the Sniper matches at Base Boredom's Mons Range. :D

Give this a try.... you can only improve your groups with a stiffer stock... ;)

Cheers,
Barney
