Rockite or ???

I want to stiffen the for-end on a plastic stock. I watched a video using Rockite. Is there something better I can get possibly local that works?
 
Just a few videos I watched. That's what they were using. It adds some weight that I really don't need. It seemed pretty easy to use though. Its probably not the best idea but neither is wasting much time on this stock. Just trying to get a little tighter groups on a dime.
 
Rockite works great on plastic stocks. It dries white and can be painted. Mixes easy and dries quickly. I have used it on both Savage and Remington stocks and it is still working fine after years of use. Does add a little weight but how else can you stiffen it and not be heavier. I won't use anything else on plastic. Fill it just below the top edge of the webbing. On my a Savage stock I bedded the recoil lug with epoxy after doing the rockite and proper cure time. Its cheap and easy and would never thought it would work until I tried it. (Buy the smaller box as it don't take much.)
 
My tc venture stock was very flexible, poi changed several inches when switching between lead sled, bipod or bag. The forend is sort of honeycomb structure. I used a piece of heated #9 wire to make holes at the bottom of the the walls and used 1 hr 2 part clear epoxy( loctite brand, on sale for 2.00,took most of 2) and stopped short of the top of the plastic so I wouldn't need to sand. No flex after and no more poi shift between rests. Rifle is a 338wm. No issues since the work in 2016.
 
I honestly don't know much about it other than no one in the Tulsa area sells it. Guess I go to plan "B" when I figure out what Plan "B" is.

The rifle I'm messing with is a Savage Mod 12, 308 HB. The stock is kinda like a varmint stock and actually is pretty stiff and I don't mind it to much. Actually kind of like it. I thought with a little work and some paint I might make a decent stock of it. If the rifle performs, maybe after the Holidays and my bank account recovers, I would get a good stock. Just don't want to spend a bunch before the holidays.
 
I went to Lowe's, Ace Hardware and three Walmart's today. No luck at any of them. Thought I might try Home Depot tomorrow.

How would fiberglas resin work? Its everywhere it seems.

Sutherland's on 21st shows to have it in stock,1 lb. for 2.97.
I would call them and check as their website is not always accurate. 918-627-0777
 
Fiberglass resin would work. It is likely less dense than Rocktite so it weighs less than an equal volume of Rocktite.

Some resins are easy to work with and some aren't depending on the type. Anything available in consumer quantities should be fairly easy to work with. Read the directions if in doubt.
 
Hog out a channel for a length of aluminum square bar into the forearm, then bed it with Marine Tex or steel putty or similar. Works very well.
 
I found Rockite this morning at a little Hole in the Wall store. I cut a steel rod about the length of the fore-arm then poured the Rockite over it. I just built it up just shy of the top of the ribs in the stock. Now we wait! After its all cured, I plan to bed the action with Marine Tex. The stock weighed just a hair over two pounds before the rod and Rockite. After it dries I'll weigh it again to see how much weight it added. If it works, it was a cheap fix. The small package of Rockite was only $2.00.

On a FYI, a little bit of water goes a long way. I found out the hard way....as usual!
 
Well, the Rockite job is done and here's what I found. The fore-end was pretty solid to begin with and had very little up and down flex and no large amount of side to side but you can see the stock moving when pressure is applied. After the steel rod and the Rockite installed, I see very little to no difference in the stock. On a rest or bipod, the barrel is still free floated.

What I read before the job, was most of the flex in plastic stocks come from around the action area and thats the part that needs the most attention. What I didn't read is how to fix it.

So basically the Rockite didn't hurt anything other than adding a few ounces of weight, but the rifle will see mostly bench shooting so the weight doesn't hurt.

The freezers full of venison and I'm done deer hunting, so it was a fun project and I found out that while it may help other stocks, it didn't help this one very much and time and a couple of bucks is all I'm out. The rifle shoots good and maybe a little stiffer fore-end may help. Another trip to the range will let me know.
