With lots of time on my hands this summer recovering from injury I decided to mess around and modify a tikka factory stock I’ve had laying around for a while. I’ve seen a bunch of the DIY stock build threads and figured I’d give it a go and see if I could accomplish this with the info found in those threads. Only stuff I purchased was a cheap carbon fibre kit from amazon, some peel ply and some spray paint, all other materials I had laying around the garage already and wanted to keep this project cheap as possible. The goal was to give the stock a negative comb, slightly flatten out the toe line, as well as shorten the fore end. I’ve never done any sort of work with carbon fibre or altering a stock so it was all new to me and figured this would be a fun learning project incase I feel up to building a complete stock one day.



First I lopped off a few inches of the fore end and used some JB weld marine putty to cap the end.IMG_5750.jpeg
Then I cut apart the butt end with a hacksaw and Dremel

Next I used some JB quick weld to attach things back together and filled with spray foam

Then put a bit of JB plastic weld on the bottom cause I ran out of the normal stuff.

I then sanded and smoothed everything out as best I could and got to the carbon fibre. Decided to just lay a half layer over the cut out and foam, figured doing a small part would be easier to start and see how it goes. I mixed up some resin and brushed it on, let it tack up a bit, then laid down the carbon. Wetted it out and covered in peel ply and wrapped with electrical tape. Waited 24hrs and removed the tape and peel ply, turned out ok, I sanded it down and prepared for the next full layer.IMG_5766.jpeg
 
Cleaned everything up and followed the same steps as last time, definitely a bit harder doing a full wrap, especially trying to get a clean looking joint, wasn’t really able to but didn’t really care because I know I’m painting it. IMG_5772.jpeg
Again waited 24 hours then removed tape, I was a little light on resin in a few spots but this is how it turned outIMG_5773.jpeg

On the third layer I overlapped the tape more and pulled at bit tighter to get more compression which I think helped. After the last layer I mixed up some resin one more time and did a top coat, more so just to see how it would turn out than anything else.

Here is a picture for comparison of factory stock vs changes I madeIMG_5788.jpeg

Next I shaped and sanded the fore end and gave the whole stock a sand with 320 grit sand paper. Wiped everything clean and sprayed a couple of light coats of adhesion promoter, then primed it with Rust-Oleum primer. Let it cure for a week then hit it with some Rust-Oleum multicoloured textured paint and some clear coat.

And here is the final product

It’s sitting in a tikka Superlite in 6.5 creedmoor

I picked up a .243 take off barrel that I’ll be chopping to 18” and installing on this one for a nice short little package for a truck gun, but that will wait till after hunting season. I definitely made lots of mistakes but learned a ton. I’m glad I started out with a small project and all in all I’m pretty happy with how it turned out. I might try vacuuming bagging the next project but still undecided. I’ve already ordered some better materials and will be doing a complete build for the next one.
 
Looks great. What would you say your total time / cost was?
Probably about $90 in stuff I had to buy, not including the spray foam, JB weld, or sandpaper I already had

Amazon carbon fibre kit was $35, peel ply from amazon was $21 and another $30 in spray paint. As far as time, it took a while but I was going slow and making mistakes and learning the whole time, if I did the same thing again I could probably do it in a week, the longest part is the cure times in between layers put down
 
Looks alright. I found though 55 inchLbs crushed my factory stock over time. It would lose torque the i realised the rear "bedding had collapsed a good 2 or 3mm
I also torque to 55 inch lbs, haven’t noticed any crush or my action screws loosen with nail polish on the threads but will take a note of that if accuracy changes

My action screws didn't loosen/move just they would continue to move at the same torque. When I removed it finally to clean shot of the shot I noticed the rear had collapsed. This is over 18 months of being kept at 55 inch pounds. It was worse on the bottom metal side by quite a bit.

Could you link up which carbon fiber kit and peel ply kit you ordered please? This looks like the exact route I need to go for modifying my factory stock.
