Thread: DIY Carbon Fiber Rifle Stock

Nice clean lines and great finish... Well done mate!

What is the barrel channel usually filled with in the available carbon stocks. I'm not sure what it is in my Ken Henderson.

Not sure, I have heard some fill the fore-end with foam and layup a layer of fibreglass on top of it. Perhaps STUG could advise on that?

I made a mould of the barrel channel and glued it in place in the stock. Then drilled a small hole at each end of barrel channel. Then poured in the PU foam in through one hole and blocked that hole with tape while allowing the excess to flow out the other hole after filling void. Epoxied over holes to seal them afterwards. Butt also filled with PU foam - very light and adds stiffness. Very little PU foam required as the expansion is incredible after mixing the 2 parts!

I would guess Polyurethane foam, that's what I used for mine, and I think Stug used that too.

Good work bro.

Very well written I could never make one but enjoyed reading about it ��

Thanks, I am glad you enjoyed the read.

I use Sika Boom expanding foam in the stock to deaden the hollow sound a bit. I cast a barrel channel liner from carbon fibre and epoxy it in the foreend when I am bedding them action and doing the edges of the barrel channel.

Thanks, I think I will give that a try on the next one.

Great write up and brilliant result. I have successfully put this project off myself for around 5 years so far.
Been a long while since I have played polyester resins.

Yeah, I had been thinking about doing it for a while, but the project as a whole seemed quite daunting.

The hard part was finding out how to do it. There was very little out there about how to make a stock. That's why I have posted my experiences, to help others wanting to give it a go.

Do you have any pictures of the tabs for the butt joint?

You could probably save a fair bit of weight by vacum bagging it.... then it's just a small step to a one piece stock with a latex bladder

@Chilli_Dog No I didn't get any photos of tabs, but will take more detailed pictures when I build the carbon fibre stock.

Would love to try vacuum bag, but unfortunately I don't have a vacuum pump.
