View Full Version : Devcon & HS Precision FN SPR stock
Does anyone have any experience using devcon 10110 with the HS Precision stock that comes on an original FNSPR?
Is the Devcon literally putty or does it pour in etc etc...
How well does it bond to the HS Stock matieral?
I did some research today at Grainger and found that 10210 is the same hardness as 10110 and has more of a pudding consistency. It will pour much like the MatchGrade Bedding Compound.
You might consider the gray colored Marine-Tex also, if you can't find the Devcon you're looking for.
I actually found the 10210 5 miles up the road for $40.00. I will pick it up Monday and give it a try.
I don't know about the FN action but I recently bedded my 700 SPS-T in an HS 700VS take off stock. Devcon is easy to work with and gets you a good solid rock bedding. Marine Tex from what I've heard is very similiar. I will probably only use Devcon as I had good luck bedding my rifle.
The 10110 is a 2 part mix that mixes 2.5 to 1 volume. I used a set of measuring spoons from the dollar store and used 2.5 Tablespoons to 1 of the hardener. The dark part of it is real putty like and you can fill up .5 easily enough. The hardener is the white portion and viscous. It's almost liquid like if you can understand.
I ended up bedding my rifle 4 times before finally getting it right. Yes I said 4 times. I first tried with my Hogue stock that the rifle came with and it turned out miserable as I didn't have enough releasing agent on the rifle. Kiwi Neutral worked well once I had enough applied.
Once I started bedding my HS stock I had too much masking tape around the barrel to raise it up so it the ejection port was flush with both stock and action. On the 4th atempt I set the action slightly lower and in my case worked out perfect. The action screws would finally engage.
Make sure you rough up your bedding areas for mechanical locks. I used a Dremel and made little holes for the putty to work its way into. Popsicle sticks work awesome for mixing and applying the Devcon. Use a ton of Kiwi and buff it out. Don't have too little and get yourself a unigun. Play dough worked well for damming up all the areas of the action and stock that I didn't want bedding in. I used "Stock Inletting Screws" from Midway to free float my action to create a stress free bed.
If you decide to use the 2.5 to 1 tablespoon amounts you should have quite a bit of putty left over. I had quite a bit so I textured some wood dowels and plywood that I was working on. The HS stocks work great to adhere to if you plan on texturing but the Devcon can get extremely aggressive. I had a bunch of little cuts on my hands so I knocked it down with scotch brite and blew it off with a blow gun.
All in all it is nerve wrecking the first time. But as long as you mask off areas such as the front and sides of your recoil lug, apply enough releaser agent, play dough everything you can think of, it works out nicely. Oh and after about 3.5-4 hours (I think thats how long I waited, check your excess for hardness, if you can see a fingernail imprint wait longer) pull your action out and trim up the excess putty for ease of clean up. WD40 and Qtips work good for oozing but I scrapped my excess off with popscicle sticks first.
I know this is alot to take in and I'm no expert but these are the tips I've followed. SH.com has an entire thread on bedding with pics and is a great resource. As with all little DIY projects your mileage will vary but good luck!
Thanks for the tips. I used oven-bake modeling clay to damn up the stock and action along with some automotive masking tape. Everything is ready, but darn it... I didnt make it up to the supplier to get my devcon today.
I also bought some Duracoat and some truck bed liner to refinsh the stock after the bedding.
Doesn't FN use Marine Tex to bed their stocks? Probably next to no difference but I believe thats OEM for FN and McMillan
