Thread: Optilock Screws

Hey guys,

Just bought a nice Sako 75 Hunter (walnut blue) in 223 and the optilock ring screws are pretty shagged (last owner).

Also noticed a small but long crack in the for end.

Any suggestions how to repair and where to find new screws?

Do any old screws fit from other rings?

Cheers,

F.

Apparently screws are easily replaced at somewhere like SteelMaster... I had the same issue. Tom Curtis sussed me a replacement set of screws when he was there on another mission and don't think he even bothered charging me the dollar or so they cost him

Pretty certain gunworks stocks them..

Will have a look cheers.

$10 a screw.... dark they are expensive!

Steel master it is.

Anyone know about wood repairs?

Regarding the forend crack. Method of repair depends on which direction the crack is running and how deep it is.

I've found polyurethane glue to be easy to use in cracks and it is very strong. Or epoxy which is a two part mix (and it is better if the two parts are mixed precisely. Mix in some sawdust from the piece of wood being glued or some other wood of the same colour to make a repair almost invisible, however, epoxy does tend to dry darker, so best to test first for colour.

The crack runs down from the foreend in line with the barrel and is about 2” long

I presume its a wood stock ?
Use the super strength epoxy that stays liquid and runny for a long time.
Smear it on then gently spring the wood somehow to let the glue suck into the crack.
Flex it in and out a lot of times but gently.
Wipe off what you can afterwards and tape it tightly together so the crack is closed while the glue sets.
Leave it to stand overnight in some way so the glue will seep in rather than out.
After 48 hr try and peel/flake off any from the outside, sand with 600 then 1200 on the end of a pencil eraser.
Put on linseed or other stock oil to fix surface and fill in the last of the crack.
I had this at the tip of my .303 foreend and 20 years later its still good.

If its a plastic stock there are special plastic glues where you write on with a pen then spot glue but I'm not sure how to get it into a crack.

Yep, pretty well the right approach. If the crack cant be opened up I drill several tiny holes down into the crack and force the epoxy in that way. Just dont drill right through your stock though.
