Putting a scope rail on polymer rifle

[MiCo]

Mounting a scope rail onto polymer...Do you just screw into the polymer or can it strip out? Are there any tricks?

my 15-22 has a polymer picitanny rail on it. i bought a 1 piece base and ring combo but i made sure the one piece rail had one long mounting surface instid of 2 points. that seamed to spread out the pressure more.

does that help? what are you putting the base on

Which rifle?

Wanted to put one on a Sub2000. I could put on a scope to shoot for a while and take off to fold or for open sights.

what kind of range are you shooting it. if anything i would mount a reddot not a scope.

I think a red dot would be best too. I just need to know how to attach the rail to the gun without stripping out holes that i would drill since the polymer is softer than metal.

Do a little homework on KTOG. There are several guys that have mounted quad-rail forends on theirs.

I would not recommend threading the polymer. You could easily strip it out, and be left with ugly holes in your rifle

The stripped out ugly holes are what i am worried about.

if you chose to mount into the polymer i would use a screw and nothing else threading is just asking for problems

is there clearance on the inside to use a steel plate to screw to?

Would like a small wood screw be best? The metal plate idea might work, if i can get it in straight.

Pretty cool, but i dont know if i want to add $100 to the gun. I could put that towards another

If there room a thread or nut plate is always the best idea keep in mine you can always counter sink into the receiver for more clearance as long as it thick enough.....and sheet metal screws are best they are much stronger than wood screws but find some thing with aggressive threads "like a drywall screw" but dont use drywall screws they are not strong enough

Thanks for all the advice so far.
