I have a friend who picked an original DISC rifle up and it did not come with the C tool. Is there anything that can be used in its place. Hecalled last night asking and I have never had an original one so, i am not sure how they fit. So no clue where to start with a make shift and I do not have the gun in front of me to look at.

I was hoping that maybe a reworked open end wrench, maybe? Or a line wrench?

All you need is a 7/16" open end wrench placed in the right spot.

Hopefully these pictures will indicate where to place the wrench.

I got one you can have.

Thanks SL for the photos and response.

Nimrodder, Thanks for the offer but it appears a open end wrench, will work as well. If not, I will PM you.

Thanks again

It is all in how you place the wrench under the secondary safety... When you put it under the safety you have to insure that the open end aligns with the cocking piece lug that needs to go up inside the wrench...

You'll figure it out...
