M1 garand scope mounting

I know I have seen the mounts before just not seeing any of them now good luck I am sure if you contact the cmp they would have more information on it and maybe who makes it if they don't have em for sale or someone else here has more information .
 
Ultimak makes a mount that replaces the upper handguard. You retain the ability to use enbloc clips, but have to use a long eye relief scope...
