Even the U.S. government Springfield Armory found it a challenge to scope the M1 Garand for sniper rifle use, either drilling and tapping receivers for an expensive Griffin & Howe mount, as on the M1C, or installing threaded barrel blocks, as on the M1D.
Scopes, too, were fairly low-powered. A simpler solution to scoping a rack-grade M1 Garand today without permanently altering it is available from Amega Ranges. The company’s anodized aluminum Garand scout scope mount clamps around the rifle’s barrel, replacing the rear handguard with a 9-inch strip of Picatinny rail.
Any number of intermediate-eye-relief scopes or red dots can then be clamped on. The mount comes with clear instructions, Allen wrenches and all the parts necessary to do the job in just a few minutes, and the rifle can be returned to its original condition at any time. Price: $170.
