The M1D is the renowned sniper rifle variant of the M1 Garand and can now be built to its original standards. These Criterion barrels feature a scope mount block that is precision-machined from billet and installed in house; superior to the low quality cast replicas that have limited the market. For an accurate reproduction, we are also offering shortened handguards to complete your M1D build.All M1 Garand barrels are hand lapped and held to match grade tolerances. Each barrel is .010 short chambered and should be properly headspaced by a qualified gunsmith.
