The Trijicon ACOG 3.5x35 Scope w/ TA51 Mount with the TA11H and TA11H-G reticle are designed for 16" barrels. It will still work with your 11.5" barrel, however, the holds and hashmarks may not be accurate to your point of impact after zeroing.
The Trijicon ACOG 3.5x35 Scope w/ TA51 Mount sits at an absolute co-witness height of 1.4" (centerline). This means it would align with traditional AR15 iron sights. However, this is a magnified optic, you won't be able to use your iron sights with the optic as they will be out of focus.

You could mount the Trijicon ACOG 3.5x35 Scope model TA11H to an M1 Garand using a compatible scope mount. Even though the reticle is designed for .308 you could use it for 30-06.
