I want to be assured, these mags will function in my AM15 Expert Answer

As long as the rifle is chambered in .458 SOCOM, these will work with the AM-15 rifle.

So we should be able to put 30 rds of 300 AAC in this also??? Expert Answer

No, unfortuantely parts have been modified to work better with the 458 SOCOM round. The manufacturer has stated that the magazine will not run .223/5.56 reliably. This should be expected to extend to the 300 AAC.

Helpful Positive Review High Quality Magazine by PoP Engine, February 15, 2021
This is a high quality magazine that loads well and feeds well. Comes already notched to feed .458 SOCOM ammo. These are well worth the price and much better than the plastic style magazines in my opinion. I am very pleased with this product.
