Yes the Amend2 mags are the length of a 20 round AR-15 mag whereas ASC, E-L and CPD ten round mags are shorter.
Quick measuring a 20 round 5.56/223 mag 5 long at spine tapering to 4 3/8 at front.
ASC ten round 6.5 Grendel mag 3 3/4 at spine 3 1/4 at the front
ASC 15 round 6.5 Grendel mag is exactly the same size as aluminum 20 round 5.56/223 mag. The body of the ASC mag is stainless steel.
I dont have an Amend2 to photo but this will give you an idea of the size difference.
