Amend2 builds this magazine (part no. 65GRENDBLK10) for AR-15/M4/M16 platform rifles chambered in 6.5 Grendel/6mm ARC, a cartridge whose longer, heavier bullets require different internal geometry than a standard 5.56 magazine. Made of an advanced polymer material, it’s a light, durable alternative to trying to force-feed a Grendel upper with a standard M4-pattern magazine, holding a reduced 10-round capacity. At 6.65 inches overall and finished in black, it’s built specifically around the Grendel/ARC case shape rather than adapted from a 5.56 body. For Amend2 owners running a 6.5 Grendel or 6mm ARC upper, this AR-15 magazine is a purpose-built fit.
