Geissele ICM 8rnd Stainless Steel Black Magazine 05-3230 is purpose-built and designed from the ground up to reliably feed 6mm ARC, so it doesn't inherit the compromises that come with a magazine adapted from a different case profile. This Geissele ICM magazine features a one-piece 410 stainless steel body, laser welded rather than spot welded for real long-term durability, finished in black nitride for corrosion resistance. A stainless steel square spring drives feeding, backed by an anti-tilt follower that keeps the stack aligned under recoil, and cartridge-optimized feed lips guide each round into place to cut down on jams. Compatible with 6mm ARC, 22 ARC, and 6.5 Grendel, this 6.5 Grendel Magazine covers three cartridges most magazines aren't specifically tuned for. At 3.5" overall length and an 8-round capacity, this Geissele 6mm ARC magazine suits jurisdictions with magazine-capacity restrictions or shooters building compact, balance-preserving setups for short-barrel rifles and pistols.
