About
What it is, and why it matters
The Foxtrot Mike FM9H Hybrid is a 9mm AR-pattern pistol-caliber carbine that feeds from Glock-pattern magazines and is distinguished by its polymer 'Hybrid' lower receiver, whose pistol grip doubles as a reserve magazine well holding a spare Glock magazine released by a side button. It runs a straight blowback action from billet aircraft-aluminum upper receivers, with a 16-inch 41V50 barrel finished in black nitride, a 1:10 twist, and a 1/2x36 threaded muzzle capped with a Micro Blast Diffuser. The rifle uses a 15-inch M-LOK free-float handguard, a USGI mil-spec trigger, an FM Products ambidextrous safety, and a four-position front charging handle.
Offered across braced-pistol and 16-inch carbine configurations with front- or rear-charging uppers; the defining feature is the reserve-magazine grip that stores a loaded spare while a magazine is seated in the primary magwell. The 27-round figure reflects the common Glock-pattern extended magazine shipped with the rifle.
