At SHOT Show Industry Day at the Range I was excited to see Mimic Firearms were attending and as soon as I finished covering the First Shot of SHOT and catching up with Christian Craighead at the Steyr lane I headed straight to Mimic to check out their Speed9 carbine.The Speed9 features an interesting proprietary magazine set up.The magazine has two 30-round double stack magazines orientated back to back.This gives you 60 rounds on the weapon in a form factor and size not too different to a 30-round STANAG magazine.
