The Spike’s Tactical ST9G solves the magazine compatibility challenge of AR-9 builds by accepting Glock magazines, giving you access to inexpensive, readily available mags that work across Glock pistols and PCC platforms. This lower works exceptionally well for home defense carbines and competition builds where you want magazine commonality between your pistol and carbine. What sets the ST9G apart is the forged 7075 T6 construction instead of billet – you get mil-spec strength at a lower price point, and the oversized magazine release makes reloads faster under stress or with gloves.
Note: When using a standard buffer, use Spike’s 9mm spacer with it, or use a dedicated 9mm buffer by itself.
