The Matador Arms Montgo-9 Complete 9mm Upper fits most AR-15/AR-9 Lowers. This upper features a 5.5-inch barrel crafted from 4140 steel with a black nitride finish. The billet aluminum upper receiver is hardcoat anodized to maximize its strength and durability.

Compatible with any AR-15* and/or AR-9 lower (magazines for Glock® 17 & 19 OR Sig Sauer P320), the Montgo-9 gives shooters endless build possibilities while being compact and versatile.

*AR-15 lowers will require the MagX adapter (or similar) to accept 9mm pistol magazines. We recommend using a standard AR-15/AR-9 trigger system, and not binary or FRT triggers. We do not recommend running the Montgo-9 in full auto.
