Description
9mm. Bufferless. Side-Charging. AR.
What more could you ask for? The engineering update the AR should’ve received decades ago is finally here, and we’re excited: This AR9 upper assembly features an entirely internal, self-contained bolt carrier group and recoil system that ditches the external buffer — no more buffer tube required — and it ditches the standard charging handle in favor of a slick side-charging unit.
Bufferless Upper Includes Sealed End Plate
Included with this upper is a unique, sealed end plate that threads into any standard buffer tube housing’s threads — including our dedicated AR9 80% lowers, and all other retail-bought 9mm AR lowers.
The end plate features a Picatinny rail for attaching your choice of folding stock adapter.
