A great option as an upper for a home defense, truck, or ranch gun.

I am selling my Wolf 5.56" piston upper with a 12.5" barrel with a 1/7 twist rate. This uses a short-stroke, non-adjustable gas piston. 

It is a clone of the Taiwanese T91 service rifle and will fit on a standard AR-15 lower. Included also is a Geissele Super 42 Spring with H3 buffer. This buffer system is necessary for this upper to run reliably. 

Also included is a Primary Arms 2.5x Prism Optic with an etched, illuminated reticle.

While I intended to sell this as a complete package, I am willing to sell the upper and optic separately. The options are as follows:

Wolf T91 upper w/Geissele spring kit: $650

Primary Arms 2.5x Prism Optic: $200

Looking for a cash sale.
