If you don't need a complete AR-15 carbine and already have a mil-spec lower receiver, then an Olympic Arms WSSM conversion unit is all you need to shoot WSSM .223, .243 or .25.
No modifications to the lower receiver and no tools are needed to install the unit. Just put the upper on your complete lower and you're good to go.
These kits use custom AR-15 magazines designed to hold the Winchester Super Short Magnum cartridges. The magazines are all metal for rugged durability.
These caliber conversion units are fully assembled, headspaced and test-fired.
