Allen Engineering AEM5 22Cal

The AEM5 is the direct fit replacement for your MK12 SPR. The AEM5 attaches to the weapon via a mount(not included) and a collar that goes over the barrel for alignment. The suppressor mounts via threads on the outside of the mount centering on the adapter fitting. A 20 degree taper on the adapter locks the silencer onto the barrel.
