SCRUNGLR Bullpup Can Cannon Lower

about

The SCRUNGLR is a lower reciever that converts an F5 Products can cannon upper reciever into a compact shoulder fired bullpup launcher.

This lower was originally designed to host a 50 bmg upper reciever, then redesigned to fit the can cannon.

The lower can be assembled with M5 bolts and a standard AR15 FCG. A dual transfer bar will need to be formed with 3mm round tube or coat hangar wire.

This lower can be built with a buffer tube to return the bolt or left open on the back to allow manual return.

This lower is not compatible with the variant of the can cannon with a lower picatinny rail.

This lower is compatible with the 40mm subcaliber barrel for the Can Cannon.

Two ar15 grips are used to assemble the lower, with one mounted backwards and the main grip angled forward, identical to the factoty configuration of the M82A2.

The original 50 BMG version will also be released soon with different features.
There is no magazine well on the 50 bmg, the grip and stock are further forward, and the trigger transfer bar is internal. It will not be parts compatible. Do not use this lower on an upper reciever that is not a can cannon, the barrel of the can cannon holds the trigger in.
