Dual strike rumors

A couple of days ago at a nerf war, one of my freinds told me that the smart ar in the dual strike was extremley similar to the ones in the sweet revenge in the matter that you can take off the barrels to access the smart ar and in theory brass the barrel and still have a smart ar. And today I got to testing this and I can confirm these rumors are indead true.
