I have been looking for a carbine for my wife for HD. She liked the look of the Beretta CX4 Storm, plus it's made in Italy. I just figured that I get a pistol caliber upper receiver for the M4 instead. I don't want her to use a rifle round fearing for over penetration. I found this link http://www.model1sales.com/index.cfm?fuseaction=category.display&category_id=336 and was wondering if any of you have any comments on the performance and relaiability of these pistol caliber uppers.
Thanks for your comments.
