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:p. 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.

I think your premise is faulty.

With good thin jacketed .223 rounds you're going to get less penetration than JHP pistol ammo. The reason it works like that is as soon as the thin skinned .223 bullet hits anything, even sheetrock, it starts falling apart. Pistol cal JHPs tend to clog up and behave like FMJ in similar circumstances.

Aonther factor is power: .223 may be a weak rifle cartridge but it's tremendously better at stopping men than any reasonable pistol cartridge.

Lastly, I've yet to see a pistol cal AR that was nearly as reliable as a .223 rifle. the conversions all seem to have problems of one sort or another.

Brian,

Thanks! That answer was exactly what I was looking for. So my next question is, what type of .223 ammo/brand should I get then for HD?

hornady tap. availible in multiple flavors(grain weights) and everybody else seems to prefer this stuff.

hornady

That seems to be a very good choice. It's what our local PD use and most the guys they shoot with rifles seem to drop from 1 round.
