9mm AR - Pro's and Con's from Owners??

[shooter521]

why would you want a 9mm in a gun that size, is there a point to it?

To recap:
• Cheaper to shoot than .223
• Allows you to shoot your AR at ranges that forbid "high powered rifles"
• Much fun at steel plate matches
• Good for introducing new folks to the AR (less blast and noise than .223)
• Excellent for SBR and/or suppressed applications
• Allows stocking a single type of ammo for both carbine & handgun

Excellent bullet point for Pro's! You should be in firearm sales!

While I own a couple pistol caliber carbines, and while I agree with all the points laid out by shooter521, let me toss out a bit of a reality check that shows, at least in part, an opposing view.

• A 9mm carbine is a lousy as a varmint rifle
• A 9mm carbine is a lousy hunting rifle
• A 9mm carbine is not as effective as a 5.56 QCB/home defense gun, and 9mm rounds have a greater chance of over penetration and also will penetrate more sheetrock walls than 5.56 rounds.

In reality, a 9mm carbine is an answer to a question that nobody asked.

But if you want to practice with your AR at a lower price and have a similar feel for recoil (something not possible with a 22lr conversion) then the 9mm carbines provide a good option. It provides all the benefits mentioned by shooter521, even if it is not an ideal gun for most things.
