It Is Finished! 9mm AR-15 Carbine

Dear Barry,

I am clinging onto a 9mm carbine, possess several charged high-capacity ammunition feeding devices, love God, and can't say I'm bitter about it.

Now, you might be bitter. Check your shorts. Maybe Mrs. Obama starched them too much to the point of serious irritation. I read a couple of days ago that you've never fired a gun. Have the Secret Service take you to the range. You need a hobby. Shooting is good exercise, relieves stress, and is fun. Also, you might gain an edge in negotiations with manly heads of state such as Hugo Chavez and Vladimir Putin. Let's face it, Barry. You're a bit of a girly man. Even Joe, your gun-banning VP choice, has a shotgun for election-year photo ops.

Barry, I have to hang up now. Enjoy those last few days in Hyde Park. No, I won't accept that ambassadorship in Angola. Send the Rev. Jesse. Goodbye. ...

Yes, the UPS guy delivered the Rock River Arms 9mm top end plus a 9mm hammer. I had already installed the dedicated Hahn Precision magazine block in a Bushmaster lower receiver equipped with a Magpul CTR stock, 9mm carbine buffer and spring. The Hahn fit into the Bushmaster lower perfectly.

I cleaned rust preservative out of the top end and applied a bit of Tetra Gun oil and grease, put a spring on the 9mm hammer, installed it in the lower, mounted the top on the lower, and ventured out into a sunny, but extremely muddy, day.

I sighted in the carbine with some 115-grain JHPS at 50 yards. I didn't need to adjust elevation. The ARMS #40 rear required two clicks to the right. Then I tried a few 147-grain Hornady XTPs on top of 4.2 grains of Unique. Six rounds went into 1 1/8". The 115-grain Winchester USA ball ammo grouped between 3 to 4 inches as well as some reloads using 115-grain Remington JHPs and Winchester 231.

I ran 163 rounds through the carbine. There were four malfunctions during the first three magazines. The first round chambered would not eject once fired. Two of these malfunctions happened with some reloads using 88-grain JHPS I had left over after trading off a Walther PPK in .380. They haven't worked well in any 9mm pistol I've tried them in except for a Browning Hi-Power.

The remaining 88-grain stubbies fed through the carbine flawlessly. I blew up a couple of dozen hedge apples with them and some 115-grain JHPs in honor of Barry. All of the 20 and 32-round CProducts magazines locked the bolt and dropped free without fail.
