Decent price too.  CNCGuns charges $412 for their finished AR-45 lower.

Those look pretty decent. The gas system would prevent me from getting one though, as it limits you to jacketed bullets only. 99% of my shooting is with cast, blowback is better for that.

16" barrel I assume? Can you chono some loads and post the velocity? I'm very interested in what the 10mm can do in a longer barrel like that.

[REDLINE]

Me too.  Very curious about the velocity.

This can give you an approximate answer. You can interpolate a result from this.

I have never owned a AR rifle but I am considering getting the Olympic Arms K10 Carbine 10mm to compliment my 10mm pistols. Thinking of the Flat Top Rail and Free Float Smooth Tube as a start for this package.

I would be interested in feed back on (do' and don't), (pro's & Con's) for this particular rifle in the 10mm pistol caliber.

Does anyone have this AR arangement? If yes, do you like it and does it function well?

Do the NEW Olympic Arms 10mm magazines work well without issues?

Has anyone had issues dealing with J&S Gun Parts?

Thanks in advance to those who will answer my particular questions

I have my "HouseGun" (See Above) and I love it. The bullets scream out of the barrel (165gr Double Tap) at nearly 1700 fps for an Energy of over 1000 ftp. I am currently using an Olympic Arms blowback upper but plan on upgrading to a BB left handed gas unit as I am left handed and with the Oly upper the cases eject backward just past my ear.

As it is blowback, the upper needs breaking in and wants to be run wet with a heavy buffer and full power springs. The magazines are GG mags which I load to 35 rounds. I pinched the feedlips in with a vice till the cartridges directly face the chamber.  It is the perfect Urban carbine, fulfilling the idea Jeff Cooper had for a "Thumper". Mounted with a 1.5-4 power scope the weapon is lightweight, powerful and utterly reliable. With six mags on your belt and one in the gun, you can carry 245 rounds on your person. Add a light and it is perfect for those needing something to drive off looters. As the weapon is the same caliber as your sidearm, if your sticks run low, you can shift ammo from your spare pistol mags to your rifle. If either breaks (pistol or Rifle) then the surviving weapon is used till the other is repaired without walking around with useless ammo weight.

The 10mm totally changes personality as it increases energy. Instead of a powerful pistol round, it acts like a rifle round, penetrating cover with authority, punching through instead of glancing off. Cars, doors, even at range become transparent. For the One Caliber man, this is the way to go. The 45 ACP, while a good round, does not display this behavior in a Tommy gun or an UZI because it never gets the Energy. The 357 Magnum in a lever gun, loaded correctly has this same "personality change" as the 125 grain bullets go from 1400fps out of a revolver to 2000fps out of a Marlin lever gun.

As soon as I can, I am going to get some 200gr FMJ Underwood and chronograph it out of my AR. I also have a supply of Silvertips that I would like to push down the barrel to see what I can get them up to. If it is even close to 1700 with AA#7 or AA#9 or 800x then a screaming Silvertip in both pistol and rifle would be my favorite.

Goldbead, you have just illustrated why I think the 10mm is the ultimate cartridge for a the one caliber man.  It is a heavy duty auto-pistol round, medium duty revolver round, and excellent sub-gun round.  There is very little in North America that can't be dealt with by a carbine sized 10mm.

That's me.  One caliber for each major platform type.  Handgun = 10mm Auto.  Bolt Action Rifle = 7mm Weatherby Magnum (not yet, but that's the future plan).  Black Rifle = 358 Winchester (not yet, but that's the future plan).  Shotgun = 12ga.  Then there's rimfire, but I'm leaving that out of it.

This is a valid point for the 10mm.  One of my favorite issue weapons was the H&K MP-5/10 10mm sub-gun.  Great for clearing a house, perfect size, almost ZERO recoil.  But it would easily reach out to 100 yards using our Federal 190 grain JHP duty ammo.  The Thompson (we have two 1928's in the vault) is very fun to shoot, but I liked the MP-5/10 better.  Alas, mine was recalled for maintenance and I was issued an M-4 (not that I'm complaining).
