I mounted up a 4.5x14 Leupold on mine, and found it would keep factory match ammo well under an inch at 100 yards, when I did my part. :D

The downside is, it had more than a few failures to eject. The commercial ammo did it occasionally - the Lake City ball ammo I tried did it about every other shot :cuss:

Prior to today's session, it had about 30 rounds through it since the last cleaning. Anyone care to speculate this is just a cleaning issue, or should I check something else?

Thanks!
 
AR-10s are more finicky than ARs, but failing every other shot with Lake City ammo...something is wrong.

Pull out your bolt and strip it. Make sure the ejector is not binding. Check your chamber for toolmarks. Check your headspace and make sure that you're not cramming over-long rounds into a short chamber. Make sure that your gas key is tightened down.

AR10(T) models have a very tight match chamber, but should still be very reliable with quality commercial .308 (eg Federal GM Match.)

If it's not a T mode, then something is installed backwards!!!

If it is a T, then something is still wrong. Check headspace, chamber for roughness, and lube and bolt/gas-key.
 
I've found that the bolt must be wet in an AR.

I use Break Free liberally. If you hold the bolt carrier group with the bolt retracted and flick your arm down, the bolt should move to the forward position from just that inertia alone. If the bolt binds in the carrier group things can go wrong.
 
I cannot wait for good, reliable aftermarket magazines. The factory ones are hit and miss. Sure does shoot good though, doesn't it? :)
 
also, if you haven't been using a chamber brush made for the job as part of the regular cleaning regimin.
 
:evil: for anyone offended by Skunky's outburst, please know that his remark is much more diplomatic than what he wrote when I informed him by IM that I'd bought the AR-10 - which he of course, can't buy in CA. :neener:
 
I now have several 20 rd mags on order, too, and a photo :evil:

That is a 100 yard group, 4 out of 5 in 5/8", and I shot another without a flyer that was about 7/8". The load was Win Supreme Competitions, with 168 Nosler match bullets. A little trigger tuning and some handloading may make things REAL interesting.

I gave it a good cleaning last night, and everything seems in good order. I'll give it a try again in a few days to see how it runs. :)

Oh Skunky....hmmm...if you ever make it to a free state, and introduce me to Betty, I'll let you shoot it. :evil:

Yeah...Art's Grammaw would ban me! :eek:

Betty? Twoblink's M1A or the former moderator? I never met either :eek:
 
I was having problems with FTE's on my AR-10 and sent it back to the factory. They said they reamed the chamber a little deeper and Polished (?) it. At any rate, no problems since. I agree with the reliable magazine issue. They can sure make one like the AR-15 magazine with a raceway in the rear and a standard-type follower instead of that jammomatic mechanism they have invented there.
 
yeah, you can get them with a lighter weight barrel, check Armalite's website. You can get them chambered in .243, for that matter. This one is a little unusual I guess, as most of the carbines don't have heavy stainless barrels. Of course, that heavy stiff barrel is probably one reason why it's so accurate :)
 
With the 20" light profile barrel it feels like an M-16A2. I would imagine the light barreled carbine would be as handy as a CAR-15. You can even get collapsing stocks for them.
