I have been a member of AR-15.com for three years, and purchased an AR-10 carbine the day after "Our Glorious Leader" was elected. I have installed a FF tube on it and recently treated the barrel with Ultra Bore Coat. My rifle shoots 1-1.5 MOA as is, and I'm about to try Hornady's new Superformance ammo, to assess whether it gives any worthwhile boost in velocity. I will post on this and the effectiveness of the UBC as soon as I have this data. I am interested in upgrading to a short magnum caliber. I look forward to reading and contributing to the forum.
UltraStealth, welcome to AR-10T, hope you will enjoy what we have to offer.
Another Carbine owner, well if you need any help with accessories, let me know as I have one as well....
You wrote...the day after "Our Glorious Leader" was elected....NOW that is funny......LOL :lol:
I have to say I am not to familiar with the process you spoke of, but that is not saying much...LOL, will be interested in hearing how it works....I myself have pulled down under 1"moa with mine so it is very possible...
Again, Welcome and thanks for joining...

I'll tell you something interesting that happened to me with regard to accuracy. I was disappointed after I installed the FF tube, as the accuracy didn't improve at all, still around 2 MOA. I had neglected to install a longer dust cover hinge pin, and the dust cover came loose. I had to remove the FF tube and barrel nut to install a longer hinge pin. After re-installing the FF tube, my accuracy was now 1 MOA. I don't understand why it changed (though I was very happy about it), unless the amount of torque on the barrel nut plays some part in the barrel vibration.
What you just have happen is the soft aluminum receicer just flattened and squired itself up a little. Thats what I sale the bolt squireing tooling to Brownells for. Midway coppied the tooling and they are saleing an unlicened product and do not own the design or rights to the tooling and that will catch up with them. The AMU puts the barrels on at 50lbs and throwes the uppers away at barrel changes. I designed this tool to get rid of the heavy uneven plated spots that were causing walkers in the rapid fire stages of the national match course. Brownells is the only company that I have ever sold or OK the MFG of this tool.MSH
Its brownells part no 080-000-182 AR-15 Lapping Tool. Use a 3/8 drill and 120 grit cloves valve grinding compound to squire the receiver face inline with the receiver bore. When the face is white your done. Real simple it keeps the students from screwing up.MSH
The tool only works on the 15 because the receiver size is much bigger on the 10. I haven't sold any of the 10 tools yet. Brownells wasen't interested because of the lack of A10 intrest. The marines have gotten several of them for their armors. I will be making up another batch of them soon.MSH
