The new toy is here
And ready to hit the range. Bought this AR-10 (308) at an auction last weekend. Checked everything out and it appears to be unfired and everything is functioning as it should. Installed a Burris 3-9X Fullfield II scope I had laying around, cleaned it inside and out.
I have 4 Magpul magazines loaded up and ready to sight it in and see how she performs. I really like the heavy barrel on this rifle. It holds much better than my AR-15 (223/5.56)

You mentioned in your thread that your trigger has a bit of creep - pretty standard for mil-spec triggers.
If you want to take out that creep - or at least a bunch of it, drop by the hardware store and pick up a 1/4"x28 x 1" socket cap screw (3/4" if they have it), and a 1/4"x28 x 1/2" plug/set screw. You might not need the 1" cap screw, but if you do, it's worth buying to avoid the extra trip back (it's a spare though, so you don't have to modify the original).
Unload the rifle, remove the pistol grip (be careful not to lose the pivot pin detent and spring or the safety selector spring and detent). Engage the safety (safety on), then screw the plug screw into the pistol grip screw hole as far as it'll go. It'll raise the trigger to touch the safety selector - screw it JUST TIGHT ENOUGH to let the safety selector operate freely. Double check function at this point to make sure the disconnector will still reset when the trigger is relaxed. USUALLY it will, but if it does not, you need to back out the screw slightly until it will reset. Once that point is found, use some blue (or purple) loctite to keep it in place. Then reinstall the pistol grip with the shortened cap screw. If there's still a bit of creep beyond your liking and you have plenty of reset movement to reset the disconnector, you can grind a bit of a relief in the top of the trigger to give a bit more clearance for the selector.

NoMercy - your instructions worked like a charm on my Stag Arms AR-15. But for some reason it did not on the Palmento Arms Ptac lower. Seems like the screw hole in the Ptac did not go as deep into the receiver as the Stag's hole. The set screw bottomed out before reaching the point were it would bind up the movement of the safety lever!

Got to get out and do some serious shooting with it. My initial outing I had installed some old rings I had. I knew one of the screw holes was stripped but I figured the other 3 would hold until I got new ones. Wrong. I ended up getting a new set but they were just a tad too low so I got a picatinny rail riser (low). Put the scope on that and mounted the whole works on the flat top. I also got a set of flip up sights for it In case I the scope becomes wrecked.
I'll sight in the iron sights (actually aluminum) then the scope.
