One of the basic differences between AR's and bolt guns is that no special skills are required to assemble a 1/2moa rifle. You simply purchase good components and follow simple instructions to assemble, no special tools are required, no special skills. That can't be done with a bolt gun, chambers need reaming, headspace needs setting, actions need bedding or you spend more money on a chassis or stock that doesn't require bedding, A good AR based gun can and will provide all the accuracy you NEED, are they as accurate or more accurate than a bolt gun can be.....NO. But they are accurate enough, reliable enough, and YOU can completely disassemble it and reassemble it. Using one to hit a 2moa target at 1000yds has been done, so a properly built one can do it,...........can you?  They have been described as being the Chevy small block of the gun world,....parts are easy to find, easy to replace, easy to upgrade, and easy to modify. Trapr |

 2 MOA? at 1000 yards? Yikes! Think about that. Sounds like numbers from the run fast shoot fast boys. Work buddy just back from a 600 yard F class match.. Asked him how many AR based guns he saw on the line. He said, "None."  I don't think 2 MOA gun would stay on the 600 yard target much less the 1000 yard target. No headspace Checking? You don't use a go/no go gauge?

I thought so! I found one of our range guys doing the same thing.  He didn't even know what go no/go gauge set was much less what to do with it.. |

Some of the higher end AR barrels come with matching bolts. Not to be confused with the bolt carrier. Headspace is not adjustable in an AR, but you can try bolts from different manufacturers to see if you can tighten headspace a mite. Do remember that you are dealing with a semi-auto, and that the rules are different in some areas. At least two of the ARs I've had benched out to 200 yards right around 1/2 MOA. I know David Tubb often competes with an AR at long range, but have no specifics on what sort of results he has been getting.

Axe, the 2moa requirement is for the LR matches I shoot, they are refered to as "hike and shoot" matches. You have to carry whatever you think you'll need for the match all weekend long. So yes 2moa targets, no firing line, no standard prone position, no un realistic overly large fancy bipods, or shooting mats to lay on, just rock, cactus, trees, and such.
I know gas guns aren't popular in F-class, but then bolt guns aren't popular in 3 gun either, but people still use them. Luckily there are enough shooting sports out there for everyone to find one they like, or want to try. It doesn't make one better than the other just different, just like guns.

"Hike and Shoot" sounds like fun... Would make for a drastic equipment revision. The 18-22 pound F Class rifle would get old quick!

As previously said David Tubb used to shoot AR10's in completion. He used to win, a lot. He then designed his own bolt gun built by McMillan, Tubb 2K.
My Larue OBR will hold .5 MOA or better with no problem out past 1K.

Shoot F/TR then you can build a gun that has more purpose than just belly bench rest. I don't use gauges when assembling AR's either.... Of the thousands of M16's I performed LTI's on, I only ever had one almost fail with too much headspace. I swapped the bolt with another rifle and they both passed. |

Yes, a 18-20 pound rifle ain't much fun, I shot my heavy 300 win mag for a year, and then decided to save powder, and weight by going with a lighter gun in 260.
They are fun matches though, and very useful as you can relate them to hunting, and hunting type conditions.
You have limited time to locate, range, get a suitable shooting position, and fire. One round at each target, figure wind speed, and direction, and sometimes move shooting position. Typically five minute time limits, and 6 targets per shooting location.
I shoot F class locally just help with staying proficient, as most of these matches occur in western states.
