Tips for accurizing an ar...

[William Suter]

If you want an accurate one, put on a quality barrel with a quality trigger and square the face of the receiver. I have built quite a few that will consistently shoot .5 MOA or better groups. You must use quality parts though if you want that.

That was three of the main points made on the Accurate Shooter article. A heavy duty quality upper was another. Mil spec had to much flex.

All not worth the bs here is PA...but if you have the time and money...go for it.

I use the BCM stripped uppers. You actually have to heat them up to get the barrel in. It is a very tight fit.

I was of the impression heat makes metal expand and cold makes it contract.
I’ve put parts in the deep freeze before to get them to fit easier .

Heat expands. Cold contracts. Freeze the barrel, heat the receiver.

Tip #1 Bolt guns and AR's require different shooting/gun handling techniques. The typical higher optics on an AR will alter the trajectory path of bullets, requiring zeroing corrections. The old scope on a carry handle setup really messed up bolt gun guys, trying to shoot mid range targets with a 100 yard zero.

I don't really understand your comment. Increasing height over bore flattens trajectory. And your scope should be zeroed to whatever rifle your shooting.

I do not believe that is mechanically correct. In order to compensate for the higher scope height above bore the bullet has to rise at a steeper angle which means that while the zero may appear flatter at distance, the mid-range trajectory will actually be higher rather than flatter.

While scope height may affect zeroing and your POI at various ranges, it will not affect your ability to shoot a small group at a given range, which I believe is what we're discussing here.

If you have the hornady ap, alter you sight height from min to max watch what it does. I first found this out when competition steel banging rifles were the rage and they had special aluminum mounts like 4" over bore.

1 inch groups are more than acceptable for hunting.

Leave your rear rest, and bi pod at home someday. Forget sitting at a bench.

See how your groups are at 200 yards.

Compare your most accurate loads, and your worst ammo you have ever fired from the rifle.

You may be surprised by the results.

More accuracy never hurts.
