About fed up with my AR- Accuracy issues

[Playa]

You're not shooting progressive twist, by chance?

I don’t even know what that is

[Tazman70]

Longer barrel is like longer draw length on a bow. It will increase FPS and therefore result in tighter group. Just look at how the 20" Garand M1 performs compare to modern day 16" AR-10.

It affects FPS, wouldn't say accuracy.

That is entirely incorrect. It is based on the quality of the barrel. I have seen a 16” AR10 shoot sub MOA out to 900 and while I can site numerous examples I’ll save myself from typing.

Length increases FPS as stated earlier but has no real bearing on accuracy. Every gun is different even when built with the same components.

Correct.

The only exception is with open sights. Then the longer barrel will shoot more accurately due to the increased sight radius......nothing to do with the barrel or bullet.

2-3" groups from a "budget" AR15, with a cheap plastic hand guard, sounds pretty darn good to me. You don't have to spend a fortune to get an accurate gun, but a factory Anderson "mil-spec" firearm will most likely never give you sub moa results. If it does... it's a unicorn, not the norm. If you want a tack driver, invest in a better barrel and a free float hand guard. That's why so many people build ARs instead of buying factory ones. You only buy the parts you want, and don't end up with a box full of "take offs".

What's the barrel twist on yours? Mine is a 1:9 twist. I went through one scope thinking that was the problem,got another and still couldn't get it to group. I switched to lighter bullets and got better accuracy with 45gr. and even better with 40 grain bullets. Anything about 45 grains won't shoot very good in mine at all.

1:8. Should handle light and low side heavier bullets.

This.

Have you tried shooting off bags or a bipod and rear bag? I ding my shooting worse from the lead sled type rests.

Negative.

Get a 20 inch barrel if you want less than 1 MOA. Other than that 2-3" is standard for 16".

Your right, shorter barrels dont group for crap.

[SC-Texas]

Did I miss the part where the o p gave us any useful info that could actually help him? Like who built the rifle, how long is the barrel, who built the barrel, what triggers in it, is the barrel free floated, what optic are you using, what triggers in the gun? You might even look into the buffer and buffer spring.

Edited to ask what is the twist rate on the barrel? What is the muzzle device?

What gas block is on the gun?

Yeah, he gave us some of that info in little bits and pieces throughout the thread.

Anderson mfg. complete "mil-spec" rifle
Factory hand guards
1 in 8 twist
Velocity trigger is the only upgrade

Assumptions made by me...

16" barrel
Standard carbine buffer and spring
A2 flash hider
FSB gas block

No earthly idea what optic he is running.

It may be hard to get better than 3 or 4 MOA with a one power red.
