Seems that there is a problem with accuracy when using the Standard Isue AR15 Sights.. Any feed back on this..

Tell it to the Marines! They qualify at 500 yards with those sights. What problems have you heard of? Don

Got an email from my Son in NY.. Says that he can't hit anything with the Sights that are on the Gun.. Is there a difference with the Civilian version..

Nope, not that I know of. The only major difference is the firing pin.

I've known guys that were in the military say that they couldn't hit a thing either until they were instructed on the use of the aperture sight. Another factor is the rifle itself. There are so many variations on the market now, including various calibers and twist rates. 5.56 NATO ammo is not interchangeable with .223 Rem. ammunition, even though many use both in the same gun. I'd start with the basics, make sure the ammo matches the barrel and the correct bullet weight for the twist rate. If it has the A2 sights, you can always mount a scope on top of it and determine if it's the sights or something else causing problems. If it's an A3 design with a detachable sight, just detach the sight and try a scope on it. Don

He says that the problem is a PEEP sight on the back, and a Post in front.

PEEP is another term for aperture sight. The peep rear with the post up front is standard and has been since the ARs inception. It's designed for speed and the ease at which the average soldier can be trained to use it, but with proper training and usage can be very accurate. Don

The A2 has a flip sight. One for close range and then it flips forward for a longer range peep. I had one in my hands last weekend. They are much better than what I had.

Let's put it this way, the sights on the AR series of rifles are some of the best out there on the military type rifles.
Specifically what is his gripe? How far out is he shooting? Has he ever shot peep sights before? How much time does he have behind a rifle?
Hit that link for appleseed that Don posted, get him to get some info/do some reading on their website, and then find out what isn't going right for him.

He might have a percepton problem, when looking through a Circle. Might be the Ammo, or Maybe something is wrong with the Rifle.. He bought it used.. He also belongs to a Shooting Club. Got more guns than a country Gun Shop. LOL... NYS Anti-Gun lobby hates guys like that..

I am going to guess that it could possibly the ammo. I am thinking like Don in that it maybe the ammo choice. He would need to check and see if it is a .223 or a 5.56, then find out the twist rate.

The barrel says 5.56. I haven't had time to look for a twist rate. My boss shot the rifle before reporting for active duty last month and couldn't get any thing close to a decent pattern even when benching it. It'll be a real bummer if its the wrong ammo as I have a ton of .223 ammo.
Above, is Message from Scott....

Check this link on the differences between .223Rem. and the 5.56x45 NATO cartridges. en.wikipedia.org/wiki/.223_Remington While you should be safe in firing .223 ammo from a 5.56, the reverse is not safe. The differences in rifling twist rates vary quite a bit between different 5.56 barrels depending on the weight of bullet it was designed to use. The wrong weight bullet will not be accurate and may not even stabilize properly in flight. Just something simple, but it might be a good idea to give that barrel a thorough cleaning. Those bullets move awfully fast and can leave quite a deposit of copper in the barrel. Built up over time it negates the rifling. That will definitely mess up your accuracy. Don
