I finally got it. My very first AR 15. I'm a proud peacock. I just purchased a used but very good conditioned Hesse AR15A2 rifle. I was testing it out and it shot very far to the right. I moved windage drum all the way to the right but I'm still off about 3-4inches at 100yrds to the right. I tore apart the front sight assembly but it looks as though I cant shift the front sight at all. What should I do??? Remember I got it used so I cant complain to loudly to manufacturer lol.. any suggestions????? Many would be great if you have em.

Thanx crow

ugh... well, after thoroughly cleaning the thing, inspecting the muzzle for dings, and all that... hrmm.

can't torque the front sight base off center 'cause then you screw up the gas system. ummmmm.... I can think of two solutions.

One -- have a new off-center front sight post made up by your local smith.
not a great solution, and ugly, but prolly the cheaper.

Two... get a new barrel. See how said new barrel shoots.

Or the easy way.... get an optic mount and forget about the irons. :)


-K

hrmm.. last thing I can think of -- maybe the barrel is put in wonky, not quite square to the receiver? If so.. perhaps stoning the base of the barrel where it contacts the receiver would help? WAG there.....

Now I know why you're a Moderator, Kaylee.:)

Remove the windage drum again and check to see how the hole for it was drilled. It may be off centered. Hesse's jigs aren't the greatest. There's also an alignment tool to check that the front sight is perfectly aligned with the handle. Try using a yardstick.

Alternatively, get a cheapie scope mount and scope it to see if it shoots straight.

I was testing it out and it shot very far to the right. I moved windage drum all the way to the right but I'm still off about 3-4inches at 100yrds to the right.IIRC, you move the rear sight to the LEFT to shift the shots to the left. Did you misrepresent what you did? Moving the peep to the right will shift your shots to the right even more. So, can I solve your problem by saying, "Move the rear sight to the LEFT to shift your shots to the left." Were you trying to adjust a front sight (the M-16 front sight is adjustable for elevation only) then you'd move it the opposite direction of where you wanted the shots to move. Get it?

[gun-fucious]

sounds like a canted front sight base due to an improperly installed barrel

[BDM]

Dosent surprise me from something made by HESSE.

I was thinking something along the same lines as you. It would great for him if that was all that it was.

*heh* silly me... could be.

must be my Southern heritage..

Most probably the barrel is not centered on the receiver. Remove the gas tube, and loosen the barrel nut. Make sure there is grease on the threads. Make sure the alignment pin on the barrel is centered in the hole on the upper receiver. Retorgue the barrel. Loosen the barrel and repeat. Do this one more time. Three times torquing stretches the threads and helps center everything up. It's fixed every AR I have seen with this problem that didn't have a bent barrel. And according to the TM, it's the proper way to install the barrel.

Just be carefull not to shear off the barrel indexing pin its a softer steel and easy to do if you are not careful.If all else fails get rid of the hesse rifle and get a bushmaster or rock river even colt,hesse was not known for quality and if you have never done a barrel before find some one who knows what they are doing,over tightening of the barrel nut can cause problems.Another reason could be the front sight assembly is off.Take it to a smith who knows ARs or send it off to bushmaster they are always willing to help and if you buy the parts from them they will install them and labor is free.

[JCox]

Crownsnest,

Let me first say that I WAS a "not so proud owner" of a Hesse several months ago. 2 of them to be exact. Nothing but problems. I would check all that what everyone posted but if I had to guess based on my experience, Jeff is correct. The reason I say this and say this alone is:

On my first Hesse, the bolt and barrel was not inline. The little splines on the bolt were hitting the inside of the chamber everytime it fired and finally broke all of them but one after 32 rounds.

When they sent me another, you could hold the gun up (barrel pointing at the ceiling) and look at where the gas tube came down through the forearm and then into the receiver, it was OBVIOUSLY out of line:banghead: I returned it and finally after 6 months, I got my money back and went an purchased a Bushmaster.

I hope you didn't pay a lot for it. My suggestion would be that if you purchased it from a dealer, take it back and get your money back. Just tell them you are not liking the way it is shooting. If you got it from a individual, you are probably stuck with it.

Seriously, I'm not telling you this for the hell of it. I'm dead serious. Goto AR15.com and do a search on Hesse or Vulcan. BTW. It was Hesse and because of the bad raps they changed their name to Vulcan Arms.

Good luck:confused:

[telewinz]

Whats done is done. As stated before, the solution that doesn't risk further damage to your gun is buy an AR scope, you will probably enjoy the scope more anyhow. Number two, trade off the Hesse for another AR15 and run out the door.:D
If you are like me, option number two is the best, you are going to get rid of the Hesse sooner or later, make it sooner. The defect and apparent poor quality will "bug" you until you do. Just hold your nose, walk into your local gunshop and get it over with. "If your eye offends you, pluck it out" which means for the layman " if your AR sucks, dump it". If you keep the Hesse, within 90 days you will loose your mind and become a drain on the tax-payer. Do your duty to your country, DUMP THE HESSE! Time heals all wounds, do as I suggest and you will be on the road to recovery. Even if you have to breakout the credit card to correct the situation, do so. You can't put a price on good mental health (although my health plan does).

As NIKE would say....JUST DO IT!... I think JCOX is the voice of experience.

OOPS. time for my treatment, now wear did I put those rubber shoes?:D

This is not a rare problem at all. A couple years ago, Bushmaster had a lot of rifles leave their factory in this condition. And, it is easy to fix. Jeff White of course has the solution. The barrel is not indexed correctly.
Working on an AR15 is not difficult in the least and you can fix this yourself.
Go to AR15.com and download the armors manual for the M16, it is in PDF format.

[Steve Smith]

I agree with some of the gentlemen above.

The barrel is not properly indexed.

[gun-fucious]

of course one can always just "Tweak" it with a rubber mallet to good effect

[Badger Arms]

Sorry, guys. I'm having visions of this guy poinding away at his front site with a mallet only to find out he needed to move the rear sight the other way.

MAKE SURE YOU WERE ADJUSTING THE REAR SITE THE CORRECT WAY FIRST. From your message, you were not. Always try the simplest thing first.

[Steve Smith]

Badger, you are right. I had obviously misread crowsnest2002's post and thought he was shooting to the left.

Crow, move the rear sight in the direction you want the bullet to go. In this case, left.

[444]

I just assumed that he used the wrong word, as I have done many times. By all means, move the rear sight in the direction you want the bullet impact to move.

[j.wise]

444 is correct. After I bought my very first AR-15 a few years ago, I shot it to discover the darned thing hit WAY left. I had to adjust the rear sight ALL the way to the right, and that just wouldn't do. To my horror, I had to face the fact that my brand-new Bushmaster was not "right."

It got sent back to the factory, where I'm sure they re-installed the barrel correctly, fixing the problem.

So don't be too glum. If the problem isn't the easy fix (move the rear sight to the left), then it's probably the barrel installation got botched. Fix it the way they described, and I'm sure your rifle will shoot like a champ.
