Thread: I need some opinions/advice please help!

  1. I need some opinions/advice please help!

    I bought a used hk usp .40 on Gunbroker. The gun appears to be in very good condition and has the np3 robar finish, and trijicon night sights.

    I bought a laser bore sight for sighting in my viridian laser sight. The problem is when I placed the laser bore sight in chamber and closed the slide, the laser was way off from the iron sights. I aligned the viridian laser sight up with the laser bore sight in the barrel. My question is, does this meen that my iron sights are off, are laser bore sights accurate, or does this meen there is something wrong with my guns barrel. Please offer advice or ex[erience with boresights I'm trying to figure this thing out...

    If I remember correctly from my laser bore sight tool, It's not recommended to close the breech. Just insert the laser tool into the chamber with the slide open and sight. Of course mine was for my AR. Check the instructions for the laser.

    I'd be more apt to blame the laser bore sight tool. I recall mine had adjustments to center the emitter diode. A look down the barrel will tell you if you have any damage. If you have any doubts as to your ability and I'm not impugning your ability just trying to make you think about it, take it to a gunsmith and ask questions there. If you don't know of a good gunsmith, ask a local dealer. Most will know of one that they use or have one in house.

    Good luck...
    You can give peace a chance alright..

    I'll seek cover in case it goes badly..

    If the iron sights are adjustable, they probably got knocked out of alignment? Or you could have inserted the laser incorrectly. I'd take it to the range and see if it shoots to the irons before I'd make any changes to them though.

    The're not adjustable, I meen there fixed sights you would have to remove them to adjust them , and I don't want to mess them up. The first time I took it to the range I was doing a horrible job, I didn't know what was wrong with me, but now after using the laser bore sight I'm wondering if it was the iron sights... I'm not sure why they would be off though.

    Have a gunsmith look at it... It's impossible to clearly and accurately diagnose in this medium.

    If you are concerned about the condition and function of a firearm, have a gunsmith look it over.

    Good luck..

    Thank you for the advice. I just figured it might help to get some advice from peoople who have used laser bore sights, before I take it in.

    By what you described, having issues at the range, indicates the irons are off or something else is wrong. An optical bore sight tool and a gunsmith would be the best bet.

    I had good luck with my laser bore sight tool. It got me on the paper with my AR and scope combo.

    Let us know what comes of it..

    They still should shoot to one area, even if they are off, as long as you aim at the same point.

    The thing is, when you look down the iron sights (with the laser bore sight tool in the chamber) the laser projects far left outside the sight picture. But, upon visual inspection of the outside of the gun, they appear to be properly fitted. I'm so confused! Is there any reason the bore laser would project an innacurate impact point?
