Bore Sighter and TopShot BS!!!

[ZX-10R]

So I get to Santa Barbara and my friend's place. He tells me he got a bore sighter...I see it is a magnetic one that goes on top of the compensator. So I am geeked and put it on my PSL. It matches up...So I proceed to put it on my WASR and AR. We do it for all out guns. I go to the range and F**K!!! All my shots through my AR and WASR are not even on paper at 50 (I start at 50yrds).

So I am l saying to him what a POS. So I sight in my AR and AK again but spent some ammo doing it since i did not want to remove my scopes which are all mounted. He challenges me to TopShot contest using rings and two targets. I am still not 100% sighted (Keep in mind the last time we went if he challenged me it would have been no contest. I shot and everything has a spread that is shameful. 10 shots bench, 10 standing, 10 kneeling. Using points we make up. I totally screw up and take the challenge even though I am not fully sighted in.

He is running away benched as I am sighting while this is going on...My AR was trying to recover from the mark of Kane that bore sighter gave it. Then we get to standing portion and kneeling portion. I kill him but the damage was done. I lose 117 points to 108. Keep in mind, I was down 40 going into the kneeling and standing.

Then we go to the long distance shooting and I kill him at 100yrds. Then my PSL stops firing. I open another pack of 20 and nothing. The primer looks hit but only a slight dent. The contest is over and I won that portion but since I could no longer shoot the day is done...Bore sight BS, TopShot humilation, and now my PSL is not firing.

I get home and think the pin is snapped inside. I knock out the retaining pin that holds the firing pin and it took almost 30 minutes to do since I do not have a press. For some reason it got junk in it even though I clean it regularly now. I clean it with brake cleaner and then oil it and boom it is fixed!!!. I compare to my WASR firing pin and it is smooth again...

It was a bad gun day which is definitely worse than a bad hair day

I did find out about a 10/ 22 shoot off every Friday...Now I will need a 10/ 22 and cash to deck it out for this. One guy brian was literally knocking the staples through the target to take the target down with his 10/22...Amazing shooting.

That was the best part of the day haha.

Sounds like fun, you should have challenged your friend to the elimination round...

I hate those magnetic bore sighters as well. I tried them and didn't like them at all. The laser bore sighters are a bit better.

is it like hte leupold one? never figured out how they work.

I've always been surprised how inaccurate my laser bore sight is when compared to where my shots actually hit. I have one that goes in the barrel tip. Now what I do is sight a firearm in at the range, then when I am home see where the bore sight says it is hitting, then remember how far off the bore sight dot is from my already sighted in optic. Then next time I need to sight in an optic I can with the bore sight, now that I know how far off I need to go.

I find it easier to look down the bore at an object and use that as a rough sight in. Then start at 25-50 and work from there.

Yeah it screwed the day up as I had my AR and AK tight...Then I had to start over. I swear I should have stepped on that thing. It was fun for sure. Same regulars who shoot every week...Wish it were in Irvine area as opposed to me going to San Luis Obispo. I know there are rangers down here but I like that range.

So it is a laser atop a magnet. The thing is, it has not adjustments for diameter...You just eyeball on top of the compensator and then look through your scope or sight. IT was horrific.

This is a good way to determine this. The thing for me is the PSL sighted right with the bore sight but the AR and AK were wayyyyyyyyyyy off. I will try this if I ever use that thing again...Likely not though. Usually takes me 10-20 rounds to sight where minimal adjustments are made.

I usually start 25yrds and then go from there as well.

I don't know if you guys have telescopes, but I can usually visually align the tube more accurately than with the small cross hairs. This is just a coarse alignment on a star....

Those little boresight lasers (scopes or rifles) are notoriously misaligned. And almost impossible to align perfectly with setscrews. Set it on a table, and it's misaligned again - soemtimes not much, sometimes a lot. I used to try to align scopes using a similiar device. Once again, visually, can do a quicker job.

Bottom line - eyeing down the barrel can be very accurate - at least enough to get close.

Just my 2 cents...

I have the kind that is shaped like a cartridge and goes in the chamber. I sight in to the dot at home before going to the range. Then start at 50yards. I have found that doing this so far it consistently starts off being about 4" high and 3" to the left at 50yds. So it just gets me on paper and adjust from there.

The thing I dont like about it most if the short battery life. It takes 2 small watch/calculator type batteries and you literally get about 5-7mins of bottery life and I've not been able to find the batteries locally. Had to order them online, but found them pretty cheap so I bought a bunch to have on hand, esp. considering the short battery life.

I take a piece of paper and make two dots - one for sighting through the bore, and the second at the same distance as the sight axis above the bore centerline. Tape it to the garage door (about 15 feet from my bench), making sure that the two dots are vertically aligned. Place the upper (if an AR) or rifle in a secure rest, ensuring that the upper/weapon is not leaning to either side. Sight through the bore if an AR upper or bolt action, or use a laser boresighter if sighting a weapon that can't be directly boresighted. Align the barrel with the lower dot. Secure the upper/weapon against movement and check sight alignment on the upper dot. Adjust as needed to bring sights to upper dot. You'll be on paper at 50 yards, and most if not all the time at 100 yards.
