Cartridge laser scope sighting?

[hawkeye]

I was wondering if anyone on THIS forum has had any experience using one of those laser bore sighters as seen on all the CTD and Sportsman's Guide catalogs? They have alot of good reviews, but I'm not about to trust some reviews from a website trying to sell me something. At least you guys aren't getting a profit from this post...


I would like to thank anyone in advance for replying to this post...

I use a Sightmark brand one and works fine. It's more than enough to get you on paper. The few times I used it, I was about 3-5" off at 50 yrds

Save your money. If you have a bolt action or AR type rifle, its cheaper to just remove the bolt, look down the barrel, center the barrel on a target at a known distance, and adjust your scope/red dot/sights to the same spot.

I guarantee this will put you on paper, and pretty damn close.

A friend has it for his AR. The first time he tried to use it, it got stuck in the chamber. We had to pry the BCG open using a flat head screw driver. It's good for close range sighting to get you on paper. In reality, the bullet path isn't straight so the laser is in accurate at longer distance.

Yep, what he said...

Thanks for your input guys, I can see the con's outweigh the pro's is against buying it. Purchase averted! I really don't want to buy one and have it get stuck in the chamber.

[damndave]

It wont get stuck in the chamber if used properly. Sounds like the BCG was slammed on the boresighter and smashed it in there.

Your choice if you get one or not though. I use mine and like it a lot.

I have them for almost every cal of rifle I own. Saves me time and ammo.

If it saves you ammo, you are not zeroing your gun correctly. It only takes one round to zero a rifle. Although, I usually take a second shot to fine tune and a third to confirm the adjustments. I am talking about zeroing at ANY given distance. I taught my stepson to zero a scope when he was 13 or 14. He managed to break a clay pigeon on the 1000 yard berm on his third shot. His second shot was just a couple inches low. There have been several theard explaing how to do this recently. You might want to find one or two of them. You'll save a lot more ammo doing it correctly than using a laser POS.

They work great for getting you on paper so within a few shots you can be totally dialed in. I've noticed with mine though that the battery life is VERY short, like just a few minutes, so make sure you have extra batteries. I had to order the batteries online because I could not find them in any local store. But they were cheap.....got like 50 of them on Amazon for about $10-12 shipped. I think I also saw some at the gun show once.

I dont just drop the bolt on it either. I easy the bolt forward with the charging handle, then seat it with the fwd assist.

Also.....I usually hafta use mine at around dusk when it's dark enough to see the laser dot but still light enough to see the sights if adjusting irons or non-illuminated scope. With reddots and such you can do it whenever. Although it gets hard when sighting a reddot cuz the dot in your sight is the same color as the dot from the laser.

My back fence is about 60yds from the patio, so I'll sight from the patio to the back fence and that will usually get me onto the 8.5X11 sheets of graph paper I use for zeroing targets. A few clicks of adjustment after a couple of 3-5shot groups and I'm GTG.

Are you talking about "re-zeroing" and already previously zeroed optic or zeroing a brand new, just mounted on the rifle one?

Cuz I'm mostly talking about rough zeroing a brand new optic. A couple of them I've done would have required more then 3 shots just to get on paper at 25yds then walk it out to further distance to fine tune. Cuz if you tried to start at 100yds the first shot woulda missed the cardboard backer by a couple of feet.

Brand new scopes. I can take a scope, mount it to a rifle and have it in the black after one shot. Again, I can do this at ANY distance the gun is capable of shooting a decent group.

Just bought one of these earlier in the week. At 20 bucks, I figured it was worth experimenting.
It works great. When I thought about it, there really is no reason to buy an expensive one, as long as it is a chamber based device, it will be as accurate as it can get.

The issues with this particular model:
You cant turn it off. Minor annoyance.
The instructions tell you not to actually chamber the catridge as the extractor will probably damage it.

It is still on sale as of this posting.

@tomd1584: Hit it in one in my opinion. It works great if you cant actually look down your barrel while your optic is in place.

@CSACANNONEER: Any links or suggestions for a new shooter like myself on sighting as well as you do?

This thread explains it very simply:

The trick is to have a very stationary rest system.

I got one of those multicaliber doo dads with the plastic chamber inserts for the heck of it. The laser diode is a cheap astigmatic POS and there is enough play that if you jiggle the power cord or even the nudge the rifle while the thing is chambered, you can see the dot move all over the target, like 2-3 inches at 25 feet.

I'm in the "save your money" camp. Like some of the previous posters have said, just clamp the thing in a vise, remove the bolt/ lower ***'y/cover/whatever and line everything up by looking thru barrel and scope.
