Laser boresighting rifles

[loadedround]

I have found it both very difficult and inconvient to bore sight a scope on any rifle with a muzzle brake or flash hider the conventional way with a Bushnell style optical Boresighter. I wish to swithch to a laser sighter system and see both the muzzle type and the breech type laser sighters advertised. I'm not concerned about price differences, but wish to know whaich one is the better system. Comments and/or recommendations by users please.

the only problem with the laser bore sighter is the need for more space as the 15 ft from here to the wall just isnt gonna cut it...

PT1911:
Please explain your comment, I'm a little slow these days.

with a bore sighter that is set above the barrel to sight in on the grid, it take into account the distance of the scope above the bore.. A laser bore sighter does not.

Simply put, the bullet cannot take the same straight line path to the POA set by a laser bore sighter at a few feet because a bullet does not move in a straight line, it moves in a trajectory arc.

Essentially, if you attempt to zero your scope at only a few feet, (if you can even get the scope to adjust that low) you will likely be shooting way over whatever your intended target... Laser bore sighters work best when you have at least 25-30 yards to make your adjustments... even then, they are good for getting you on paper, not on target.

I have had just as much luck simply bringing POA of the scope to what i can see through the barrel with the bolt removed.

I have the bushnell laser sight you put into the muzzle and it works quite well. I am not sure about the other breech type laser cartridge but would imagine it may be better. You do need about 75' to bore sight with the laser and to "get on paper".

Either the chamber or muzzle type laser boresighters work equally well. Laserlyte's Kryptonite green laser boresighter is more easily seen in bright light and at longer ranges, like 100 yards, than the standard red laser boresighters. Generally though, boresighting can be done at about 25 yards to "get on paper" then the final sight-in is needed by adjusting the sights or scope reticle until the shots are going where they should.

Our local gun shop has a Bushnell? optic boresighter, but would not work with my AR due to scope height. Since I have a number of rifles (laser boresighters save more time/money with numerous guns) I sprung for the Laserlyte Deluxe Universal Laser Bore Sighting System model PLB-0001-140, which I found online for around $100.

A wee bit pricey, but it comes with a nice hard case, lots of collets, and had some stainless steel/brass parts vs the all plastic of their cheaper models.
Looks like they now list it as a first generation laser-you'll have to do your own research to see why you might want a newer model?
Just a quick glimpse at their site and it looks like maybe they're trying to force you into buying the twice? as expensive green unit if you want the storage box/accessories I got? All the other pix I looked at seem to be all plastic-not as nice as the first generation unit I bought.

FWIW-I simply measured 100 yards from my bedroom window-at night (after all the neighbors are asleep ) I propped all the rifles in the bedroom window and used the laser boresighter to sight 'em in at 100 yards-neighbor a few doors down has a storage shed that's exactly 100 yards from my window.
When I got to the range, all my rifles were on paper @ 100 yards, 'bout 3 inches off-only took a few shots to fine tune 'em.

Should I ever need to use the laser again-well, the neighbor's 100 yard shed is still there!

You can boresight short range such as 40' across the inside of a house. Just use two small target stickers* on a piece of paper with the centers the same distance apart as the scope centerline above the barrel bore. Use the lower target for the bore and the upper target for the scope (obviously).

When I've done this with centerfire rifles I've been on paper at 100 yards. Usually as much as 6" high, but still on paper.

Originally I bought a laser boresighter that goes in the muzzle (similar to the Laserlyte linked above) but it went out of adjustment after a couple years, and it wouldn't work with several AR muzzle brakes (because the mouth of the muzzle brake isn't cut as precisely as the crown of the barrel, and that is critical to the function of the unit). Soon the battery failed and I discovered that the battery is not replaceable, but the switch was going balky so I wasn't sad to throw it out.

So now I have the cartridge type and I am happier, even though it is more expensive. I got the AimShot because it has arbor adapters for all my rifles, including 300 Weatherby Mag. Total cost is much higher than the muzzle type, but I'm much more satisfied. And if the diode module goes out, I just buy another one. The rest of it still works.

Dunno what model you had, but you can replace batteries in mine.
I just did a quick check at LaserLyte's site-the owner manual for the deluxe model they're selling also shows how to replace batteries.

No need to be confused, friend. It doesn't reflect badly upon you.

Mine was model #205. "Lifetime Battery" is printed on the box. It didn't last a lifetime. The other problems were the equally vexing.

When it was new (and when I used it with a well crowned rifle or pistol with no compensator or brake) it worked well. It just seemed to have such a short life.

My bad-I was thinking LaserLyte when you said "similar to the LaserLyte linked above"-I'm assuming yours was a different brand.

Cool. Yes, I always assumed that I just bought the wrong one. It was probably a cheapie, but the only one available at the time. I always seem to learn that lesson.

A good, high quality boresighter will probably work if used properly, unless it doesn't physically fit the gun. As everyone notes, it doesn't zero your sights, but it puts the shot somewhere on paper and you can zero it from there.

Personally, I feel the leupold zero point boresighter to be the most efficient way to boresight a scope. Done correctly you can sight a new scope in with one round (plus a group to verify).

The only drawback is that it is very hard to impossible (depending on barrel length) to sight in iron sights or a red dot with it.
