User questions & answers

Question:	Will this work on a Tikka. .270 Winchester
Answer:	That is correct. I'm sure it would also work with other 30+/- cal barrels as well.
Question:	So the largest adapter isn’t working for the 12ga as stated. So what now
Answer:	Hello friend, yes, this kit is coming with a full set adapters & screws. If later you need extra, you can buy the adapters & screws on our page.
Question:	What is the minimum pistol barrel length required for this to work
Answer:	In the description it says it will fit a .22-.50 caliber, so I'm guessing it will work. I used it to sight in my .300 winmag and .50 muzzleloader and it worked surprising well. I sighted it in at approximately 20 yds first, then backed up for the final adjustments.
Question:	Will this work on 22 cal air rifle
Answer:	I received two 3 packs of LR44 batteries which work for the red laser but no CR2's which work the green laser. The red laser works fine with the included LR44's, I had to to order CR2 batteries and they have not arrived yet so I can't tell you if they work and turn on the green laser.

Question:	Does this really work on .177 cal
Answer:	Hello USMC DEVIL DOG, We appreciate your inquiry! The screw is roughly 6 mm., however we would only recommend this part for a bicycle seat post. If you have any additional questions, please feel free to reach out to us at 1-877-BIKEAID (245-3243) and we would be happy to assist you!
Question:	Will this work with a .44 caliber bore
Answer:	The shaft of the bolt is approximately 2 inches.
Question:	How do you open the darn thing
Answer:	At close inspection, it's tough to tell. The threads appear to be metallic. Either way, I've yet to have problems with it. I purchased two of these a year ago, and they are working like a charm.

User questions & answers

Question:	Does it work with 8mm rifle
Answer:	Absolutely.
Question:	Can you use this to sight in long distances? how due you figure trajectory with grid
Answer:	This device will bore sight a scope so you can hit the target at 50 yds. Typically, It gets me within 10 inches of point of aim first shot. It optimally works for a center of bore to center of the objective lens distance of 1 1/2 inches. Long distance sighting is up to the shooter after you align the scope by firing and adjusting the point of aim to zero it at whatever range you wish to use as your zero. The grid has nothing to do with trajectory, it just helps boresight the scope right after it is mounted.
Question:	So what if your rings are high or low? how does bore sighter line up to scope
Answer:	it is set for standard mount rings. I have high rise rings and you have to guess where to set it . using the grid on bore sight its easy once you know where to set it
Question:	how does it work , please explain
Answer:	Mounts in the barrel as previously described, comes with arbors that work from 22 to 45 caliber I believe. The optic part sticks above the barrel and in front of the scope. Looking through the scope and into the boresighter, You will see a grid. My experience has been that the center of the grid is off (will not be the point-of-impact). I have to typically center the reticle about 2 marks low on the grid, it varies slightly depending on which gun I mount it on. Also, will not work with many rifle sights since the sights will be well below the boresighter. Also, AR types may have problems as the scope centerline will be above the boresighter. IMHO, it is much easier on bolt action rifles to do it the old school way, just sight down the barrel and line up the scope.

Product description

This kit includes the most popular caliber on the market, so you can use zero different rifles, pistols, shotguns and muzzle loaders. The pursuit of the sight is designed to save you time and money by allowing you to pre-tune the oscilloscope. The final step in zero should be completed within that range.

User questions & answers

Question:	Will this work with a 300 win mag
Answer:	yes it does. I have used it with my 300 WSM
Question:	Will it work on a Barrett 50 bmg
Answer:	Yes, it will work on .50/.500 calibers. Works on everything from .17/.177 to .50/.500 and has arbors for 12ga. slug guns.
Question:	Will this work with a red dot scope on a
Answer:	Yes, this will work on your 5.56/.223 rifle if it is a flat top rifle. By flat top, I mean it does not have a scope mounted on the carry handle. If has a removable carry handle and you remove it and mount the scope without the handle it will work perfectly. The carry handle is the problem. If you have a scope mounted on the carry handle like I do on my A2, you will need a laser bore sighter, either the kind with the taper mount that sticks down the bore, or one that looks like a rifle round that fires the laser through the chamber and the bore. I used the laser that look like a rifle round to bore sight my A2 with the scope on the carry handle.
Question:	Will it work on a 270 and 243 rifle
Answer:	I just sighted in my 223/556 bolt and 308 bolt with it. I just need to get to the range and tweak it. So I'm confident 270 and 243 shouldn't be an issue. It has arbors from .177 to 50 cal

Product description

The SL-100 uses a red laser and has approximately 2 hours continous battery life. It's guaranteed more accurate than any other boresighter. That's why the US Navy and USMC selected our boresighters, over all others, for their Aviation Unit weapons from 5.56mm to the 20mm canon on the AH-1Z Cobra Attack Helicopter. In addition, the US Navy is using our boresighter, with our special adapter, for the 25mm Gatling Gun on the new F-35 Strike Fighter. The SL-100 includes all adapters to fit .22 cal. To .50 Cal. & 20 and 12 ga. shotguns. The system also includes our Ballistic Targeting System software program to create a custom laser boresighting target for your specific rifle and ammo. All Sitelite Mag Laser Boresighters have a lifetime warranty. And, an optional app is available for your iPad and iPhone for use in the field.



Troubleshooting:

NOTE: THE BATTERY CAP THREADS & HOUSING MAY DEVELOP AN INVISIBLE OXIDATION OVER TIME, THEREFORE, THE THREADS MAY NEED TO BE BUFFED (VERY LIGHTLY) TO REMOVE THE ALUMINUM OXIDATION. IT IS RECOMMENDED TO USE STEEL WOOL OR A PENCIL ERASER TO REMOVE THE OXIDATION. THIS WILL INSURE A GOOD ELECTRICAL PATH. CHECK THIS, FIRST, IF THE LASER DOES NOT TURN ON PROPERLY.

• Guaranteed superior accuracy with a lifetime warranty

User questions & answers

Question:	Can you see the laser pretty clear in daylight
Answer:	Yes
Question:	Will it work in the Ruger
Answer:	Don't see why not. It comes with adapter o ring for most any caliber
Question:	What is the shortest barrel length that will fit the bore sight into the barrel. An NAA mini-revolver - 1-5/8" bbl? A Berreta Bobcat
Answer:	I have a Beretta 3032 tomcat and that barrel is 2.4" and it certainly does not fit. it extends 7/8 of on inch longer than the barrel. I think it would be safe to say It would be too long for your NAA Mini.
Question:	Has anyone used this on a stainless barrel? I read it uses magnets in addition to the O-rings. Wondering if this causes any problems with stainless
Answer:	I here people say "It is not PURE stainless" or real stainless is not strong enough. Its a 416 stainless meaning it has carbon in it. It is ferrous. "Real" stainless or 300 series isn't magnetic at all. Gun manufacturers don't use it because it is gummy and does not hold shape as well. Its purpose is better suited for wear resistance on static non bearing surfaces. Remington found this out the hard way on their 1911 pistols.
