Rich Langner, President of Concept Development Corporation (CDC) invented the first practical laser boresighter over 10 years ago. Today, CDC manufactures thousands of SITELITE Mag Laser Boresighters every year. Over 100,000 SITELITE Laser Boresighters are in use by sportsmen, law enforcement, and all branches of the U.S. Military. The U.S. Navy uses them on their Blackhawk helicopter gunships and on ships. The Marines use them to boresight and test weapons at their depot. The Air Force uses them to boresight their M16 rifles and Army Special Forces use them in Iraq.

Concept Development Corporation has developed and tested all types of laser boresighters. The SITELITE Mag Laser Professional Boresighters have proven to be the most accurate, reliable and cost effective boresighter available.

The SL-100 and the new SL-150 use super strength, rare earth magnets to hold the laser, securely, within the bore for consistent accuracy. Various size o-rings are used to guide the precision stainless steel muzzle adapter into the bore with no metal ever touching the rifling. The anodized, aircraft quality, aluminum housing contains the laser which is precisely aligned to the center of the bore.

A calibrated target is used at 25 feet to sight-in for 100 yards. The unit also includes the Sight Alignment Verification Target (SAVS) which records the final adjustments of each rifle so you can instantly verify sight alignment in the field. This is especially helpful after traveling or if you drop your rifle.

The SL-100 and SL-150 fit .22 to .50 caliber bores plus 20 and 12 gauge shotguns without having to buy extra arbors or sleeves or anything else! They are boxed in a rugged carrying case and have an Unconditional Lifetime Warranty...no matter what!

Rich Langner, a Vietnam Veteran Helicopter Gunship Pilot, is a staunch supporter of our troops. Last year, he found out that individual troops were buying the SL-100 from Cabela's or Bass Pro with their own money. Here's an email he received from Iraq:

"I am deployed to Iraq with the U.S. Army. Due to adding accessories such as lasers, red dots and scopes to our weapons, this product (SL-100) was able to get us on target without a range. We knew we could hit a man size target by the bore site alone. This tool is by far the easiest and most reliable I have seen, yet. The Special Forces here even use the SL-100!"
—SPC D.M. (Bagdad, Iraq)

Now, when one of the troops, in Iraq or Afganistan call Concept Development to purchase the SL-100, Rich refuses to sell them one! Instead, he sends them one at no charge. Sometimes, he will even upgrade it to the new SL-150!

Rich says money can't buy the satisfaction he gets from receiving emails like this latest one:

"Hi Rich, Yes, I got the SL-150. It works great. I am amazed at how easy it is to use and how accurate it is. Thank you for your generosity! Its thoughtful VETS like you that make our jobs much easier!"
—SPC T.F. (Camp Speicher, Iraq)

It just doesn't get any better than that!
