Leatherwood ART M1200 6X-24X Riflescope

Just received Springfield M1a m21 yesterday, have not mounted nor shot yet. Very well designed scope very excited to use.

I am truly impressed with MY new Leatherwood ART M1200 6X-24X Riflescope.
Using some pillows and care, over a bunk for stabilization, of top heaviness, sliding the Leatherwood ART M1200 6X-24X Riflescope along the rail mount until adequate eye relief and having the scope mount fall into place so that the scope sits level on the rail mount; required no tools and a thumb and fore finger snug down of the Leatherwood ART M1200 6X-24X Riflescope scope mount thumbscrews.
Once the Leatherwood ART M1200 6X-24X Riflescope was lightly mounted on platform then inspection and familizarization, comparison and contrast with the optical, mechanical analog computer i.e. the Leatherwood ART M1200 6X-24X Riflescope and it's included documentation.
In terms of eye ball inspection and heft in hand MY Leatherwood ART M1200 6X-24X Riflescope appears rugged and built to last.
Reading and following the provided manual, it is possible to research and calculate the trajectory for the platform's projectile. This information allows one to set the Leatherwood ART M1200 6X-24X Riflescope's cam setting which seems to be an elevation angle specific to the projectile's trajectory table. This is important and the manual's instruction's should be followed to get the most precision possible.
With a spot on the wall, a known distance from the barrel's end; using a laser bore site one can center the cross hairs on the spot above or below according to the known distance from the end of the barrel to the spot and the trajectory table, researched and calculated to the platform's projectile.
In the dark, with the laser bore site aiming at a post at the approximate distance for the calibrated zero then the Leatherwood ART M1200 6X-24X Riflescope's one half MOA center dot and the bore site light should be one to one and onto. At this point one should be on target and ready for fine tuning.
The reticle is wonderful.
Optical clarity and low light visibility are impressive.
So far, expectations have been met and/or exceeded.

I am a U.S.ARMY Retired Combat Infantryman Sniper .I was first introduced to the ART 1 3x9 Redfield Leatherwood design scope at the AMTU Sniper School 101st Airborne Div in the 1970's .I have this M1200 Scope on my AR-10 .308 Rifle its a big improvement over the old ART 1 with many features to help you hit your target with phenomenal accuracy .If you shoot a tactical rifle or competition long range You will need this scope .I would like to thank Christopher WU and Culbreth Leatherwood for improving the late Jim Leatherwoods Design of the ART Scope and marketing it at a reasonable price. The Hi-Lux Leatherwood M1200 ART Scope I would have no problem taking it into battle in a moments notice .At the range ringing steel at 1200 yards or in the woods hunting making that long shot count on big game with the snipers ethos in mind "ONE SHOT ONE KILL " be it semi Auto Rifle or Bolt action rifle this scope is for you.

I purchased this optic about 2 years ago and it has been exceptional. It is mounted on a .308 long range precision bolt rifle, and I have had no issues with it... once I got the elevation and cam set for my ammo correctly which was a little tedious for my liking...but WELL worth the time. Being able to separate the cam and the "zoom" rings for higher or lower magnification at any range setting is great. It allows for 100% positive target ID at max magnification, then back off of the magnification to stabilize the image but also knowing that the ballistic drop is set for the range to target especially when shooting out to over 800 meters.
