Will the elevation metering work on an AR-10 platform style rifle shooting the .308? I ask as my BDC on my Leatherwood CMR works for 556 or 308.

No, it was designed specifically for M885 nato ammunition for either an M4 (zeroed at the 350yard elevation line) or the M16 (zeroes at the 300yard elevation mark). The elevation markings are designed for this specific trajectory and while similar bullets (ie 55gr FMJ .223) can be used with little difference on a AR15 w/ a 16in barrel; i do not believe that a .308 bullet will be very effective using the elevation markings with the Matech rear sight.

Ballistic charts reveal at 600 yards (zero @ 100 yds) trajectory for 5.56 with 55 grain FMJ drops 80.3 inches at 600 yards, and .308 winchester with 150 grain FMJ drops 86.3 inches. Windage, on the other hand is the biggest difference. Data is based on 24 inch barrels. I believe the Matech sight is based on a 20 inch 5.56 infantry barrel. You might want to check on that. Good shooting.

Elevation is set for bullet drop of 556. You can zero it in at witch ever you like however the distance adjustment would not be correct.

Sean,I havent had an oppertunity to try it on my -10 but a sight is a sight. However, the way you zero it for your weapon changes. I think the Matech website gives the instructions for differnt weapons

I have mine mounted on an M&P10; (308). The recoil seems to give the firedot a little problem as mine blinks out occasionally and needs to be turned on again? I have mounted it on my AR15 platform with no problems. It might just be my scope and it may be a defect. However the scope has great optics.

Honestly I'm not sure, I don't know if the .308 butt stock on any ar platform is different from a .223/5.56

I have found it works good so far. I use it on a 223 bushmaster and 308 DPMS with no problems. Easy on and off also.

There is a review in American Rifleman January 2014, they mounted it on a AR10 .308 and they said it worked great, I too will be mounting it on my gunsite scout.

I have it mounted on an AR-10 (.308) with no problems. They say it is rated up to .50 cal but I can't say I tested that.

5.56 to 308 and many in between. I have M39EMR, a AR10 in 300AAC, a LR308, and a AR15 in 5.56 - cleans all. That means anything from 7mm down to 223.

Everything I have read says 5.56. I have seen images that says you can use for .308. I would call and ask company.

I am not quite sure of what you are asking. Magazines designed for use in an AR15 platform weapon are not compatable with magazines designed for use in an AR10/.308.

I have the 1x to 4x. It is not the best scope for any long range accuracy on a small target. But, I do, for what I am using it for in 3 Gun competition, it is working really good for me. Without getting the instructions out again, I can't remember if the BDC radical was caliber specific. I have never found a caliber specific radical to be accurate for me, anyway. So if you keep that in mind I think you would be fine on the .308.

I got an answer indicating the highest power 16x should be used for ranging or bullet drop compensation. Is 10x power specified on the owner's manual by the factory? Thanks

I use it on 308. No problems that I know of as long as you have a rail to mount it on. It's a pretty solid built mount.

It should work...I'm using one with a fixed front sight on a .556, and I've never seen any other height option mentioned for use with the .308 versions.

Charles, I purchased this for a 308 platform. Mount was bent. Went to Burris XD rings. It's a better choice.

Should work well as long as you have a Picatinny rail to mount it or can use the adapter includedI used it on both my AR-15 .223 and Savage Rifle in .308 had no problem with either one

This is to help other Ruger AR556 owners. I apologize posting in this thread. 1" riser did not work for me. It's too high. I'm going to try 0.83 next.

Would work good on a 308. You will need a mount depending on your rifle having a sling stud available. My latest rifle did not, so I went with GG&G; mount to put on the free float forearm.
