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

Hi Stephen - The BDC is calibrated for the M855 (62gr.) through a 16" bbl. Which is weird because the TA-31 series are calibrated for the 14.5" bbl the mil. uses. If you're concerned about using M193 (55gr) w/this optic, your worries are unfounded; this optic will deliver tight groupings using either the M855 or M193. If you're ''on the fence'' about this particular model, jump off that sumbitch and get it; I prefer the TA01NSN over my other TA-31s (A4 & M4 RCO models). Any other questions, don't hesitate to drop me another note... Best Regards, Tim p.s. I also have an Elcan DR Specter and I'd still grab the AR w/the TA01NSN sitting atop it; it's built like an Int'l. Harvester...

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.

I have mine mounted on my Bushmaster .223/5.56 and it works great. If your rail is the same as that on an AR, then it should work fine.

I have a Mark AR MOD 1 3-9x40mm, and have ordered a different BDC dial from their custom shop to use on my 6.8 SPC II flattop. You provide Leupold with the particulars of your favorite ammo. In the case of a 308 Win, I might have a dial made for a 168 gr OTM with muzzle velocity of 2650 f/s. I think you can have just about any caliber and ammo matched to a custom dial for several of their scopes. Contact Leupold custom shop.

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

I have an LR-308 AR10 platform rifle with fixed front sight and measured the aperture position from the picatinney rail to the carry handle and the MBUS locations and found them both to be the same at approx 36.25mm. It should work fine.

You could use it, but I would not. This scope is optimized for the .300 Blackout cartridge, so you would be defeating the purpose of the BDC program on the computer. I would by a 3X9 variable power BDC scope from Nikon for your .308 rifle.

Sure you can, why not? It's pretty darn accurate on my 556 at 400-500 yards, have not tried it on my 308win but I'm assuming it would be even better. Keep in mind this is really a TA31-ECOS. Read all the comments before you buy.

I have M&P 15 and it brings you to the perfect height. Works well with both scopes I have. Red Dot and UTG x9.

That is correct. It works well on my AR 15 (223/5.56) and Galil (223/5.56) but not on my FAL (308/7.62). It compensates for drop over distance so is inaccurate for the larger calibre.

This is a 5.56 (.223 Cal) tool for the AR-15 bolt. I don't know if it would work on an AR-10, since it is 7.62 or. 308 Cal. I would imagine the bolt pieces are a diffent size on the AR-10.

The 716 is sigs version of the AR10, gas piston impingement instead of direct impingement (nice...) , so long as the Barrel has the 5/8"x24 TPI Thread. If your rifle has the standard bird cage, then it should work just fine.

Mine moved around quite a bit but it was on a 308 that jerks alot. If you have a built in pic rail it would be fine.

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'm not sure Greg. The elevation has considerable adjustment range. However, I zeroed in at 50 yards and haven't touched it since.

I use it in my AR10 308 and have had no issues. It's well made and looks great and can more accessories with the rails it provided on top. I like the mount so much I bought another for my AR15. Hopes this information helps in your decision process.
