Will I have any clearance issues with this combo? Looking to get the lowest mount possible for this said scope.
Leupold is the 3-18 with 44mm objective

Larue Lt158/Leupold Mk6/Flat Top AR Question
- Thread starter Pusher591
- Start date
Here's the formula again (assuming a monolithic/same height receiver/handguard top rail):
[(G)+3mm-(Z)]/2=Min. Ring Ht. As Meas. From Base of Ring to Base of Scope Tube
G=outside diameter of the scope's bell (~53mm on the Mk6 in question)
+3 for allowance of any caps/covers on the scope
Z=tube diameter (34mm in this case)
SO... [(53.4)+3mm-(34)]/2 = 11.2mm base to bottom of your ring OR 28.2mm base to ring centerline (OR...since most rings are advertised in non-metric terms, 0.44" or 1.11" respectively).
Given that the LT-158 is 1.44" base to centerline, I'd say you'll have ZERO problems with that optic, but depending on how your rifle is setup, how you are built in terms of your preferred ring/mount height on an AR, etc., you may want to go slightly lower than the LT-158 can get you.
If you have to have QD, ADM makes their AD-RECON-SL mount which is about as low as you'll find for a 1pc, QD setup and it sits at 1.19" base to centerline which will clear but with a VERY slim margin.
If you want to skip the QD, there are a variety of options that will get lower than the LT-158, including but not limited to the Badger Ordnance 34mm Unimount at 1.30".
Just some things to consider!
Thanks ORD, that's the kind of great answers I look for when I ask a question here. Looks like I may have to go with some rings to get as low as I want to go.
I went through the same mounting issue but w/ a Leupy Mk6 1-6x 34mm that I got for my LMT LM8 MRP.
I wanted QD and very low, so I went with the AD-RECON-SL mount that ORD recommended. Height placement is just as he said, but the other factor to think about is your stock set-up and how high (or low) it puts your sighting eye at cheekweld. The SOPMOD that came with my LM8 didn't work well w/ this mount, and because I still wanted to run a light-weight collapsable stock, I picked up a CTR with LT's RISR cheekpiece. That combo worked perfectly for putting my eye at the correct height and, obviously, the CTR is adjustable to suit your particular LOP.

This is how I had my Bushnell 3.5-10x45mm scope mounted. I really like how my cheek weld was with this mounting. I then took some advice to change the mounts to this Nikon P-series rings. With the new rings it lowers the scope a little and looks better then the old setup. These rings force me to push my cheek down to allow me to see through the scope. I am not real comfortable with this cheek weld. With the old mounts my cheek weld is very natural and is very fast compared to the new one. A lot of the Nikon-series are used so they may be good for you. I'm going to try and see if I can get used to the new setup before I change it back.
PS: I had to turn the rear mount around because the new scope eye piece would touch it. The new scope is a Bushnell AR/223 zoom with 4.5-18x40mm power. I like to have high power for long range and target shooting.
