Home Forums Hunting & Shooting AR and Tactical Rifles Ultra Low Scope mounts on AR type rifle

Last year I shot a big doe at almost point blank range from a tripod stand I was hunting. The bullet hit a bit low in her shoulder necessitating a second shot. I have a VX6 1-6x24 on the 6.8SPC and I am considering taking it out of the LT-104 and putting it in these mounts. The gun does not have a front sight base nor flip up sights, it is a pure hunting rifle. Is there any draw back to these mounts? Has anyone used ultra-low scope mounts and found any problems using them regards real life getting an image in the scope and shooting?

Are you going to be able to get your face down low enough on the stock? That is the critical component. The guys mounting scopes for Highpower service rifle are using mounts that put the centerline of the scope about 1.3" above the top of the rail. That's where mine are as well. I wouldn't be able to use those mounts at .875" above the rail. Never get my eye behind the scope.

ditto what gzig5 said.

I don't know! Hope someone on here has used them.

I tried warne highs, and it was torture trying to get my head low enough to see through the scope. I think those ultra lows would be a total non-starter.

Aim a little higher for up close shots.

See how much money I saved you?

A training issue, not a mechanical issue... 100 yard zero and put more rounds down range.

I saw a famous gun writer try an AR once in a gun rag and his scope was mounted as low as possible. He had a terrible time getting behind the scope, they just weren't his cup of tea.

are you blaming the current mounting setup for hitting low? I think you would hate to have a scope mounted that low, an AR is totally different when it comes to optics height than most bolt guns. most people prefer about 1.5" top of pic rail to optic center line. I personally prefer a tad higher at 1.7" ish

Being very familiar with Larue, those rings were designed to use with a 3/4" or 1" riser on an AR then be able to take off & put on a picatiney rail on a bolt gun. Keep notes on scope settings & you can use on several rifles & be good with zero. I can only afford one $2500.00 scope now so I use it on a .204 24" varmint AR with a 3/4" riser & Warne medium QD rings then switch it to my HS Precision 220 Swift bolt action with a Talley rail.

With std height AR mounts you're only ~2" low at 10yds, ~1" low at 20yds, and about dead nuts at 50 when zeroed at 200 with the 6.8. You kinda need to ask yourself if that's really a problem?

I shot a buck in the base of the neck at 20yds weekend before last and pretty much hit right where I aimed.

I wouldn't sweat it as the point blank shots are a rarity in the real world.

No I just go back and forth between a couple of bolt guns using talley LW low mounts and a couple of ARs using the LT-104. The deer do wind up dead, it's just a simple excercise in looking to maintain consistency across the guns I use.

Point taken however thanks for the all the feed back and I guess low mounts won't work well.

extra high rings have always worked for me, needs a lot of cheek pressure genearlly for me but not enough to worry about.

Strictly hunting guns.

Position guns I want a riser and move it forward.


And yes, practice some helps too as is.... if you think you had a problem, try a suppressed 300/221 out to 200 some time... I have to have zeros ever 25 yards to 150 and more often past that to get to 200.. takes knobs and a rangefinder...

You will get the same results on irons or optics on any gun up close... the barrel is below the sights... I just glance and realize I'm going to be an inch or two inches low or whatever on snakes and aim to consider that.

I prefer the AR mounts to be able to cheek weld. Ive tried highs and Xhigh weaver style rings and couldnt shoot them.

From research the LT-104 has the reticle 2.7 inches above the bore, I am thinking about 1 inch higher than a std bolt gun reticle.

Did I mention 100 meter zero?

Yes you did!

Many of the AR shooters use Picatinny raisers 5/8th or so, just so they can use normal rings.

Bushmaster has some cheapo ones that aren't bad, or you can go head first and get a Larue LT-101 to LT-104 type...

Mount yourself a Mini Vortex Venom or Burris Fast Fire Red Dot next to your scope for the really close shots

Probably so, but what I would look at is the distance from the top of the stock not the bore. This would make a better comparison in terms of fit, maintaining proper cheekweld, etc.

The problem is the offset of the shot up close not the fit or cheek weld.

A bolt gun with a 1.5" above bore scope will shoot 1.5" low at 5 yards. The AR will shoot another inch lower due to a higher mounted scope.

Hand a guy an AR sighted in at 50 yards and let him shoot targets from 50 yards out to 300 yards and then throw one in at 10 yards under time and he'll more than likely shoot low. All this thinking of 1.7" high at 100 yards, dead on at 50/200, 4" low at 300 gets confusing under stress.

Sight one in at 100 meters and all he has to think of is aim high.
