Frequently Asked Questions

I can see this product, but cannot add it to my cart. How do I buy it?

We are now selling a lot of our product line through partner dealers and distributors. The product description should have directions on where you can find these items to purchase them.

 What is the difference between a Lever and VFZ mount?

The Lever mount is Quick Disconnect whereas the VFZ is not (a wrench needs to be used to attach/remove a VFZ mount). If you have one of our VFZ mounts and wish to upgrade to our levers for a small fee, contact [email protected].

Can I buy just the OBR, PredatAR, PredatOBR, LT-10 (MRGG) upper?
These were only offered as a complete rifle; we do not sell the uppers individually.

Is it possible to get an OBR with a PredatAR handguard, or put an MGU handguard on my OBR or PredatAR?
The handguards are specifically designed for each rifle and are not compatible; the OBR has MOA cant built in and the PST gas block requiring a different design than the PredatARs longer handguard without MOA cant. Additionally, the upper to handguard interface is different between models.

What is a good hand load for your rifles?
Because we are a business and to avoid liability issues, we do not offer advice or technical specifications on hand loading.

Does LaRue offer gun smithing services?
We do not offer gun smithing services nor do we provide assistance or advice on anything that could be considered gun smithing. If you do not have the proper tools or knowledge then we recommend that you seek a qualified gun smith.

What length handguard do I need for my AR15?

Handguard length depends on barrel length and what length gas system your AR15 has.

· Carbine length gas systems will use a 7.0 rail to keep the fixed FSB
· Mid-length gas systems will use a 9.0 rail to keep the fixed FSB
· Rifle length gas systems will use a 12.0 rail to keep the fixed FSB
· For longer rail use, install a low profile gas block and then run a rail as long as you want.

What scope mount do I need?
Scope mount choices depend on a couple of things. First, what diameter is your scope? Scope rings are available in 1", 30mm, 34mm, and 35mm.
Secondly, what is the eye relief of the scope you are buying? Scopes that run in the 3-4" range installed on most AR platforms we generally suggest that a cantilever mount will be ideal. For bolt actions, as well as our OBR platform, and in some cases, shorter eye relief scopes, an inline mount is most ideal. Additionally, scope height over the rail options can raise or lower your scope to suit your needs.

What magnifier mount do I need?
The LT755 series of mounts allow you to mount a 30mm magnifier at either 1.5” with the LT755-30S or 1.725” with the LT755-30T. The LT755-30T will properly align with the following LaRue mounts: LT150, LT129, LT660, and LT659. The LT755-30S will properly align with the following LaRue mounts; LT659NV, LT660HK, and LT751.

The LT755-S-EO designed to mount an EOTech 3x magnifier behind an EOTech with a 7mm riser installed. It places the centerline of the magnifier 1.725” above the top of the rail and is meant to be mounted to the flat top behind the optic.

Which Aimpoint mount should I buy?
The LT129 is our cantilever Comp M2 mount.

For the T1/T2 series, our LT660, LT660HK, LT661 and LT751 mounts offer a variety of height options. The LT787 allows you to mount your T1/T2 on your scope, while the LT724 gives you an offset rail mounted option.

The LT659 is designed for use with the CompM4 series.


Which ACOG mount do I need?
If you have a fullsize ACOG (TA01, TA31, TA11, TA55) use the LT100 ACOG mount, or the LT681 ACOG mount if you are trying to get your ACOG further to the rear.

If you have one of the 6X ACOGs (TA648), use the LT644 mount.
If you have one of the compact ACOGS (1.5x, 2x, 3x), use the LT105 mount.

How does the LaRue/VTAC sling attach to my rifle?
The LaRue/VTAC sling is equipped with QD sling attachments on either end. It will plug directly into a QD female adapter in the front (or our front sling adapter), and plug directly into the QD female adapter on your stock in the rear. If you do not have a rear QD female adapter on your stock, you can remove the QD sling swivel, and weave the sling through the stock like a traditional sling.

How well do the LaRue mounts repeat zero...is it OK to remove my optics from the rifle?
Mounted correctly, you'll have no problems. Repeatability is the heart of our mounting systems. Our mounts have been tested to no more than 5/8” shift… at 1000 yards. That’s around 1/16” at 100, so we can’t tell the difference from taking our scopes on and off since we aren’t shooting groups smaller than a 1/16” anyways.
