Which Non-Folding Rear BUIS?

AR/M4 AR Technical Discussion

I am currently putting my SBR together part by part and I need suggestions. In its initial configuration it will be the most inexpensive and required only parts for a functioning gun. The lower is a Sabre Defense with Stag/CMT LPK and stock (for now) w/ H buffer. The upper is a 10.5" LMT with standard handguards (for now). I will be getting a LMT BCG and PRI Gasbuster charging handle (I think). The last thing I need is a rear BUIS. At some point down the road I will put on a rail system, probably Troy 10", maybe a red dot, a flashlight, and a CTR w/ upgraded ismi spring. With not having a scope, I will be using the iron sights and really do not have the need for folding ones, plus the non-folding ones are cheaper.

So the qustions is which one, out of the LMT or LaRue, is better? I know the LaRue is cheaper. Is the LMT worth the extra money? If I could get them both for the same price, which one would you get?

Thanks in advance.

The LT has the lever on the right side, this makes it easier IMO to manipulate the charging handle.

I would get the Larue and put the cost difference towards paying the extra for the same-plane rear aperature.

Larue. Simple, compact, tank tough, leaves the charging handle clear, no BS useless elevation complications.

+1 LaRue

I’ve got a LMT BUIS on my LMT 16" carbine and in my opinion it’s overkill, it weighs more than the LaRue and I don’t really use the elevation of my LMT BUIS at the close ranges I use it.

I also agree that the LMT BUIS have a large mounting thumb screw on the left side which interferes with the CH, it could be changed to a smaller profile fastener but it’s still too close to the CH, not a problem with LaRue.

I’m just going to use my LMT BUIS on my next 20" or 18" rifle project.

Or just chop down a carry handle if you’ve got an extra one laying around you don’t use.

Larue is preferable, but by a wee bit.

I have a few cut down carry handles if looking for an inexpensive solution.

LaRue’s BUIS is robust and very well built. I love mine. Nothing to flip up when the optics go down.
