How tight is the lockup on this?
It’s obviously not an LMT monolithic upper, but it looks like that’s the sort of idea that LaRue was imitating. Curious how close they came.

I can try to get you some pics of both the upper and rail if that would help. I have the 13" mlok version, with a 16" Stealth barrel.

I appreciate it.
Mostly, I’m curious about the strength and stiffness of the handguard/receiver lockup. Others have used LaRue’s standard handguards with vociferous praise for its laser and night vision usage potential. This upper and handguards would allow one to mount straight across the mating surface...but not sure if that is a good idea.
They seem to lock up pretty solid. There are two pins that help align the upper and hand guard, then there are 4 bolts that hold them together. It creates one continuous upper rail and as you said you could mount something across them.
Wanted to separate them for you and take some pics but can't find my torx key at the moment. Will add some pics of what I could get for you.

Sorry for the delay with the pics. Once I find my torx key I'll pull the hand guard off and take pics of both sides of the mating surfaces. Found some older ones from when I was building it by the pics aren't very good.
In one pic you can see where I was able to place my scope mount across both the upper and hand guard.
Also, just in case you didn't notice, the keymod and mlok versions are slightly different. On the keymod the bolts are recessed into the mounting flange. On the mlok the bolts a little longer and show outside the flange like mine does.

Thanks for the pictures, that is helpful.
I wonder what the engineering gods of the forum have to say... looks secure to me.
Bumping this thread. This seems like it's a good alternative to the LMT MRP series and gives you more barrel options without needing any kind of custom work. How has this been treating folks who have them?
Does anybody know the total weight of the 13.0" variant, including barrel nut?
UPDATE: According TOS, the 10.5" M-LOK weighs 20.5 oz. and the 10.5" KeyMod weighs 19.4 oz.

Not that big a deal, my out door range I go to is looking to be closed till at least the 31st and I swapped scope mounts a while back so it's not properly zeroed.
Will give me a good excuse to make sure I put locktite and tightened the gas block set screws good enough.
As I said before I have the 13" rail and I have a 16" Stealth barrel. Muzzle device is just an A2 flash hider.
