Odin O2 Lite Handguard Connection Interface

[Lastrites]

I have an O2, though it is on an upper that was pre-built. I have removed the rail when I went down the rabbit hole of applying a camo paint job but I never removed the barrel nut. That said the adaptor was solidly in place being held by the nut, so yes it is secured at this point. The rail screw holes line up nicely and the rail has a tight fit to the adaptor. The rail screws are short and they don't have the length needed to reach the barrel itself, again the adaptor is not loose if the barrel is properly torqued to 40/60 lbs. Do apply 1 tiny drop of blue loctite or vibra-tite type of product to each of the rail screws.

It's a nice light rail that seems stout enough for my use with decent ID clearance.
