This is not about what torque should be on the barrel nut or RE.

This is about: Do the pieces/parts, that we put on our rails (I.E. BUIS, light mounts, lasers, etc...) have an assigned torque setting?

If they do, does it differ between manufacturers, parts and places mounted?

I always hear people say; "Just tighten it down finger tight, you'll be good". Well everyone's tightness is different across the board. Is there a proper setting that should be followed in regards to properly mounting items on rails so they stay put as they should?

I've never had a gizmo that came with a written torque value that I can remember.

I just tighten down real snug with the small allen wrench that (for example) comes with a set of scope rings.

You could buy that scope install torque driver and just hit everything at 30-40 and be fine.

Many rail manufacturers do assign torque value to things. Other things are simply common sense I think.

The size of the screw and the value of what it is holding determines the torque value I use and the type of Loctite. Having a fantastic set of German inch and pound torque wrenches, I go OCD on all screws and always tighten equally (same pressure across the board). This is of course overkill for many things, but is how I roll.

Yes, that is a little overkill (not that its a bad thing.:D) I haven't seen a torque spec on many rail-mount accessories, but I don't use many either, so... Unless you plan on mounting a battering ram for room entry, or a bayonet or something a little blue loctite and tighten with a wrench/hex key(aka allen wrench) is probably enough.

And that's the thing, I've never had any pieces or parts that are screw or bolt on come with a torque setting/requirement. Sans my Larue scope mounts.

You would think that there would be in order for the piece/part to be properly installed and set. At least that's my thinking anyway.

I've got the fat wrench. It's pretty good for what i need it for. I've been going through and hitting all screws at 35 in. pounds. I never liked the Loctite thing when it comes to rail mounted items.

Tight and a quarter (turn that is).
