Get the right tools. - Trinity Force Echo Series Free Float Keymod Rail

This is a very sturdy and light weight piece, but not noticibly lighter than a standard quad rail and aluminum barrel nut of the same size. Took a few tries to align correctly, as trying to torque it down with an 1 1/4 wrench with torque hole made it awkward and inaccurate to align. After the 3rd fit-up and screw session, I went with the “I guess it’s close enough” and then saw that the rail was larger than the rail on my upper, and ended up just drilling the screw holes on the hand guard a little larger so I could shift it, then tighten. I’m no master armorer, so maybe someone with more than 7 years experience can do better on the first try.
