Reviews & Ratings for Firefield Fringe 15" Carbon M-LOK Rail FF34072 — 2 reviews — Page 1

This Product is very light not very strong it flexes out at the end. The one that i got shipped to me was crowned not flat it hit my barrel in the middle.
It felt like it was made out of plastic didn't have the carbon fiber look or feel

This handguard says it's made with a "carbon-fiber composite material", however it really feels more like it's polymer. That's fine with me, if it is up to the task. So the question is, is it up to the task? Yes and no.

This handguard is SUPER light. Which is a pro if you like to lighten things up. Because it is polymer/carbon fiber, the handguard does flex if you put pressure on it. It's not horrible, as it will always spring back to original shape, but keep in mind this is nowhere near as rigid as aluminum (which also flexes from pressure too, by the way). The flexing is not an issue when holding zero though. I put some quality steel iron sights on this handguard, and it does hold zero.

However, because it is polymer and flexes, there is a problem if you overtorque the handguard onto the barrel nut. I probably did that with mine (there are no specs as to what sort of torque rates to apply in the instructions). It must have overtorqued the rail slightly vertically. Currently I have my front iron sight bottomed out and it is still hitting an inch too high at 50 yards. But it holds.

I think that's the major design flaw, as nothing is preventing the handguard from warping when you tighten the rail to the barrel nut. If they changed the design and had the rear be aluminum and then 3/4s of the rest to be the carbon-fiber composite, I think that could solve the issue.

Barrel nut is aluminum and not steel, for what it's worth. I don't mind it but be careful not to...
