Product is spot on! Very high quality machining, very tight fit and super light weight. The desert dirt color is a shade lighter than burnt bronze. I was new to the M-Lok system was hesitant to go from keymod to M-Lok now in the process of changing everything I own! 9.5" rail fit perfect on my 10.3" barrel with just enough of the barrel left to mount a direct thread can on with clearance.

Looks great, does its job. You can mount different things out front with picatinny rails on all 4 corners. Dont understand those 1 star ratings. Overlook them for sure. Geissele is top notch as always.

I received this handguard, with small minor scratching near the front of the hand guard.I was willing to overlook that as I’m sure it won’t be pristine forever.That being said, when I attempted to wrap up the install, that’s when I noticed it was missing the set screws required to finish the installation.I thought this was supposed to be a quality piece. Apparently, that just hype.

You can’t go wrong with Geissele rails, especially when it comes to the MK4 line. They are solid as a tank, lightweight and dependable when it comes to sight accuracy.

This rail looks really good and feels good. But does not comes with the gas block in the picture. I wish I would’ve said or give a warning that it didn’t come with it so I would’ve bought it when I bought the rail. So now I have to order a gas block and wait for it. Also the problem is that in the question for this product it said that it came with a gas block and it didn’t so.
