Reviews & Ratings for Geissele MK16 Super M-Lok 13.5in Modular Rail — 10 reviews — Page 1

First off, the packaging was completely crushed when I received it and it looked like it went through a tornado. Fortunately, the handguard was still intact but I was not happy to see the state of the packaging when I first got it. After using a can of air to blow off all the cardboard particles that collected within the rail I went ahead and installed it. I have a Geissele barrel nut wrench so there were no road blocks for me to get it installed right away. I went to torque down the barrel nut which is made of 7075 aluminum and was surprised how fragile it really is. As I was torqueing the barrel nut down the the torque wrench started to slip and it bent one of the holes in the barrel nut. Thankfully, the barrel nut comes with two holes so I flipped it around on my Geissele reaction rod and finally got a good grip and torqued it down to spec. My OCD got the better of me and I reached out the Geissele to see if I could buy a new barrel nut for his handguard. In the meantime I will use the barrel nut that it came with even though it is partially damaged. Outside of the crushed packaging and damaged barrel nut, the handguard itself is fantastic. Super tight tolerances, nice fit and finish, easy to install as there is no timing involved and easy to get the handguard on the upper. I got it perfectly aligned using the mounting hardware and anti-rotation tabs. I really like the steel reinforced sling QD mounts and how it has 7 sided M-Lock slots. It's pretty lightweight as well.

Very well made, just keep in mind shades can run from desert to bronze.
If your good with that its a great upgrade.

Great quality always received from geissele.
Only issue is inconsistency with color. In the past always good, darker tone compares to burnt bronze now.

Great hand guard, highly recommend and Optics Planet has fast shipping.

I love this rail! This is my 4th build and I wanted this one for a 50 shades of FDE build. It’s much darker that expected so I’m going to save it and order another one for a lighter shade.

Love this handguard. Geissele fit and finish is top notch and worth every penny. I saw a review that brought up the lack of Geissele wrench. Tapco and ar stoner have ar15 wrenches have a pin spanner on them as well as a 1/2" drive for torque wrenches.

Top notch quality, as usual from geissele. A little shocked at how orange desert dirt is. Also found that people complaining about the lack of geissele wrench are mistaken. Tapco and midway usa ar15 wrenches have a pin spanner section that works perfectly.

Great rail. Only downside is you need to buy a proprietary barrel nut wrench separately.
