Not FDE, but good otherwise

by -

When I opened the box I was disappointed to see that the color FDE is nothing like in the picture. I swear these things are actually OD Green, so much so that I was about to contact customer service thinking I was sent the incorrect product. However, the package barcode does indeed say it is the FDE panels.... Trust me, they look nothing like the picture in terms of color. Besides the disappointment in color, the quality seems pretty good and I like the way it feels in my hand installed on the rail, definitely provides more grip and is aesthetically pleasing. Just wish the FDE was actually FDE and not OD Green.... but perhaps it was a manufacturing/packaging mistake.

Just what my hand guard needed.

Great Product

I have used SBI grip panels on a number of my AR builds. The texture is just right, they handle the heat well, and they look great. But the thing I like most is the quality control, every package has fit perfectly, the colors are consistent, and the T-nuts work exactly the way M-Lok hardware is supposed to.
Thanks to Josh and Henry for a great product!

Slate Black Rail Panels

Picked these up to mount on a Geissele Mk8, and damn they look good. They actually elevated the feel of an already phenomenal rail. I plan on getting more for some of my other MLOK rail systems.

Top notch!

I have several sets of the Slate Black Industries MLOK Slate Panels and they are hands down some of the best rails covers out there. They do very well at keeping your support hand from getting scorched during high rates of fire and they have a nice grip texture. I have six uppers with MLOK rails of different varieties, and they all have SBI panels on them. Try them out, you won't be disappointed.

I like them

I have these on a bunch of rifles. I do not like front grips and such. These work great.

Love them

Great way to add some comfort and grip to your empty m lok slots without breaking the bank. I have these in black and fde for different builds and not only do they serve a function but they also look great.

Good quality, Not FDE.

Have a set of the black ones on my AKM. Fit and feel is great. Bought the FDE to go on a burnt bronze cerakoted AR. The color is more like a chocolate brown. Will keep them, just going to paint them closer to the color I'm looking for.
