Most Helpful Positive Review Great for metal mlok - not for poly mlok
I use these on a AR 5.56 pistol and a KS47 7.62 rifle. They install and remove with ease, and don't fall out during shooting. I find the texture to be just right, and they help a lot with heat. I tried them on a magpul AK47 hand guard and they fell out during shooting because the slot covers don't go deep enough to catch and lock on the inside of the thicker plastic. I've ordered three of these and will get more. I have only used the black ones and they really look like original equipment when matched with black metal floating handguards.

Best m-lock cover for the price

by Timbo74, Verified Owner from WI, United States Written on March 28, 2025
I know these are NC Star, which usually equates to junk, but this is a good product.
Good grippy texture. Secures easily, and solid. Aesthetically pleasing.

Nothing to complain about.

  • price construction quality
Cons:
  • None

Good Product!

by Dale, Verified Owner from FL, United States Written on September 19, 2024
These protect your hands and if you mix the colors, they give a sort-of camo appearance without painting your gun.
They install easily enough. I wish they were a little more secure. I don't know how much rough use they can handle w/o falling off. But I like this product so far.

work great

by DS, Verified Owner from MI, United States Written on February 3, 2024
They install easy and they feel durable. Excellent grip, nice rough surface and good coverage. I have only shot around 60 rounds with them on my rail. We will see how they hold up with more rounds.

Rail Cover - 1/2 MLOK Covers

by Legal Eagle 7, from TN, United States Written on October 24, 2022
I love these little covers that take up 1/2 of an MLOK slot. These are perfect in appearance and makes gripping the handguard comfy. I've use Magpul and Ergo covers in the past. I upgraded to these little covers and now everytime I'm at the range, fellow shooters approach me to ask what they are and where did I find them.
Pros:
  • Easy to use & Light Weight
Cons:
  • Price $$$
Best Used for:
  • Radian Model 1 Handrails
Would recommend: Yes

Strong grip, nice look

by Rob the independent semi-liberal moderate, Verified Owner from WI, United States Written on February 8, 2021
Vism M-Lok slot covers instantly became my go-to M-Lok cover solution. I previously had tried Strike Industries M-Lok Covers. These covers can still fill half of a M-Lok slot if the other half is used by something else like a picatinny rail section or QD sling connector. They are also capable of filling a half-slot on a handguard, which some handguards have at the fore or rear, unlike whole slot M-Lok covers.

The grip on these is INCREDIBLE. If you don't have working man's hands, these might not be comfortable without gloves. They are ROUGH.

Additionally, their aesthetics are fairly pleasing. I think I might prefer a slightly more matte finish, but given the rough texture, it's not a problem. The hinge pins are slightly more visible from the top/bottom of a slot than I expected, but it's not enough to detract much from the look.
Pros:
  • Easy to install
  • Intuitive
  • Great grip
Cons:
  • rough on soft hands
Best Used for:
  • Decoration
  • Grip
Would recommend: Yes
