MLOK was developed because Magpul tried and failed to implement KeyMod in Polymer designs (Eric Kincel predicted this failure). MLOK can be made more quickly and is easier to get right from a CAD/CNC standpoint. Keymod is superior, but it also more difficult, more timely, and (ultimately) more costly to manufactur properly. What about you? Do you have a preference? Hit the comments below. While M-LOK is clearly outselling KeyMod among those who were willing to share, none of the manufacturers indicated that they intended to discontinue sales of one system or the other any time soon. Sales numbers alone can’t tell the whole story but they can obviously play a huge role in manufacturers and retailers deciding which system to continue supporting. There are other factors that can drive sales like ease of manufacturing (and cost), marketing, and more. This certainly won’t end the debate and it shouldn’t because sales numbers don’t mean that one is truly better than the other.

It was interesting that two small retailers that I spoke to shared the sentiment that they tended to order heavy (or exclusively) M-LOK because they have limited cash for inventory and that is what sold better for them. I heard from several others manufacturers who had more anecdotal information (all pointed to M-LOK as the better seller) or that didn’t really want to share their numbers.

Parallax Tactical offers a full line of hand guards with both KeyMod and M-LOK option for retail and OEM.
