Tis’ a golden age of riflery when one of the hardest decision when building an AR rifle is to choose between KeyMod or M-LOK. Not content to force a choice, Midwest Industries has released their M-LOK to KeyMod and KeyMod to M-LOK Adapters.
The adapters retail from $21 to about $25, depending on the configuration chosen. They are available only in black anodized aluminum.
The Gear Locker has one of the first videos on the new accessories. In short, they work.
