I don't have details on what exactly they did in that test, but the numbers are certainly significant. There have certainly been tests in the past that seemed designed to favor one product over a nother. Many casual users seem to prefer the keymod system for ease of assembly.But when it came to stress testing the two systems, M-LOK rifles could be dropped on the ground and 100% of the time, the attachments would stay securely fastened to the gun. For KeyMod, however, the success rate was a measly 33%.
Since keymod is open source there is no real guarantee it is all the same. If a company makes parts out of spec they can still sell them.
With Magpul controlling M-lok with free licensing if a company releases hand-guards out of spec Magpul has some enforcement ability.
You could do the ol' picatinny rail, which I'm no longer a fan of. Too much weight added. Some companies have their own proprietary stuff, but I would avoid that at all costs.Are there other options as well?
