In summary, KeyMod seems to be the top contender for the number one spot in terms of picatinny rail system replacement.

Magpul has everything from polymer rail sections and aluminum rail sections to carbine-length handguards and hand stop kits. Those are but a few of the many KeyMod-compatible accessories being mass-produced today. BCM’s Vertical Grip Short features a tool-less attachment method which makes life a lot easier and other companies like Knight’s Armament offer barrier stops that provide that extra support you need when firing from improvised positions. It easily indexes accessories and those KeyMod accessories are incredible and diverse. It’s never let me down and it’s been around long enough for me to have noticed any substantial deficiencies. While I haven’t had much experience with M-LOK personally, I can attest to the quality of KeyMod’s design. A friend of mine said that M-LOK chewed up the front and rear of the slot where his bipod mount clicks into metal claws, saying that the sharp edges bite into the interior of the M-LOK slats.
LONG KEYMOD RAIL SECTION INSTALL
Some avid shooters have called M-LOK “garbage” on gun forums while others have said that it’s more difficult to install than the KeyMod system.

When they caught wind of the general KeyMod system idea, they wasted no time in producing their own variant. Magpul is one of the biggest names in firearms and firearm accessories.
LONG KEYMOD RAIL SECTION SERIES
KeyMod rails are comprise of a series of “keyholes” which allow the user to attach compatible accessories by lining up the lugs on the accessory with the circular part of the keyhole. Mission First Tactical sell KeyMod QD sling mounts that work with standard quick-detach sling swivels and Seekins Precision NOXs ™ offer an affordable KeyMod handguard with a one-piece freefloating design. A number of companies are now manufacturing KeyMod rifles and handguards along with accessories such as bipod adapters, flashlight mounts and more. KeyMod-style handguards are impressively light and allow the user to directly attach KeyMod-compatible accessories to their rifle. KeyMod is a fairly recent development from the people at VLTOR and Noveske who created it as a public domain design which allows all companies to manufacture KeyMod rails without having to pay royalties for the privilege.
