Pros and cons: M-LOK and KEYMOD vs PICATINNY Mil-Std-1913 RAIL

The handguards used on Bob’s Tavor are the TAVOR XL Keymod Handguard from Midwest Industries.

The model used on Mark’s AR-15 is the SSM M-LOK Series One Piece Free Float Handguard. Super Slim Free Float Handguard.


M-LOK is a modular locking accessory mounting system that is a direct attachment method for hard mounting accessories to a negative space mounting point. Designed by Magpul Industries as an evolution of the MOE slot system used since 2007, the M-LOK system is being released as a free licensed platform to allow greater compatibility of accessories between all manufacturers.

KeyMod is a universal interface system for firearm accessory components designed to be superior to the MIL-STD-1913 accessory rails. The concept was first created by VLTOR Weapon Systems of Tucson, Arizona, and released through Noveske Rifleworks of Grants Pass, Oregon, before being published in the public domain for adoption by the entire firearms accessory industry

The Picatinny rail also known as a MIL-STD-1913 rail, Standardization Agreement 2324 rail, or tactical rail, is a bracket on some firearms that provides a standard mounting platform for accessories and attachments, similar to the Weaver rail mount.

  1. vhs beat out beta because the porn industry went with vhs. so….magpul is the porn of the gun industry.

  2. Nicely done and well put good information thank you and nice safety tip at the end.

  3. I’m not really a magpul fanboy but mlock looks so much better the that hardware store rack looking mess of a “key lock”

  4. Carried an m4 for three years in the military, including 9 months in Afghanistan. I never had any of those cons with the picatinny rail system. Lmao ? ?

  5. I remember this guy from Rokon World and the West Virginia Hillbilly Romps. Hey Mark, remember getting the K9 treatment in corrupt Garret County Maryland? I remember you mentioned that your duffle bag stunk from all the WV mud and sweat and the jack boot didn't want to get his hands dirty, lol.

  6. "What's the downsides?"

    "The edges of this are sharp!"
    This made me laugh. I know the pain, but damn- really?

  7. The edges are sharp,WOW,that’s definitely a dealbreaker drawback.I guess in the future I won’t buy anything that has a sharp edge.I might get an Owie on my hand.?

  8. "Invest in rail covers" lol. Cause they're SO expensive. Xp honestly, I think they're playing up the problems with pic rails. The only real benefits I see to going with M-LOK or keymod is maybe weight savings. Even that is kind of a non issue in this case.

  9. Yep you guys have some Skippy audio. But I do agree that M lock looks cleaner and more manufacturers are leaning towards the M lock design. Thanks for the video, first time I have seen a head to head comparison of mounting systems.

  10. You can look at STNGR handguards and they have both key-mod and m-lok in all their variations. Prices are exactly the same. That being the case, choose what you like better.

  11. Any other men here have problems getting their nut to spin 90o degrees? ( Not real question, stupid nutsack joke)

  12. magpul rail covers suck and thus far most of the other m-lok covers are not even close to keymods with noveske covers (yes they suck to put on to some extent, but once on they stay). now that being said magpul other products are usually pretty good, but they have no grip on grip design

  13. Your cons with picatinny.. In the danish army, rail guards are standard issue to protect the rails (and hands). Weighs basically nothing and doesn't take up much space. Actually it's really nice because the rail guards are soft, so you get a really nice grip. Plus it's good to hide wiring for your aiming laser inside the rail guards.

  14. I'm running the cheese grater on my AR-15 for the simple fact that I've been through the others although I did enjoy my Magpul and guard I still went out to buy rails now one of the things that you forget to mention is if you don't secure your rails they will fail also the fact that whatever you install on to these rails still has the possibility of getting stuck on your seatbelt chest gear Etc once again for me the cheese grater is all one piece well to you have a bottom and a top but what I mean to say by that is there is no other parts you don't have to worry about your rails falling off and in the life and death situation you don't want to worry about little things like that losing an optic alike a grip could be detrimental to your situation or frustrating at the range it also depends on what it is that you're looking to run on your rifle I remember back in my BMX days I wanted a 3-piece crank and found that I was always losing bolts and on my one piece crank I really never had that issue but they were still pedals to get caught on whatever regardless of whatever crank I used which is the same what the handguard that you use my quad rail is Troy with an afg and on the top I run my laser light by sightmark depending the situation on my run an in-force wml and it's nice to have the rails that don't fall off and that's my opinion thank you great video guy
