No, this fits to a delta ring style handguard with circular holes.
Yes, standard plastic handguard with regular circle holes, will fit this vert grip...
1: This isn't designed for m-lok or key-mod, it's actually designed for 'standard' type handguards. As in the 'round-plastic' style ones that usually come on 'budget' minded AR-15s. You might be able to fiddle/modify this a bit to work with mlok/keymod, but I would just buy something intended for those systems... This works great for what it's made for, I have it on one of my ARs and am actually waiting for another one to ship from optics-planet so I can put it on that one as well...
2: The width is about 1" it goes well with the standard handguard, doesn't look weird or anything.
Now I used a little blue loctite on the threads of mine and snugged it down pretty good, no wobble or flop from it. I did end up cutting mine down though, shortened it up a bit so its more of a stubby hand-stop and it works good. I never bothered with using the storage feature anyway, but to each their own...
It is not for keymod. Unfortunately, the manufacturer does not have the length listed. We recommend contacting them for this inquiry.
