I'm trying to configure a few uppers, and I've narrowed things down to either an ALG rail, or an MI G3 M-Series rail. I have a V2 that I'll be using on an SPR-type build, but these others are 16" carbines. I'm wanting to put rail covers at 3, 6, and 9 o'clock, and a TLR-1/X300 at 12 o'clock in front of a fixed Daniel Defense front sight. I prefer the mounting system of the ALG over the MI G3 rails, but only the V1 ALG rail has M-lok slots at 3, 6, and 9.

So my question is this: can the co-witness rail sections be stacked close enough together to allow me to activate the light without the DD fixed front being in the way/too far to the rear that I can't reach the light around it? Can anyone who has two rail sections take a photo of them mounted one right behind the other at the 12 o'clock position?

I'm not against other M-lok rail systems, but the ALG and MI systems seem solid, well-built, light-weight, well-priced, and small in diameter so that adding rail covers doesn't make the rail too big around. Sometimes having so many choices is more a hinderance than a help for me, haha. Thanks in advance.

I don't have a X300 or DD front, but, the ALG cowitness rails take up 1-1/2 slots each. So you'll be able to butt them up with no issues, and they'll take up three total top slots. I'd guess you only lose 2 picatinny slots since the cowitness rail has some ergonomical slope on the ends.

This photo of my setup may help with the cover questions. I cut my cowitness rail down so it only takes up one slot. But it only uses one t-nut, which is still rock solid.

Thanks! Sent you a PM with some questions.

The V3 rail would allow you to have the fixed front and the X300 at 12 o'clock just in front of it.

It would, yes, but it wouldn't allow rail covers or other attachments at 3 or 9 o'clock, only 6. The other M-lok slots are offset on the V2/V3.

Check out Magpul's Type 1 rail cover (https://www.magpul.com/products/m-lok-rail-cover-type-1). Those can be used on all slots of the V3 without issue.

You didn't originally mention any other accessories, what else would you need to mount? You could still run rail covers in the slots where they are. The newish Magpul M-Lok covers would work well...

TA2005 linked the covers I was refering to...

I suppose I'm keeping options open. I don't want to have to purchase more gear to switch things around later, but in a way, that's unavoidable. That, and if I wanted covers other than the Type 1, I'd be limited. So at this point I'm just feeling options out before I spend money.
