Perfect height, and very nice shape, I remixed it with more slots for my red dot.
Thanks for the design

Glad you like it! We'll check out the remix.

What mounting hardware did you use?

Hey DilllshOn,
We used the magpul AFG hardware to build this around and the file has (sadly) been lost due to a HDD failure so we cannot look up the hardware list at this point. If you print the unit and get the hardware yourself, please share your findings here.

give it a 5% bump in size for a comfortable fit. The hex side of the break away clamp is too small for the 8-32 nuts available. I warmed the nuts with a flame and heat molded the print to accept them.

The other fix was I chopped the hex nut covers off, and cloned the far side round head insert, then relocated the clone rounds to the far side. now it has no issues hosting mounting hardware.

When I designed and printed this, it was designed around the hardware used in a Magpul VFG. I can get you measurements if needed, but it should fit just fine. You may need to break the edges with a file if the print isn't perfect, but I didn't require any heat or permanent insetting to make mine work.

Thanks for the feedback!

Think it's just gonna be the difference between Ace Hardware and that what magpul can access.

I like that you included some aesthetic features to this design. It has a commercial look to it.

I am new to solidworks, can I ask? , how did you do the recessed nut and the thin wall around them? Is it a feature or did you have to do it by hand? Also terminology wise, what do you call these type of "nut recesses" and the "platform/wall" around their edges.

I didn't get a notification about your comment. If you're still curious, after knowing the dimentions and location needed for the nut to be placed, I drew a hex oversized (don't remember the values at this point), extruded "up to next", then cut the recess to the size of the nut plus some for tolerance, slightly deeper than the height of the nut.

Cheers - I'd hoped there was a magic trick to doing this;)

Hello i made one today. But i have a problem with it. The top rail i to short for my RMR sight need 4 "holes" to be mounted propperly. So i wounder if you kan make top rail about 10mm longer. Can post photos if you want
And maybe make overall length of the riser shorter by 15mm since it dont have any function :)

The mount, as designed, matched up perfectly with the Larue mount for the RMR. I, however, don't own an RMR anymore so designing for it would be tricky. If you'd like to tinker with it, I can upload the SolidWorks file temporarily.

Yes i can modify solidworks file for you if you want. have been using that program a lot :) And i have a trijicon RMR on hand now :) My Email is if you want to mail the file.
