Thanks for posting but most of what you posted are generic and applicable to many different guns. This posting is specific to MPX only parts. For instance the MCX mount above will work on any Mlok mount system. I would suggest that you consider posting a separate thread regarding how you dressed out your MPX. I’m sure others would like to see it.

Most of the links on this thread are either dead or out of stock, I guees covid effect...
I found 4 links out of 24 on manufactures websites that were no longer linking to the product. But to use the term “most”, now you are exaggerating. Post number 1 is now updated.

I do what I can, but I can’t control when a manufacture changes their website or product line.

Sorry, I can’t help you with out of stock items. Try writing to the manufactures of the items you want and let them know there is demand. That’s what I do.

Perhaps you could send a friendly PM to me if you find a link not working and I can fix it.
