Dried cum

Looks like smegma. When was the last time it had a shower?

that's trunion too

one of your roommates/family members jizzed into it.

I just picked up a 1.5mm receiver and it had identical looking dried up cum around the rails. If i had to guess, its some sort of adhesive that held the rails in place prior to being spot welded.
Although. I wouldn't see any reason to put any adhesive in that spot. The top hand guard retainers (or whatever theyre called) look like theyre pressed onto the gas tube, so it could be some sort of old dried up anti-seize grease

There's a lot of heat produced when pressing tight parts into position. Anti seize has solid lubricants suspended in a liquid lubricant. The solids perform better under heat than the liquid. It's basically a 2 stage lubricant. Anti seize is the tits for when you really have a screw you need to torque down on and may need to remove later, just a bit of info that may help you out sometime in life.
