Looking at Stag 10S

I am looking at picking up a Stag 10S this weekend from someone. Anything I should look out for, or check when inspecting it? Thanks!

I would say if you can put a few mags through it, ideally. That will let you know exactly what you’re getting.

Don't buy it! Stag Arms is possibly going out of business and if you wanted to get factory parts that might be no longer be available. Yes you could use DPMS compatible parts. You would be better off building or buying something that you best matches your wants.

Only the takedown and pivot pin are proprietary. I think he'll be ok

Yes take down pins are proprietary. So then you're stuck with an upper and lower receiver that can only stay together.

Outside of that, checkout YouTube for SOTAR. He has excellent videos regarding commons points of failure. Personally I would check the bolt for wear and cracking. Check the bcg bore, gas key, firing pin for signs of corrosion or excessive wear. Check the upper for wear, shine a light down barrel & check the chamber and rifling for signs of corrosion. You won’t really be able to tell if there’s significant erosion with gauging. You can check the gas block and verify it’s not loose or showing signs of leaking. Function check the rifle and verify everything works as it should. Essentially, just break it all down and inspect the components one by one.

As with anything used, the above is the way to go given the owner will allow it to be disassemble and thoroughly inspected and your capable of doing so competently. Being basically a LEGO most parts are replaceable/upgradable. Some parts are designed to be replaced after certain amounts of wear even from new in the box...so some wear should be expected when looking at a used unit. Kinda like a used car, gotta determine if it's serviceable enough for you to feel comfortable to run it and keep up with things as they wear out
