excuse the fact that this photo was taken on my bathroom floor I do a lot of gun cleaning in my bathroom for some reason. Feels odd cleaning guns in the dining room when everyone else is home.

I recently picked this up from a local forum for 800. Am wondering if anyone can give me a bit of information as to what I purchased - I see it says McKay on the receiver. It looked completely unfired inside when I purchased it. It would not run more than 2-3 rounds before a malfunction. I have since taken a mallet and my feeler gauges and adjusted the top cover gap as it was touching the bolt and now it runs through a mag or two between malfunctions

What do these go for nowadays? I’ve already gotten it sbrd and ordered a shorter barrel as I plan to keep it even if just as a display piece am just curious
