Very nice! I had to rescue my 78. I traded a guitar for her at a pawn shop, sporting an ATI Monte Carlo and a metal duckbill mag. Eventually I hunted down everything I needed to get her back to normal, which isn't all that easy to find unserialed. I would say it's my nicest Chinese, these are very well built.
I don't recall whether I ever tried the 20 rounder I have in it. I must say I like yours without the star better, it looks less, odd.
In fact, it actually looks far more appropriate on yours, I may give it another try on that, although I keep getting tempted to sell it due to the insane prices they get....which only seems to keep going up. It's like a big heavy savings bond!
