I just this week finally got around to topping off a .450 for this coming deer season. Wanting a side charger, I had been watching uppers for a while. Out of stock, in stock. Full price, on sale. Etc., etc. from BCA. I looked at Midway, at their AR Stoner brand. Lo and behold they had what looked to be the exact same upper. The side charger had the exact same shape. An identical forearm. Same flash suppressor. Everything. In stock. AND $30 cheaper.
I would be willing to bet that saved $30 that it was built in the same factory. Or at a minimum, with the same parts.

ETA- No issues with it so far. Perfect function with full power loads. But doesn’t like SubX.
