This here is one of the best budget BCGs I've bought so far. I've fired close to 500 rounds from when I first received it, which isn't a massive benchmark, but considering it's mostly Red Army Standard steel-case .223, it's functioning remarkably well. As for shipping, it arrived well within the initial timeframe with the new upper I also purchased from MWI Inc, so no complaints about expediency.
Overall, an excellent product for the price point, highly recommended if you're looking for a functional and quality-built BCG.
