Fantastic BCG

Posted by Joshua Sylcott on Oct 11th 2022

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.
