My range buddy got his from a different site and paid $20 more. Same product. He’s ordering from here next time.

Been in the market for a while and finally decided to buy from Americans Gun. I was comparing this against similar products from eBay and decided to take the chance. Glad I did. Arrived in 5 days, well-packaged, and the quality speaks for itself. Installed it on my G19 Gen3 and ran 146 rounds through it without a single hiccup. This is the real deal.
