Yes, my friend, the fit is identical! And you could have this exact B-3 depicted here with a few keystrokes on our website. Also just arrived are some fabulous Rough Wear 17756 B-3's and .50 CAL. versions. The .50 CAL is selling fast due to a TV show that bought a lot of sizes in multiples across the range in the B-3 and B-6, but we still have all sizes as of right now. Please let me know if you need anything else at all. Thank you!
