Awesome Rail! 5/5
This rail does the job! Glad I picked it up for a decent price at Brownells. I’ve been looking for a quality mlok rail and a lot of people said to get a Midwest Industries. I picked this one out and it has exceeded my expectations. The rail lockup is snug and there are plenty of points that support various mlok attachments. I really enjoy the qd mount that is built into the rail. Glad to be supporting a company that makes their products in USA!

Perfect fit and finish
I recently purchased the Midwest 14” G4 hand guard for my SFAR RifleSpeed gas block upgrade… The fit and finish worked perfectly and the instruct made the job quick and easy from start to finish.

Good to go
Easy to install. Love the barrel nuts that don't need to be timed. Just thread it on and torque it down and you're good to go. Handguard fits really snug over barrel nut, which I like. Overall very pleased with this for the money.
