Perfect fit for my 13.7" barrel.

I love Midwest industries rails. They look the best in my opinion so I already knew the direction I wanted to go with my build. The MI 12.625" rail is the best choice for a pinned 13.7" AR-15!

Great handguard for the money

The Midwest handguard Gen 4 is really good for the money. Install is the simplist & easiest of any handguard design. The weight is good, and integral qd sling points are nice. Removing the handguard to clean & wipe down the barrel is easy, and easy to reinstall.
