I am a CNC Machinist by trade, and a Army Veteran, so I know OUTSTANDING Machining and Quality when I see it. Really AWESOME Product!!!! Can't wait to use it on my next build.

Easy install, lightweight, esthetically pleasing and plenty of attachment points. No downside.

Great handguard

by -

Awesome product. Install was easy, no timing of barrel nut necessary.

Solid hand-guard comparable to BCM

by -

While still maintaining a low profile this handguard feels just as solid as my BCM 15" rail on my 16" recce. I'm a big fan of Midwest Industries as they're a good price point for the quality and has the QD mounts on nearly all their rails

Quality of old

by -

The quality of Midwest Industries is that of a machinist of the past. Every corner and mlok slot was machined with precision. It was the perfect match for my 14.5” pin and weld build. These rails may seem a bit higher priced than others however the included barrel nut wrench and ease of install more than make up the difference.
