Midwest Industries, Inc. offers a variety of options when it comes to rail systems. Targeting the average shooter, Midwest Industries prides itself on offering high quality at an affordable price. All of the versions offered are light weight, have T-marked mil std 1913 rails and are made of 6061 aluminum. For those that are wanting to save some money and are able to do some extra gunsmithing; we have our T-Series one piece free floating system that is compatible with most gas piston systems. This option does require barrel removal and the use of a proprietary barrel nut. Another option requiring minor gunsmithing is our two piece free floating systems. Both free float options offer a no gap monolithic look. Finally we have the two piece drop in models. No gunsmithing required, they install just like the factory plastics. All models are available in black, some models available in flat dark earth and OD Green.
