This MidWest Industries rail systems offers you a great, low price high value AR-15 hand guard.  This hand guard has modular capabilities, is easy to install and has all of the features you would want in an AR-15 hand guard.


This AR-15 M-LOK rail system is free floating.  This means that the hand guard does not contact or interfere with your barrel.  Hand guard that are not free floating can have a negative impact on velocity, as they can interfere with barrel harmonics. 


At 8.7 ounces, including the proprietary barrel nut, this hand guard is extremely lightweight.  This is in part due to the M-LOK negative space mounting system, which saves a significant amount of weight, when compared to the old standard, MIL-STD-1913 Picatinny rails.  Weight was also shed via several lightening cut along the hand guard.  This light profile allow for improved rifle balance and this also acts to allow air to freely flow around the barrel, thereby enhancing the ability of the barrel to cool.


The hand guard has a slim, 1.5” outside diameter.  This slim diameter is extremely comfortable to hold and many users feel that it enhances their control of the rifle. 


The M-LOK accessory mounting slots allow you multiple options when it comes to mounting your M-LOK accessories.  Even if you have Picatinny compatible accessories, the MidWest M-Lok rail has an included M-LOK compatible Picatinny rail section.  This allows you to mount a Picatinny accessory to your M-LOK rail system. 


The top of the rail has a full length Picatinny rail.  This 1913 rail is continuous and mounts up with the Picatinny rail on your upper receiver.  This allow you greater flexibility when choosing where to mount your optic and other Picatinny mounted accessories. 


To allow for easy sling integration, the M-LOK rail has five integrated QD sling sockets.  These sling sockets have anti-rotation capability to prevent your sling from getting tangled.


This M-LOK rail system is easy to mount, but may require some minor gunsmithing.  The hand guard is designed to be installed on Mil-Spec AR-15 upper receivers.
