5 Great mod for the MPX
Posted by John l on Mar 3rd 2023
Love this hand guard for my MPX, although my only gripe is that it doesn’t go on as easily as the OEM, and made it hard to put the front pin back in on the lower.

5 Midwest Quantity
Posted by Konnor W on Dec 5th 2022
Bought this on black Friday sale, and couldn't be more impressed. Fit is close and tight, no play in rail to frame when installed(factory rail had very small lateral movement). Included picatinny rail piece is nice little bonus. Overall couldn't be happier I can say for certain that the hype and recommendation from other mpx owners is legit.

5 10.5" MPX rail
Posted by Kyle on Nov 10th 2022
I bought an MPX K version. I have a Dead Air Wolfman and asked them if it would fit. They said yes so I jumped on the opportunity. This rail is perfect and the Wolfman fits in perfectly. Sticks out about 2 inches (if that) in the full configuration. Rail was perfect. Looks great. Highly recommend anything Midwest Industries.

Ordered the wrong length and returned it for the correct length. According to UPS the return was delivered 2 days ago, I am currently waiting for the verdict on accepting the return.

Posted by Daniel B on Aug 18th 2022
Such a great handrail , it’s very well finished and continues the top rail seemlesly . It has plenty of room for a supressor I use a hybrid silencerco and there is room to spare . Great purchase overall
