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.

So far very pleased with the quality of this handguard. A solid upgrade from the original handguard that came standard on the mpx.

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

5 Midwest Industries MPX 4.5in Handguard
Posted by Dave F. on Jan 22nd 2021
This is actually my second Midwest Industries MPX Handguard. I bought the 8in version while still awaiting delivery of my new MPX-K. I liked the 8in Handguard so much that when I finally received my gun, I immediately ordered the 4.5in Handguard to replace my stock one. It looks and feels so much nicer than the standard Sig 4.5in Handguard. The Handguard retainer seems much stronger than stock, which should keep it from loosening up and rattling. Plus I have more and better options for mounting M-LOk accessories like my Surefire Mini Scout Weapons Light. Well done MidWest Industries!
