5 Extended Carbine Version
Posted by Paul Mazon on Dec 2nd 2024
For a very long time I had a very sad LWRCi upper sitting around because of, well, reasons. Enter MWI, with this handguard. I will admit I didn’t read the fine print and it took a bit to get this installed, but once I did, and I got to the range, it was truly a pleasant experience. The LWRCi upper chugged along (it’s the piston type, not the DI type even though I know technically….yada yada), even with low powered Tula ammunition. Seriously, zero issues, it was amazing. Accuracy seems fine, i was only shooting iron sights, but being able to hold the handguards and not have them melt my hand was nice. Good quality, and if you take your time on the install, it won’t be too bad. Remember to remove the delta ring, the spring, AND the front metal retainers for the old handguards. Thanks for reading, thanks for good kit.

I've still been waiting on the correct barrel to install, but overall just holding it and looking it over the fit and finish is fantastic

5 Best rail for fsb
Posted by Kasey on Jun 3rd 2024
This thing is awesome. It installs easy especially if you use a GI barrel nut without the delta ring you don't need to cut it off. I love the look and my deball holds zero. I will definitely be buying more I prefer the fsb instead of a low pro gas block

Great option for upgrading your two-piece hand guard. Instructions were easy to follow and the quality is great!

changed this out for my m4 carbine police style handguard. fit great on my M&P 15.. after I had to grind down the QD on the bottom of the gas block. true free float after that.

5 MI 2 Piece Free Float MLOK Rail
Posted by Ken Rauch Davis on Dec 28th 2023
I have this mounted on a home build using an FN 14.5" midlength with FSB. I aslo have a Centurion C4 Picatinny. Both work as advertised, with the MI being a little cheaper. Very easy install using the stock barrel nut. Would buy again for a future build. Only criticism is not utilizing 7 sides with MLOK. Would also love to see an extended midlength.

5 Excellent Customer Service
Posted by Darrell Sanders on Dec 24th 2023
Kelly was amazing, I inquired about the handguard, and Kelly had it shipped within minutes. It is just as described, replacing my quad picatiny rails. Took about 5 minutes to install.

5 Two piece free float middy rail
Posted by Ken P on Sep 26th 2023
BOMBER MODIFICATION! Well worth money and better than more expensive competitors. This is my 3rd rail from Midwest and always impressed. Install was easy unless you’re a democrat then just take to gunsmith.
