Most Helpful Positive Review Fits and works fantastically.
It took a while to ship, but I didn't have all of my other parts yet anyway. I was a bit concerned about needing to add the adhesive to the barrel nut and still being able to get the hand guard off if needed. It fits very snug and has zero movement without using the adhesive. The torque plate fits p...

Most Helpful Negative Review False advertising
I bought my Midwest GM3 10” believing I was in fact getting a true 10 inch rail. Only to come to find said rail is 10.50. I am building a 10.5 pistol I was hoping going with a 10 inch rail would allow room at the end of the muzzle to attach a suppressor on my Lantac Dragon ASR. I love the quality of...

Midwest Industries G3M Series M-LOK Handguard 15"

by F1fanatic, from NE, United States Written on December 11, 2020
I have two of the mid length hand guards but needed the 15" to cover the gas block on my new barrel. I've shopped for a lot of hand guards but the MI is my favorite. Light, slim profile for an ergonomic feel and good looking.

Midwest Industries G3M 15”M-LOK Handguard

by BanjaxD34, from OK, United States Written on November 18, 2020
It went together like butter. The machining is very nice and the fit and finish perfection I like that it makes the entire barrel length prime real estate and perfect for C-clamp grip makes it easier to drive into corners and control recoil
Pros:
  • almost everything
Cons:
  • Extended delivery time

Nice Handguard.

by LSipe, from NC, United States Written on July 23, 2020
Used this handguard on my AR 9mm build and I think it is great. Pricey but a nice setup. Will use this handguard on future builds. Great name brand. I like the slim feel of it and the full rail all the way to the end.

Pros:
  • Looks great
  • Easy to mount
  • solid
Cons:
  • Mine was scuffed
Best Used for:
  • Any application
Would recommend: Yes

Poor Design/Defective

by Drew, Verified Owner from NC, United States Written on June 27, 2020
Heli-coil threads broke when tightening down handguard clamp screws. I had my Wheeler Fat Wrench set at 50 in-lbs with plans to go up to 55 in-lbs per the instructions but the helicoils broke before the wrench clicked and started to spin without tightening. Was a nice looking handguard and light but that design just feels cheap.
Pros:
  • lighweight
Cons:
  • poor design
Best Used for:
  • Paperweight
Would recommend: No

Light, durable, feels good

by Jezzro, Verified Owner from TN, United States Written on February 19, 2020
Purchased the 10" version for my 6.5 grendel build. I am very pleased with how easy this rail is to install and you can line the top rail up with the receiver very easily. The weight is super light for an aluminium rail. It feels very solid and smooth on the hands. Ive always been a MI fan but this has been the newest version ive puchased in years. The quality has always been good but it became better and better over time. Just spin the barrel nut on and torque. No lining up the gas tube or indexing a certain spot/torque to get the top of the rail lined up.
Pros:
  • Light, durable, easy installation
Cons:
  • None
Would recommend: Yes

Great rail!

by wsmith240, from TN, United States Written on February 17, 2020
I’ve had this rail for over 2 years now and it has held up great. Fits tight and pretty light. After mounting various parts on it there still isn’t a scratch, looks and feels great although I would recommend getting some sort of rail cover or grip for wherever you put your hand as the metal can get hot if you’re running your gun pretty heavy.
Pros:
  • Lightweight
  • tough
  • Well constructed
Cons:
  • None
Would recommend: Yes

M-LOK is on of the best

by Tobias Karr, Verified Owner from WA, United States Written on February 5, 2020
I have switched to only using M-LOK hand guards after having problems with attachments coming lose of completely falling apart. The M-LOK hand guards because of how well built and durable they are. I have not had any problems in the last several years since I switched. The design is well thought of and the look is very good. I even ordered a 12.5 inch upper for my 5.56 that came with a key mod and I ordered another M-LOK just to change it out because I know that once I use it, I wont have any issues.

Pros:
  • Like how its built an it fits the bill for spec
Cons:
  • None

  • Short barrel combat entry weapons
