Most Helpful Negative Review Agency Arms M4 Handguard
I ordered the Agency Arms Mlok handguard for the Benlli M4 and unfortunately, had an issue with the handguard fitting! The handguard would not properly fit the the barrel and loading tube of the gun and wouldn't sit flush with the reciever. This was after following the exact directions Agency Arms p...

agency arms for benelli m4 too loose

by HeyArghhhhh, Verified Owner from CA, United States Written on October 5, 2025
If you google it, you will see others have issue with the hand guard being too loose. Well, guess I got one of those because hit has a lot more wiggle than anyone would want, about 1/8 of an inch up/down and left/right. I contacted the manufacturer, here is a copy and paste in response to a video of the wiggle after I took it off to inspect and reinstall again to their specs. Their response “Thanks for showing us that. Looks like it's installed correctly, but there's definitely more wiggle to it than we normally see. Unfortunately, there's not much we can do to diagnose why that's happening without having the gun here, but even then, we'd correct it by using rubber shims to lock it in place. If you want to provide us with a good address, we'll ship over the rubber shims we use to lock it in. You just need to set them on the back end of the receiver in the slots where the handguard sits in order to create the tension that will hold it steady.” Seems like poor quality if the solution is to use rubber shims to keep it from wiggling. It should just fit. It may be too late, but reaching out to optics planet to return my product given this response from the manufacturer.

Agency arms Benelli M4 MLOK hand guard

by Royce, Verified Owner from LA, United States Written on October 27, 2024
I purchased this hand guard to upgrade the capability of my Benelli M4 shotgun. By far the best purchase Iv made from optics planet. It came in its own protective zipper case and everything. Will continue to give optics planet my business.

Awesome handguard

by Timothy McGuire, Verified Owner from TX, United States Written on June 7, 2024
This handguard is awesome, to put it simply. Low profile and is amazingly well built, it is as tough as the gun itself. After 500 rounds in an afternoon, this thing felt exactly like it did when I initially installed it. Came with a case of all things that I feel would be perfect for a hush can
Pros:
  • Robust
  • Beautiful lines
  • Titanium screws
Cons:
  • Is expensive but it's for a Benelli M4, so who cares?!
Would recommend: Yes

What you need

by HotrodC, Verified Owner from CA, United States Written on April 18, 2024
I wanted to keep the classic look of the M4 but allow for what I needed for my set up. This handguard is sleek enough to not make it look too tacticool especially if you apply some rail covers for the areas you don’t need. Well built and easy to install. Just remove your mag extension tube first if you have one.
Pros:
  • Functional
Cons:
  • Adds weight
Would recommend: Yes

great product

by aznative, Verified Owner from AZ, United States Written on March 12, 2024
Agency always has solid quality products. I love the hand guard on my m4. It feels solid and no wobble or cheap feeling. Optics planet is always fast and ships almost the same day or next day. I’ve been a customer for a long time and will continue to be one in the future.

Will get stuck on 2 piece tube

by Jerry, Verified Owner from ID, United States Written on January 19, 2022
Great product, only slight movements once it’s installed and unlike some other offerings it does not directly make set screws contact the gun itself. Instead it uses a good design which locks into bracket.
However if you have the 2 piece mag tube version you’ll either have to take the tube apart every time on cleaning or buy a new 1 piece tube that doesn’t have the extra thickness.
Pros:
  • One of the best upgrades avaliable
Cons:
  • Wait time
  • needs specific part
Would recommend: Yes

Great fit and finish, only wished it shipped sooner

by MuddyRiver, Verified Owner from MA, United States Written on October 24, 2021
Waited 7 months for this handguard and boy was it worth the wait! Finish and fit are impeccable - haven't attached any mlok accessories yet, but I'd imagine it will be a breeze. Followed Agency Arms youtube installation video and start to finish only took about 10 mins. Great product, would highly recommend as an upgrade to the already amazing M4.
Pros:
  • Fit + finish
Cons:
  • price
  • Wait time
Best Used for:
  • everything
