Most Helpful Negative Review Tighter fit
The quad rail for the benelli m4 fits but some light 'smithing'is needed to have it squeeze on the magazine tube and barrel. The little lip piece that faces the stock needs to be shaved off for the 2 pieces to fit inside the foregrip catch. Other than that no issues firing or mounting lights, lasers, or pistol foregrips.

Fitment issues

by Ry, Verified Owner from LA, United States Written on June 30, 2024
Will need either a Dremel or some hand files to get it to fit properly, polymer is pretty durable based solely on how long I had to file it to get it to fit, overall if you don't wanna spend over 100 bucks on a better forend get this and expect to spend a couple hours filing it or 30mins with a dremel
Pros:
  • Grip placement affordable
Cons:
  • fitment
Would recommend: No

Wish i had read the reviews first

by D, from MI, United States Written on January 19, 2024
It doesn’t fit. Not only does it not join at the base of the receiver, but the factory magazine tube won’t fit through AND the way this hand guard is made, the pistons on the ARGO system won’t run because of impingement of the poorly manufactured part. Sure, I could spend some time machining it but it’s not worth it imo.
Also; NOT 922r compliant

Chinesium junk. It does not fit.

by Russ, from CA, United States Written on June 7, 2022
Don't waste your money on this piece of garbage. It goes right into the trash for me. The only amazing part of this product is that the Chinese know how to spell "Made in Israel". I tried the Dremel shaving thing. But here's the catch: It is the absolutely worst part of the weapon no matter how you look at it. There are better ways to mount a tac light than to rely on this amateurish toy part with your life.
Pros:
  • "Israel" is spelled correctly.
Cons:
  • does not fit
Would recommend: No

FAB M4 foregrip

by Bonked, from NH, United States Written on October 19, 2021
It is relatively affordable, looks and feels good and the light mount rail is perfectly positioned for my setup. I also had to do some plastic smithing to get it to fit. At the muzzle side where the sides meet, rounding the corners a tiny bit makes it easier to insert into the barrel flange. Most work was done on the inside of the flanges where the go into the frame. I whent very slowly as to not take too much polymer off and make it loose. It has stayed very snug. I like the grip comfort particularly with the PTK angled grip. The top rail is not even with or level with the M4's rail which is not a deal breaker for me as my scope mounts to the main rail and M4 has iron sights built in.
Pros:
  • Price, comfort and convenient side an bottom rails.
Cons:
  • Lack of fit quality
Best Used for:
  • Looking good, being a wannabe, putting a light on the side.
Would recommend: Yes

Fit Issues

by Bob, from MD, United States Written on May 10, 2020
Great idea. You have to modify the hand guards with a drimmel tool to shave down the collar so that it will fit properly. It came with an Allen key that was the wrong size for the bolts that hold it together.
Pros:
  • Great idea.
Cons:
  • Poor Manufacturing
Best Used for:
  • na
