Most Helpful Positive Review Great item
A good hand anchor placement. I would caution that this will not work on an AR15 using Magpul Gen 3 mags ! There is a travel limit on the Gen 3 mag's rear. This shoulder limit must be removed / made level with the existing back spline. You can avoid this by using either metal mags that do not ...

Most Helpful Negative Review Does not fit M&P 15/22
Will not fit a Smith & Wesson M&P 15/22 without modification. I even messaged Optics Planet before purchase and asked them if it would fit, never got a response but ordered anyway. Disappointed to say the least, now the nightmare of returning it begins. Don't want to attempt modifying in case it sti...

not a gimmick

by vandurabytheriver, Verified Owner from NV, United States Written on August 9, 2026
these things may look gimmicky, but I love them. Great handhold when needed and they look great with the interchangeable faces.
I painted two of mine for a quick and cheap way to personalize.
it is not super clear on optics planet that the grips don't come with the base.. so be aware of what you are purchasing as I have seen many down votes for folks who just purchased the grips without the base Magwell cover they snap on to.

Unnecessarily awesome.

by Bubbacup, Verified Owner from VA, United States Written on April 10, 2026
Do you need this? Does it perform a significant functional service? To be honest, I'd say not on both counts. Is it overpriced? When you add the cost of the replacement mask- most definately. Would I buy it again? HECK YEAH! I got this, the base well cover grip, plus the optional Crusader accessory mask and the combo looks glorious. It's too bad there isn't an option to upload a reviwer photo because you need to see both pieces put together and on a gun to fully appreciate the awesomeness. Purely an aesthetic add-on, just wanted more FDE color on my budget AR without having to get anything Cerakoted, this offered color plus grande personality. Don't try to justify, just buy them.
Pros:
  • Customization
  • Easy to install screw-on wrap-around design.
Cons:
  • Cost for what it actually does
Best Used for:
  • Inciting envy

Mojo Mag Well

by Mojo Mag, Verified Owner from KS, United States Written on January 10, 2026
It's made well but after test fitment it's going take some grinding, sanding, and filing with several trail fits to get my Magpul magazines to work with it. However it does fit better than the older magwell grip from FAB Defense. Never could get that one to work properly with Magpul magazines.
Pros:
  • Made well
Cons:
  • poor fit
Would recommend: No

It's a cool concept, but cumbersome and flawed

by Guy in Pequea, Verified Owner from PA, United States Written on March 26, 2025
I liked the idea of having another area for foregrip, but I simply don't like it. I never thought I'd need something like this, but I thought I'd give it a shot. Some would think it's cool looking, but it does nothing for function (for me). Aside form that, and the most troublesome, was that it hangs up your magazine, and you have to forcefully pull your mag out instead of dumping it! I'm sure this can be rectified with a Dremel Tool or a file, but NOTHING should prevent the immediate release of your mag. I put this very easily onto an FN15, so there was torqueing to get it to fit that might have mis-shapened it, so it definitely wasn't user-error that made it hang up the magazine. Again, this was on a mil-spec FN15DMR2, not some Frankengun that may have a some weird flared/un-flared magwell.
Pros:
  • Neat looking
Cons:
  • Terrible deign for safety reasons
Best Used for:
  • looks only
Would recommend: No

Excellent beyond my ignorance!

by BC1812, Verified Owner from CO, United States Written on February 16, 2025
So I purchased the night, Templar face cover by itself. I was pretty disappointed because it did it fit properly not realize that I needed this piece as well. “Operator Error” Once I ordered this, it made 110% sense to me after that. It feels real nice in your hand with a nice tight grip. It’s like putting Isotonic glove on your mag well. It allows you to have an extra option for grip if needed. I personally like how it easily guides my magazine into the magazine well. Very simple to install and very secure once installed. No special tools are needed to get the job done nor do you need an armor. The material is also very tough. It seems like it could take a good beating. Ensure that you do not have flared magazine well, it will not fit. If you’re looking for a simple upgrade, that is beneficial and good looking, I’d recommend this product. I’m sure John Wick would recommend this as well.
Pros:
  • Easy Insallation
  • Bad assery
  • Astetically pleasing
Cons:
  • none can see
Best Used for:
  • Grip & Stabalization

HAVE TO MODIFY TO FIT AEROPRECISION M4 LOWER

Looks good, feels good, needed Dremel adjustment

by AZgunner, Verified Owner from AZ, United States Written on December 30, 2024
Have an Aero M4E1 lower. Lower mojo magwell inside corners near bottom of trigger guard needed some judicious grinding to fit properly. Less than 15 min. work. Still happy with product.

Cannot be installed completely and beautifully

by J cloud, Verified Owner from TX, United States Written on November 7, 2024
The design is defective, it cannot be completely closed and the screws cannot be tightened. There are no installation instructions in the box. You have to find the disassembly steps by yourself before you can install it. The materials are okay, but I don't recommend it.
