Blindman from United States, AZ Public Profile

Pros: Fairly light weight
Locking tongues to prevent rotation
Low profile
Doesn't break the bank

Cons: Wrench not included to install barrel nut (you would need a 30mm crows foot to attach to your torque wrench)
Bottom M-Lok slot near gas block will not be usable

All things considered, I'm extremely happy with this purchase. It's within a few oz of some much more expensive ultra lightweight competitors and doesn't skip on usability. It's a lower profile so it hugs nicely and is easy to c-clamp grip if that's your thing. It has anti rotation tabs so once it's set it's not going to move or shift on you. Due to it's slimmer profile, the bottom M-lok section under the gas block will not be usable but that's a very minor complaint unless that precisely where you need a grip to go. If you want a high quality hand guard that's not going to break the bank, this should be a first look item.

I wanted to like this as the stock charging handle doesn't have a very large grab area when running an lpvo, but I couldn't even make myself shoot with it.

This issue is with how the bolt locks forward. With the stock charging handle, it will lock fully forward with even a slow let off. This charging handle I received will not. It seems to start sticking 1/4" to 1/8" from being in battery, and I do not want to risk a round going off without the bolt locked forward. Sadly, I'm out the money for it, but until I can get one in from a different brand, I'm going to have to use the stock charging handle in the interest of safety.

To clarify, it won't do this if you release it from the bolt being locked to the rear as momentum will cause it to lock forward fully, but if it has these issues already a small amount of dirt from shooting could cause issues on the range.

This item functions decently as a foregrip and as a light. I had to change my normal hold pattern to not cover the light, but that was an easy fix. On m-lok, it hold well and doesn't move. I wouldn't try it on a pic rail because it has to mount to a polymer adapter they include, but that just adds a piece to flex. The light has different brightness levels and gets decently bright.

Pros:
Solid mount (on m-lok)
-Light is adjustable, has a strobe function, and comes with a pressure pad if you choose to use it.
-Comes with two rechargeable batteries (usb charging and can be charged in the grip, or removed to charge. They are easily swapped)
-Saves space and weight vs adding a light to the side of the rail.

Cons:
-Light is a flood pattern and will not throw nearly as far as a dedicated light. I would personally like to see a tightened beam pattern even as a flood to take advantage of its output.
-Batteries are of their own design and therefor are proprietary.
-Because it's a flood, the barrel will cast a shadow unless you have a handguard that runs to nearly the end of the barrel.

Conclusion:
I like this a lot for what I purchased it for (smith and wesson m&p 15-22) as it keep weight down, acts as a foregrip, and works fine as a light. I would not elect to throw this on a normal ar simply due to the light pattern and throw range. I have it mounted as far forward as the rail will allow and would not mount it as far back as the picture for the item suggests. This would a
