Most Helpful Positive Review Great product
I bought this handrail because it was cheap but I'm very impressed with it. Clean and good looking, very easy to install. The barrel nut is steel instead of aluminum like many rails are, and it doesn't require a special barrel tool. Also it came with the barrel extension shims, which most don't. It'...

Most Helpful Negative Review VERY Unhappy Customer. I do not recommend this product.
This is for the GT-16.5-MLK product, but it could be for any of this line. The idea is great, and the product COULD BE. I read the reviews before I purchased and I was aware there is no anti-rotation system on this handguard, but I can live with that. I wanted a long one because I had a 20" barrel ...

Gunter handguard

by Poohbear, from FL, United States Written on July 21, 2021
There is no way to torque the barrel nut without buying there a special wrench. However, they do not tell you that you need that ranch before you buy it. A crowfoot wrench is to wide to fit in their slot. Also, their handguard holes for the screws are way to big and have a to much play. This handguard looks good when viewing online but it is JUNK….

Appears substantial

by Captain Bob, from SC, United States Written on April 3, 2021
Very light. Well made. Will see how it holds up. No way to really lock the handguard to keep from rotating under heavy use with military, SWAT, etc. I used Loctite. For instance, the Yankee Hill system uses screws for antirotation and the gas tube locks the barrel nut.

Awesome rail, less awesome nut.

by Tactical cowboy, from MO, United States Written on February 14, 2021
I was quite impressed with this rail. It is very well machined, super slim, extremely lightweight, and it's at a fair price. It feels great in the hand. I absolutely love how it looks as well. I have only one complaint, and that would be that I was having gas block trouble on my AR, as a result I was putting the handguard on and pulling it off a bunch of times, and the piece that the screws thread into is just aluminum. One of the screws on the bottom stripped out the last time I put it on. Granted, that is partially my fault for running the screws in and out so many times, but it would have been nice if they were threading into steel instead.
Pros:
  • Price
  • Fit and finish
  • Looks
  • Super slim
Cons:
  • Aluminum nut

Guntec Handguard 15 inch

by usmceod, Verified Owner from FL, United States Written on February 14, 2021
Light weight and serves its purpose. Installed on an AR9 w/ 16inch barrel. Had to weld a socket to an adjustable wrench to use for tourque. After I installed it I realized the flash suppressor flats were under the gaurd so I had to remove it again to clock it. Over all very satisfied with the results.

Nicely made

by Vince, Verified Owner from NJ, United States Written on January 24, 2021
At first glance I was a little put off... it appears to be virtually identical to the Chinese ones I used to get a few years ago, for half the price.

But wait! The holes line up!

Seriously, though, the workmanship is quite good, and as a result it is a lot easier to install. Since it isn't a 'pinch type" it is a little harder to index, but in my opinion the smooth bottom near the receiver makes it a bit nicer to hold.

I heard that a proprietary wrench is needed... but I was able to run it down pretty hard with a 32mm open-end wrench. A decent adjustable would work as well. It only goes to 30-80 ft-lbs, which is not a lot of stress on a nut this large.
Pros:
  • Comfortable to hold
  • Fairly easy to index
Cons:
  • None
Would recommend: Yes

Excellent 15" handguard

by Ed, from MI, United States Written on January 20, 2021
Lightest handguard I've come across. Solid construction, great finish, and looks cool! Came with barrel nut & 6 mounting screws. No "proprietary" tools are needed to mount the handguard, & no tools are included. Handguard came in hard, clear-plastic packaging & shipped in a good sized box with plenty of bubble wrap. Unbeatable for the price!
Pros:
  • Outstanding Value, well made with head turning looks,
Cons:
  • None
Would recommend: Yes

Great value

by Tinova, from TX, United States Written on January 15, 2021
Delivery was 3 days.Easy to install. Barrel nut could have been more snug as the screws move it ever so slightly. Tweaked it and it looks great. The price was amazing. The finish is good as any 2x price I’ve seen.
Pros:
  • Finish and price
Cons:
  • None
