Most Helpful Positive Review A good sturdy forend but could use some improvements
I was looking for a 7 inch handguard that wouldn't break the bank on my pistol project when I found the Guntec Ultra Thin Key Mod Handguard. I was a little hesitant to buy it because it comes with an aluminum barrel nut but then I was also trying to keep the weight down. There is an option for a ste...

Most Helpful Negative Review Well Made Product, but will need Tweeking During Install
This handguard is ultra-light as advertised, because it is thin. I used it to assemble an AR pistol. It will not be subjected to the stress as it would have had I used it on a carbine. However, I see no reason that this handguard will not perform as designed. How strong it will be is subjective....

Great rail for the price!

by Me, from FL, United States Written on July 11, 2019
The rail fit perfectly on my 7 inch barrel build. I would give it 5 stars because it is of good quality and is very lightweight. However it took over 3 weeks to receive it. Optics planet puts this on their website but didn’t have it on hand. It showed it was in stock and then I received an email saying it would take some time to get it to me. This isn’t the first time this has happened with optics planet. It is a great rail. Just be prepared to wait for it if you decide to purchase it.
Pros:
  • lightweight and affordable
Cons:
  • Takes a long time to receive. Probably not in stock
Best Used for:
  • 7 inch or above barrel lengths
Would recommend: Yes

It worked Prefect

by Cb, Verified Owner from WI, United States Written on September 21, 2018
It worked perfectly for my 458 socom pistol. The only thing I wish it came with was a rail to mount a light or a grip other then that it's great. it fit the barrel length so only the muzzle break stuck out past the end as I wanted it to do.

Good for my build

by Pete, Verified Owner from TX, United States Written on July 15, 2018
So far it has been a quality economical rail for my AR9 build. With a blowback build, there was no gasblock alignment to worry about so no need for the included shim and go easy on the torque but the included nut seemed of good quality. The rail itself mounted easily with my only small gripe being that the rail was slightly different then the one on my Anderson upper. Do recommend using Loctite or appropriate locking washer when installing the rail.
Pros:
  • Quality
  • ecomonical
  • ease in installation
Cons:
  • rail
Best Used for:
  • Training and fun
Would recommend: Yes

Looks great however some issues

by Gary H, Verified Owner from OH, United States Written on May 17, 2018
Bought for a new pistol build. The price was good and the length was what I needed. So, I made the jump. When i received the item it appeared solid. Install was a pain. No tools or instructions came with the handguard. The barrel nut will not torque with a regular armour wrench. I had to use a adjustable wrench and when trying to get atleast 40 ft lbs in the holes would not line up. With and without shims. So, I stripped the he'll out if the outside surface if the barrel nut. I've built about 20 rifles in over a year and never struggled like it did with this one. By no means any fault of optics planet. If this product was 30 dollars less I would expect difficulty. Hope this helps if your in the market for a Gun tec handguard.
Pros:
  • Great fde color
Cons:
  • Hard to install odd barrel nut
Would recommend: Yes

ok not the best

by AK, from ND, United States Written on March 2, 2018
Not too bad for the money but no way to torque the barrel nut with the way it is made unless you make a special crows foot or grind one down. company says to use a cresent wrench which I do not like. My Low profile Adjustable clamp on gas block does not fit with out grinding the ribs down inside the handguard.
Pros:
  • Price
Cons:
  • Instalation
Would recommend: No

Lightweight quality @ affordable

by Blockader, Verified Owner from GA, United States Written on January 21, 2018
Purchased this for a dedicated .22lr build to be my daughter's training rifle. It is compact and very light but seems plenty strong. Barrel nut was not milspec wrench compatible, so keep that in mind, I used a regular crescent wrench on the flats.
Best Used for:
  • Lightweight builds.

Thin IS IN

by GUNNUTT, Verified Owner from OH, United States Written on November 4, 2017
These make for a very streamlined look and feel. They install easily and are ascetically pleasing the included barrel nut is able to be done with common tools crescent wrench finish is even and durable. I would definitely recommend this product. They include barrel shims to be added so orientation of nut is correct for alignment of screw holes so that the top rail aligns with the receiver. I use a long base to hold this alignment while tightening the screws that attach the handguard to the barrel nut. The final assembly is solid and very nice handling.
Pros:
  • Price
  • Easy to install
  • performance
  • Great product
Cons:
  • None
Best Used for:
  • hunting
  • target
  • Tactical
  • home defeanse
Would recommend: Yes

Great product

by Matt, from SC, United States Written on November 1, 2017
Bought this rail for my AR build and I couldn't be happier. Fits nicely with my upper and matches my other FDE pieces as well. Took a little while to get to me so don't be in a hurry and expect this in a week. Overall would recommend this product to anyone wanting a cheap price but a bit so cheap product. Very happy
Pros:
  • Lightweight
  • Good Quality and Fit
Cons:
  • Shipping
Would recommend: Yes

Definitely Not Great

by Hrebs, Verified Owner from LA, United States Written on October 5, 2017
It's nothing special. It's not horrible, but I guess it could work for a budget build or a range gun. The "FDE" color is a little off if you are nitpicky about that sort of stuff. I don't really care.
Pros:
  • it works
Cons:
  • Somewhat flimsy
Best Used for:
  • Range
  • budget build
Would recommend: Yes
