Great look installation could use some updating

by Ace, Verified Owner from MI, United States Written on July 12, 2021
I purchased this 7.5" handguard for a AR pistol build. The 'S' cuts are good looking. The finish is good quality, however this add-on came with zero instructions. Timing the barrel nut with the gas tube wasnt a pain, but there are plenty of other after market products with wrench flats that don't require timing.
Pros:
  • simple install
  • M-Lok compatible
Cons:
  • No wrench notches
Best Used for:
  • Upgrade
Would recommend: Yes

Great product but POOR service from optics planet

by Noah, Verified Owner from MI, United States Written on February 22, 2021
This is an amazing hand guard and looks great on my ar. Only thing is is it had a huge ding in the rail about an inch in. I had planned on returning it but they haven’t even refunded me for a guard I sent back weeks ago. Just be warned that if you get a damaged product it may be weeks. So end of the story. Be ready with a paint pen because there’s a good chance it’s been thrown around their warehouse
Pros:
  • Great looking
Cons:
  • Probably trashed by opticsplanet employees
Best Used for:
  • Good for billet upper AR
Would recommend: Yes

awesome FFHG

by Cyberboy, Verified Owner from CA, United States Written on January 3, 2021
Cons: its heavy and thats about it.
Pros: everything about this is clean. I wasnt sure aboit the s patterns because they are literally useless. Other then allowing heat to escape and also keeping you from plugging every hole with rail guards or cool awesome gear amd attachments. Although i do wish i had more mounting options instead of these s patterns. But with that being said, they look pretty sick. I usually hate things that their sole purpose is looks. But it isnt just looks. It keeps you from blockimg the holes that allow heat to escape. So all in all, a great product.

clean and light

by Cyberboy, Verified Owner from CA, United States Written on December 16, 2020
The item arrived very quickly. It snaps right on to my rifle. It is very very light and a very clean looking hand guard. All of my accessories snap right on to 8. I would buy it again when I get another rifle because I love it so much. Merry Christmas.
