Most Helpful Positive Review im happy with it
Does what I ask, shoots straight with no issues. Only complaint is the finish scratches pretty easily but I really don’t care about that as long it works. I never heard of this brand prior to buying it, but I would definitely use their products again.
Most Helpful Negative Review This isn't about Optics Planet, its about Grid defense/Ghost
I'm writing this to let people know about my experience dealing with Grid defense/Ghost firearms, as I bought this straight from them NOT optic planet.

havent shot it yet, my RRA BCG wont insert forward

by Glenn Strong, Verified Owner from UT, United States Written on January 20, 2025
Haven’t shot it yet, my RRA BCG won’t insert forward without a lot of help. Very stiff. Used a buddies more worn BCG and it was a lot better although somewhat stiff.

Not too bad.

by KLLRTHRTN, Verified Owner from TX, United States Written on February 2, 2024
I really like the upper. The only reason I gave it 3 stars is that it's not truly complete! It does not come with a BCG or a charging handle.

It's great

by Jr, Verified Owner from PA, United States Written on January 13, 2024
It's pretty great for what it cost. Very accurate and feeds and cycles absolutely fine.
Pros:
  • Price
  • accuracy
  • Weight
Cons:
  • Wish it came with a 7 inch handguard instead so I didn't have to swap it out

Great looking upper

by Woe, from OR, United States Written on September 23, 2023
I love the color of this upper, fits my lower with ease. Iron sights and red dot went on with ease. Taking it out to the range to sight it in with subsonic rounds. The upper itself is light weight and feels very well designed, I would recommend this upper.
