Most Helpful Positive Review Extended Carbine Handguard
This hand guard is great if you want something strong, looks excellent, and allows the use of a little more space to the front end of the barrel while retaining the fixed front sight post. A free float design without changing everything to have it.
Most Helpful Negative Review No T Mark's At All
High quality but very disappointed the rail has absolutely no T Mark's on it as shown in every picture and in description. Only marking is Painted Centurion Arms logo. I will be calling both Optics Planet and Centurion Arms to get the rail I was charged for

My favorite go-to rail

by Dan, Verified Owner from FL, United States Written on September 11, 2024
I used to rely on Daniel Defense rails but the Centurion has become my go-to rail. I've bought 4 of these in different lengths and they are rock solid.

Spend a little more than Midwest and get a massive boost in quality

Bombproof Old School

by ZomgFaceRoll, Verified Owner from RI, United States Written on July 5, 2024
Centurion makes fantastic rails that leverage the OG barrel nut. Used this on a 16" Daniel Defense barrel with FSB and there's no better bomb proof OG hand guard. Prefer this to the KAC rails.

ar15 carbine

by Vlad, Verified Owner from CA, United States Written on May 30, 2024
Purchased a 9.5 and 11.5 initially. When they arrived, realised my measurements were off and in fsct needed 2x 9.5s. Optics planet provided phenominal customer service and helped me replace the 11.5 with another 9.5 hassle free.

The Rails are worth every penny. Purchased a different cheap rail off a differenr website thinking rails are just a piece of metal at first. Wrong choice as when i went to zero my ar, the handguard was wobbling, had a lot of play to it. Very uncomfortable.
This rail is solid, quality item, exactly what i was looking for.

Rock solid

by Earthling, Verified Owner from AR, United States Written on March 23, 2024
Solid rail real tight fit on upper so no worry on any twisting. Once all screws are torqued down its real solid. Looks real nice as well.

worth the price.

by TX Gunner, Verified Owner from TX, United States Written on August 22, 2023
Well built with quality in mind. The ease of installation and included instructions makes for a great build. It has a great look to the rifle and the ability to mount multiple options, while still keeping a slim appearance.
Pros:
  • Asteticly pleasing
Cons:
  • None
Best Used for:
  • All purpose
Would recommend: Yes

by Sukach, Verified Owner from TX, United States Written on August 19, 2023

Would recommend. Was very easy to install with the milspec barrel nut.

QC Apparently Isn’t a Thing

by Aaron, Verified Owner from IN, United States Written on April 17, 2023
The anodizing is missing on a section of the handguard. They missed a chunk of it. I’d post a photo if I could, and I’ll definitely be emailing Optics Planet and Centurion. I’ve never seen such a pathetic QC miss from a supposedly decent company.
Pros:
  • None
Cons:
  • Poor QC
Would recommend: No

Excellent Quad Rail

by Jesse Gill, from CT, United States Written on January 4, 2022
Took a little fitting to my Noveske upper receiver by my gunsmith, but all worked out! Great craftsmanship, fits all accessories no problem. Solid fit and weight is just right. I would recommend this for anyone that doesn’t want to pay 4-5 bills for a DD quad
Pros:
  • Craftsmanship
Cons:
  • Took some fitting my gunsmith
Best Used for:
  • Any AR Platform
Would recommend: Yes
