Most Helpful Positive Review Trinity Force Greatness
I originally purchased this handguard because it was on sale at optics planet. I did a search on google and found a few YouTube videos of guys building guns with Trinity Force parts attached. The information in those videos can't compare to how awesome this thing is when you get it. The quality is A...

Most Helpful Negative Review Good rail for the money
This is a good rail, it has the new style barrel nut which is easier to turn, it was a little to shiny for me, so it was easy to just soak it in a stripper and re paint it. The set screw on the bottom....do not over tighten it as it was strip very easily!

I wanted to hope

by Skyraider, from TX, United States Written on July 25, 2021
I think it is important to note that I have many an AR build under my belt.
I purchased the 12in keymod 2 years ago. Everything was going great until I went to hand tighten the provided screws for the provided rails, they stripped. I was able to get them off with the help of some pliers from inside the guard and removed the section of rail. I figured I could buy some after market sets that would suit my needs. I then went to hand tighten screws that attach the rail to the barrel nut...stripped again.
I decided at that point that I could contact their customer service and see about replacing the screws...no reply. I called, they said they would contact me by email when they could make that happen...no reply. So rather than take my upper into a gunsmith to have the stripped screws removed in an effort to salvage situation, I finally caved and drilled them out. I now have a very expensive paperweight as there is no coming back from this. Crazy how a company could have made a life long customer by simply sending me some screws that I am sure would have cost them a whole $1.
Pros:
  • None
Cons:
  • Breaks easy
Best Used for:
  • paper weight
Would recommend: No

Missing Parts (TWICE)

by Allibaker, from OH, United States Written on January 2, 2020
This product came once without a barrel nut. I went through a lengthy, complicated exchange with OP. I finally received the replacement, and the barrel nut is missing again. I do NOT recommend this item. Order something that is guaranteed to come with all essential parts. OP doesn’t offer answers to why the product isn’t correctly fulfilled; you’ll have to speak to Trinity Force.
Pros:
  • None
Cons:
  • No Barrel Nut
Would recommend: No

Great bang for the buck

by Todd, from VA, United States Written on December 2, 2019
Don't let the low price scare you... it's built from the same aluminum as the other top brands you will find for free float handguards.

Works as intended, doesn't come loose, if installed properly it shouldn't have any play or wiggle in it.

TF also packs in a nice limited lifetime warranty, be sure to read up on that too.
Pros:
  • Durability
  • Material and workmanship appear to be good.
  • Price and warranty
Cons:
  • None

Nice tight lockup

by Jerry Lachenbruch, from OR, United States Written on April 24, 2018
This foreend locks up nice and tight to the upper receiver once the barrel nut is tightly mounted. It came with a couple barrel shims. I used one of the barrel shims. I will certainly be buying it again for my next build. The aluminum material is light yet strong. I like the 15” version for my 18” barrel for added sight radius to help ensure added accuracy.

Looks and Feels Amazing

by Dan, Verified Owner from FL, United States Written on March 13, 2018
This rail looks amazing. The handguard is very sleak and the metal is pretty light. The 15in fit my AR perfectly and for the price range you cant go wrong. I would highly recommend it for anyone looking for a mid price rail.

Solid handguard

by Studly Stew, from MN, United States Written on February 14, 2018
I bought this to replace a cheap glacier guard. It is miles better. After about a month of research and reading many reviews, this was the best I could find at this price point. Easy install, solid performance, looks good. Finding a 1.25" crows foot for barrel nut install was a little tough. Good quality for the price.
Pros:
  • solid construction
Cons:
  • None
Best Used for:
  • Hunting, target, home defense

Bought twice

by DeputyBane, Verified Owner from AL, United States Written on January 17, 2018
So I ah e bought this particular rail twice. Once in the 15 inch and again in the 16.5 inch. Both once installed it lightened the rifle signicantly. I bought the 16.5 to go with my kak industry micro flash can. Which was the only reason for the change. I would recommend this rail for anyone on a budget or not. It’s a great quality rail. Everything you need to install is included if you already have the correct gas tube and block.

Great Product

by chipmunk, Verified Owner from VA, United States Written on January 12, 2018
Awesome product, I got the 15inch version, I wish the tool to tighten the barrel nut on the barrel was included like UTG but I had a few things around the house I was able to use. Once on the gun this thing looks great! Will purchase again!
