Most Helpful Positive Review awesome rail
This is a great rail. It is light, locked up super tight, and is backed by troy's well respected name. The only problem I could think of was when I tried to put magul rail panel covers on, the 360 swivel mounts don't really work well. You have to do some serious wiggling and fitting. (but it can be done) Good product opticsplanet! Pros: lock up Cons: 360 swivel mounts

Would recommend: No

Works amazing

by Steven Wilcoxson, Verified Owner from AE, United States Written on August 25, 2025
This thing is heavy duty and I know it could take a beating. Super happy it had the cuts for knights armament rail guards as well. Definitely recommend if you want something close to a knights armament drop in rail.

Pricing & Realiability

by Phillip Ferris, Verified Owner from AL, United States Written on January 21, 2025
Compared to Daniel Defense this is a lot cheaper. Rails do the same thing and are usually made of the same materials and this is on par with my Daniel defense pic hand-guard yet surprisingly lives up to the name brand item but not for the name brand cost.
Pros:
  • Cheap
Cons:
  • None
Best Used for:
  • AR-15
Would recommend: Yes

Good fit, great quality

by Do the Math, Verified Owner from CO, United States Written on December 22, 2024
Bought this Troy quad rail for a LMT SPM rifle as Knights quad rail wouldn’t work. The Troy quad rail fits well, installation was easy if you have the right tools. Still a little play even after repeated tightening. Would recommend a little LocTite on screw threads if planning for hard, rough use in field.
Pros:
  • Easy to install
  • Great structural quality
Cons:
  • None
Best Used for:
  • AR Carbine
Would recommend: Yes

Troy Modular Carbine Handguard

by JFKSWC, Verified Owner from NC, United States Written on November 1, 2024
Item is perfect and far above it's price point. The reason the US Government assigned it a NSN is clear.

HEAVY DUTY!!

by Hilesfiles, Verified Owner from OH, United States Written on April 30, 2024
I am super happy with this rail. I put it on a RRA M4 that needed more pic rail space and the traditional handguards needed updating. What a heavy duty rail, it's very solid. It dropped right in without a hitch, literally 5 minutes. Popped on my Surefire and voila!

Troy M4 rail

by Andrew Paul, Verified Owner from KS, United States Written on December 27, 2022
This thing is a beauty and was easy to install. A forend removal tool made it even easier. It's a nice, tight fit and has a beautiful anodized finish. I also got a Troy CQB foregrip, a great combination. Didn't add a lot of weight to my M4 versus the stock handguard that came with it. I looked at Knights Armament but heard these were just as good. I can't attest to the Knights, but this Troy is awesome. Very highly recommended!
Pros:
  • Easy to install, looks great, lightweight
Cons:
  • none that i can see
Best Used for:
  • AR Carbine
Would recommend: Yes
