Most Helpful Positive Review Troy it's a household name
This is very nice hand guard for the price. The machining is high quality. Its extremely lite, it only weighs .620 lbs for a 13" hand guard not including the barrel nut. The inner diameter is 1.37" outer is 1.75" It does not come with a barrel nut and will attach to a standard ar-15 barrel nut. Make sure the barrel nut does not have groves on the outer housing. To be sure just order Troy standard ar-15 barrel nut listed here on Optics Planet. It comes with 3 rail attachments. Make sure you attach the rails before you mount the hand guard to your upper. The only con is having to take off the ha...

This handguard was very easy to install on my 300 blackout build. The material is very sturdy and does not feel cheap. The finish was smooth and clean as all other troy products. Very satisfy with this handguard

13” Troy alpha rail

by T, from PA, United States Written on March 3, 2019
Purchased the 13” Troy alpha rail for my Sig M400. Fit was almost perfect, the alpha rail was a bit higher than the rail on my M400 but that little bit it was off wasn’t a big deal. Overall fit and finish was awesome! I would buy this rail again!

Great, quality, light-weight product, if somewhat lacking for attachments.

by Kentucky User, Verified Owner from KY, United States Written on October 21, 2018
Like most Troy products I've used, this hand guard is well made. It's light, fit and finish are excellent, and I saved about 10 ounces over the Troy Bravo hand-guard it replaced. Installation is fairly straight-forward using a standard AR barrel nut and 3 plates and bolts that tighten around it.

The hand guard texture is a little rough, which should be great for gloves or gripping in the rain. The attachment systems include 3 picatinny rail sections that attach in a manner similar to key-mod, but I think its Troy proprietary. Ultimately I wanted the hand guard to bring down weight, and offer a cleaner look than its replacement. It succeeds well at this, just realize if you want to attach a bunch of gear you will be somewhat limited compared to a keymod or m-lok set. Like any free-float hand guard there is a small amount of play at the very end, but its not more than other quality sets, and for me irons are just for backup purposes.

Optics Planet shipped the product fast, and gave me an excellent price. Highly recommended!
Pros:
  • good quality
  • Lightweight
Cons:
  • attachment options are limited
Best Used for:
  • clean lightweight AR builds

A Rail Built to Last a Lifetime

by Dennis Brown, Verified Owner from VA, United States Written on January 21, 2018
Very easy to install, looks great. Used MBUS sights and was on the target first shot, Troy has some of the best stuff out there. Tough built, but very light, and gave my rifle a balanced feel. Looks great too.

Pros:
  • Comfortable
  • value for $$

Cons:
  • None

Troy Alpha Rail 13" - AR build

by Jorge, Verified Owner from CA, United States Written on November 7, 2016
The rail is surprisingly light. It has a solid feel with great finish. I have not assembled the AR build but am extremely happy with the quality, look and feel. Rail pieces that come with it are great to add equipment just where you need it, if any. I will just have a bipod for my SPR.

Item as described

by Mrome, from OR, United States Written on September 12, 2016
Item was semi simple to install. The Rail attachments not so much. Takes a couple tries, might have been easier to add them before installing on rifle. The rail is very light and a great add to my m4. Overall its a great product and id recommend it.
