As always my order shipped on time and arrived in perfect shape. I knew the product was back ordered when I purchased it, so didn't mind the wait time. But as always OP did one better. My quad rail arrived w a bag full of black rail covers for free, I guess to make up for the delay. Now onto the product, the handguard color matched the rest of my Magpul Fde furniture perfectly and was easy to install. The only problem I ran into was that the last Allen bolt that holds the two pieces of the hand guard together on the top rear can not be used. The gas tube is right in the way of the bolt hole. K...

Good product at an excellent price

by mpasowicz, Verified Owner from CO, United States Written on September 7, 2017
Seems to be of decent quality. Definitely the most cost effective option for a Carbine length quad rail in Flat Dark Earth Finish. Unfortunately, this version does not come with the rubber or polymer rail covers.
Pros:
  • cost
  • Color option
Cons:
  • little heavy
  • No rail covers
Best Used for:
  • Upgrading entry level Carbine Rifle
Would recommend: Yes

Great deal for the price

by The beast, from CA, United States Written on August 26, 2017
For the money, you can't go wrong. It feels sturdy and drops in perfectly. The only con is it's weight. It's heavier than you might think, which when all is said and done is not a bad trade off. I would recommend this part for any budget build where weight isn't a concern.
Pros:
  • Drop In
  • Solid aluminum
  • Clean finish
Cons:
  • Heavy
Best Used for:
  • Budget builds
Would recommend: Yes

by D, from TX, United States Written on July 6, 2017
This handguard was a steal of a deal. Easy to install.The tan finish was good.Fits a lot tighter than the original plastic handguard. Would of given it 5 stars but it didn't come with the plastic rail guards.

As advertised

by Liloldman, from IL, United States Written on March 18, 2017
Installed on ar15 panther arms. Fit perfectly and was easy to install. I would recommend a helper or a tool to install. I was able to get it done with channel lock pliers and a little determination. Looks good and works great.
Very happy.
Pros:
  • Price
Cons:
  • NONE !

M-4 Quad rail

by Jay, from GA, United States Written on January 3, 2017
Although I am no expert on AR acceseries, this product was well worth the price.
The mounting of this system was extremely easy and very simple.
This quad rail enhanced the looks of the AR quite a bit.
The only ding is a very small chip of paint that has come off. I'm pretty sure that the rifle was laid down
Or placed against something to cause this.

Glad that we found this product and sale! Now able to add "toys"
To the AR!
Pros:
  • Price
  • Ease of mounting
Cons:
  • None
Would recommend: Yes

Heavy but sturdy

by WI, from WI, United States Written on December 1, 2015
This is a solidly built quad rail. No issues with snapping it into place, and it's quite secure. I haven't tested it to see how well it retains zero when you take it on and off, but based on how little wiggle there is, anything like a laser or light should be able to be removed and re-mounted without losing zero. It's a bit heavy, but that's to be expected for a less expensive rail like this one.

Nice handgaurd

by Nick, from OH, United States Written on August 11, 2015
I like the look a lot. Showed up fast. My one and only complaint is the weight of it. I expected it to be a little heavy, but it feels heavier than I imagined because the weight is all out on the barrel. I hate to say it but I think I will be looking for a lighter one in the near future.
