Most Helpful Positive Review Great Quad Rail System
Replaced the standard AR forend on my Bushmaster 6.8 SPC with this quad rail. Easy to install and well built. I have mounted a streamlight flashlight, UTG green laser and Magpul angled foregrip. Has withstood the recoil of the 6.8 SPC round after approximately 500 rounds without a problem. Also ...

Most Helpful Negative Review Picatinny Rails NOT standard, if you're planning to mount ANYTHING, get something else.
I would LOVE to recommend this product but simply cannot. Product is solid, easy to install, looks great. BUT, the picatinny rails, NOTHING FITS! Lights, and scopes that fit perfectly on other weapons and their rails will NOT fit on these. My understanding was that picatinny was standard, apparently...

The look and feel of this quad rail is top notch. It holds all my accessories and feels better on my gun. I’m glad I bought it. My rifle is more functional and sexier now! lol. Thanks Optics Planet��

UTG Pro AR15 Extended Length Drop-In Quad Rail (M&P15 Sport II)

by JMShelko, Verified Owner from VA, United States Written on March 6, 2025
Fitted this to my S&W M&P15 Sport II and it immediately got rid of the looseness in hand guard from a previously fitted Pro Mag quad rail with aluminum heat shield that itself had replaced the OEM heat shield-less plastic hand guards from S&W. The extra real estate is nice ahead of the A2 front sight. Time will tell how this holds up, but for the price and post-install I feel satisfied.
Pros:
  • Cost & Functionality
Cons:
  • None at this price point
Best Used for:
  • Carbine length AR with fixed front sight post (but definitely fits AR without post.
Would recommend: Yes

Love it on my S&W M&P Sport2

by Dee, Verified Owner from AL, United States Written on February 15, 2025
I’ve seen reviews saying it’s heavy. It feels light to me (just my preference) overall I love it on my rifle. Only wished it pushed out further towards the muzzle more. But, I still love it.
Pros:
  • Lightweight
  • Easy to install
Cons:
  • None
Would recommend: Yes

Fit like a glove...

by traveler1125, from ID, United States Written on September 20, 2024
Was needing an extended rail for my AR Carbine for light and laser. Found this drop-in and it filled my requirement. Got it in and finally got it on the rifle. Excellent fit. Snapped in place literally perfect fit. When I say like a glove that is no exaggeration. Not only changed the look of the rifle, I now have the rail real-estate for any additional hardware I might want. So far very sturdy and should stay in place with the help of a small amt of blue Loctite.

for those of you looking for something like this, I can highly recommend this product.
Pros:
  • Perfect fit Fast delivery. No hassles ordering
Cons:
  • NONE !
Would recommend: Yes
