Most Helpful Positive Review Drop in quad rail for the S&W M&P 15 Sport

Most Helpful Negative Review Poor qualuty
The main flaw with this rail is that the top and bottom rail are not designed to be flush together when inatalled. The 4 vertical screws that hold them together, leaves big gaps between the upper and lower rails. They never go together straight. There's always a lopsided mess. The one I used, always...

A.R. 15 fit right in no mods easy

by Kel, Verified Owner from ND, United States Written on August 28, 2025
Weight: 12 oz
Length: 6.7 in this fits the handle that’s in between on the A-frame sight on Ar 15s. It’s about 6 3/4 inches.
Height: 2.5 in
Internal Diameter: 1.7 in
Color: Black & Flat Dark Earth

I hope they continue to make this. This was an excellent product. M4/AR15 Car Length Drop-in Quad Rail. The pamphlet calls it model 4–15 two piece drop in carbine length quad rail system.

We like the AR with the A-frame sight. So this product is perfect for that model the A-frame sight is very accurate and really good. The military uses it too solid performer. When we’re not using the scope, we switched to the A-frame site which is built from the manufacture.

Nothing bad to say about it. It fit right on. We got the extended rail system up top. They do make one without the overhang. We wanted the extra rail up top. I did file it back just a little bit. I didn’t want to touch that would be the top extended rail toward the bolt chamber Other than that it fits 100% perfect fit.

Super glad we got it. Excellent product. If we buy another ar15 , I’ll definitely buy this again.
Pros:
  • Excellent product
Cons:
  • None
  • na
Best Used for:
  • AR15

UTG drop in carbine rail with extension

by Bob, Verified Owner from OH, United States Written on April 10, 2025
Wow, UTG Pro is legit. This drop in handguard is so easy to install and locks up incredibly tight. I built a Mk 18 Mod 0ish carbine, and this rail was 1/4 the price of some other rails. All I wanted to hang on it was a light, forward grip and sling QD, so it does that perfectly. UTG Pro is US made, buy with confidence.
Pros:
  • None
Cons:
  • a little heavy

This Quad will take your AR places.

by Adkborn, Verified Owner from MD, United States Written on March 9, 2025
This is the first accessory I purchased for my Quadless Runner and boy am I happy with it. Quality is spot on, the price is phenomenal and it was very easy to install. I ended up not using the Delta Ring wrench to install it because the wrench forced the ring down at an angle and the rail never seated correctly. When I used my hands to push down the rings, the rail slipped in without a problem. I give it 5 stars!
Pros:
  • GREAT PRICE
  • Ease of install
Cons:
  • None

Good upgrade

by Dusty, Verified Owner from ME, United States Written on February 5, 2025
Bought this for my smith and wesson m&p 15 gen 1. Now I can forward mount accessories as I have much more real estate. Solid lock up, I now have an Operation Iraqi Freedom style Ar 15. Buy this if you want a better rifle than traditional cheap plastic round handguard.
