Most Helpful Positive Review extended rail with cutout for A sight.
I looked all over for a rail system like this.. Prices ranged upwards of $80. I didn't want to pay that amount but saw this one at optic planet for $54.99. So I plunged. I have a SW mp15 sport. The original fore grip was awful. I replaced it with a magpul which again I didn't like.. it didn...

Best for rifles with a fixed front sight.

by Wanna be mechanic, from AR, United States Written on November 10, 2024
Very easy to install and looks pretty sweet on my rifle. I will say though if your rifle has a fixed gas block without the front sight it does look a little odd with a large gap in between the gas block and the cutout of the rail. It’s sturdy though and it holds my attachments very well.
Pros:
  • Easy to install
  • Looks great
  • Very stable
Cons:
  • Had a large gap in between the rail and gas block on rifles without fixed front sight

Fits perfectly on my M&P Sport 2. Replaced the terrible original with a Magpul one, which was okay, but this system takes it to a new level!

Great product

by Homer Carter, Verified Owner from PA, United States Written on February 5, 2019
I wished I could have used this KEYMOD Rail System (Hand Guard), however I was looking for a “Split System.” My AR-5.56 By Ruger has the Front Sight Post which I did not want to remove to install the Hand Guard.
