Most Helpful Positive Review Knights Armament RAS Mk 12 Mod1
What more can one say than Knights Armament, this is a solid piece of hardware with solid lock up that allows the barrel to be free floated hence providing superior accuracy. The only change that would make it a 5 star review would be to add different size rail covers.

Great item, great website.

by Ryan Brace, from PA, United States Written on November 4, 2020
Came super fast with free shipping, in a nice new knights Armament box. Can’t beat it, I purchased for a MK12 or Sam-r build and can’t wait to complete it. Optics planet is amazing as well, with a 15$ coupon from my last order they gave as a gift, plus the optics planet bucks I earned, I paid a seriously low price for this item. It really does pay to purchase from this site.
Pros:
  • It is knights Armament!
Cons:
  • None
Best Used for:
  • A dmr or spr build, MK12 or samr clone
Would recommend: Yes

knights free float rail

by USA, from CA, United States Written on May 13, 2020
First impression: Light weight, has a very nice feel, no sharp edges.
It would be nice if 4 panels and vertical grip were included (only 3 in kit)
Quad rail with marks. This is a free float system and is easy to install, instructions included. This is one of the best free float quad rails I have found.
Pros:
  • Quality
  • Made in USA
  • Look and feel
Cons:
  • Expensive
  • minimal included in kit
Best Used for:
  • Custom Build
Would recommend: Yes

Great product

by B, from MI, United States Written on June 29, 2018
There is definitely a reason U.S. special forces selected this rail. Very light and has a great barrel nut. RAS has two pins that align the handgaurd and barrel nut so when timed correctly, it stays perfectly square. The military selected this rail over the PRI due to the carbon fiber cracking in the middle of an operation.OpticsPlanet fast shipping as always!
Best Used for:
  • combat
