Great quality & Durability

by calvus, from TX, United States Written on September 10, 2018
These rails by Knight's Armament are great. I bought the plastic ones at first but these aluminum ones are the way to go. The plastic ones warped a bit and just don't feel like good quality. The aluminum ones may add a tad more weight but way better for serious use. I would recommend them for mounting foregrips and such and leave the plastic ones for lights & lasers were no pressure is applied. 4 Stars for price
Pros:
  • durable
  • fit & feel
  • machined well
Cons:
  • price
  • size
Best Used for:
  • foregrip
  • rugged use
Would recommend: Yes
