Fits perfectly

by PhysxNinja, from AZ, United States Written on October 28, 2018
Fit and finish are both very good, and the included hardware has thread-locking compound already applied. These are designed specifically for Anderson free-floating handguards, which have a wider fastener spacing than those from other manufacturers.
Pros:
  • Excellent fit and finish
Cons:
  • None
Best Used for:
  • Anderson handguards
Would recommend: Yes

Heavy for the length

by rambie, Verified Owner from FL, United States Written on June 26, 2017
Looks proprietary to the Anderson Manufacturing upper.
5.63" 3-hole one weighs 50 grams, or 1.8 oz. Feels heavy, especially since it's further from the axis of the rifle.
requires small allen wrench to cinch down.
Otherwise unremarkable and probably the only rail solution for the Anderson ETC upper, unless you want to tap your own holes.
Pros:
  • perfect fit for Anderson Manufacturing
Cons:
  • weight for the length a bit heavy
Best Used for:
  • Anderson ETC uppers
Would recommend: Yes

EXT Rail Review

by Cameron9mann, from NM, United States Written on May 17, 2016
This product was just as advertised. I am please with the product I received. I was looking for a small rail to mount my bipod to my Anderson AR. This rail was easy to install and so far has kept my bipod secure. I would recommend this product to anyone. I on the other hand would not recommend using Optics Planet to my friends. When I initially placed the order I was told everything was in stock and would ship that day. After waiting a few days with no indication of the items being shipped I contacted Optics Planet to find out the scope riser also on my order was not in stock and they were not sure when it would be. I was not notified of this and who knows how long I would have waited if I had not contacted them. Note to anyone who orders through the company stay on top of your order.
Would recommend: Yes
