American Defense makes great products

Second one bough in many years. First one bought over 10 years ago supports a Harris Bipod, interchangeably for my 10/22 and AR15. Second one supporting a Fastfire redot on my Ruger MK2. Excellent choice for increasing accessory utilization across many platforms.
