They are difficult to run if you are accustomed to an AR. Magazine changes are slow, magazine release is in an odd place. Safety selector is weird and you have to lock the bolt back to change magazines. I did not like the left side charging handle or the long stroke to charge the rifle. I did not care for the way they handled or the sights. The magazines are very inexpensive and the guns are easy to clean and maintain. Difficult to scope and horrible triggers.

Shoot one before you buy.
