||Love this thing. Some of the barrel extensions that have both CW and CCW ends usually have faulty threads but this one is very sturdy and holds together nicely. Can take the abuse of crawling through dirt and brush.
Goes on easily
Hides longer barrel
Has a narrow inner diameter so I could not fill it with foam to make it a little quieter.
(However it still works great.)
