In reference to the question you asked on the other post
"Does the underneath of the mount get in the way when you're shooting?"
The answer is no, i do not even notice it is on...bbut remember i have never actually had a sling attached to it. Even so i doubt it would interfere with my grip. It may stop the stock being fully closed, but i shoot with my stock extended so it is not an issue at all. Brownells have them for £35.80 plus the rather large £8.50 delivery fee
