I have the same EL, also bought used, and I had to order new slide adjusters before I could get it to work. Once I got everything put together it shoots as good as yours.
I ended up getting two new sliding lugs too. The tape trick worked but didn't seem permanent. I filed them little by little until I got back where I wanted.
Here is a 5 shot group with me removing the insert between each shot.
Even at 50m it still isn't bad. I was using Remington "yellow jackets". I held on the X for the last shot.
I think it will do...
Thanks to all for the advice and direction. I am really happy with this little addition to an already versatile firearm. I have done a whole range of testing with it, but it probably calls for a whole new thread.
