Casey at TacOrd also sells them, I prefer the knurled finish rather than the grooves in the S&J extension
we have 100s of them in stock they also inc our long life spring and famous no jam mag follower & 3 position sling plateThank you sir.

I ended up buying the S & J Hardware one as Casey's at TacOrd is $18 more and it doesn't come with the spring ... that is another $6.50 so $24.50 more for the same thing ... not worth it for the knurling IMO.
I always got a spring
