very interesting link... thanks for posting it... it has been book marked...
I just bought 5 clear Ruger mags, & have a couple of Ram Line high caps, but prefer the 10 rounders... but I do want to replace the mag release, & those guys seem to have a good replacement for the factory bolt release ( which seems not to agree very well with me, on my rifle )... $16.00 for both, seems like a good upgrade to me...
