A while ago there was a post that askes if anyone was interrested in "slicked up triggerguards", the post was on the old forum, long gone. But the guy from Sporter Express made a few posts about it, I think he got one. You might try emailing him if that's the post you were thinking of.

Z1r,
I'm interrested in more info on those release buttons, I've tried the FN style, but the button is too small. Can't work it with gloves on.
