need help IDing a site

[4nolz2]

I have gone thru 2-3 sets of gobble dots with the adhesive backing-in these briar swamps I always end up breaking them off.SO last year I bought a more expensive site held on by magnets-now it fell apart last weekend patterning my sp-10 and I am missing a piece I think.

I may want to check on warranty but cannot remember the brand name-does anyone recognize this site? DANG this gets expensive but I really like the fiberoptic sites that fit on the vent rib.
