Has anyone tried one of these seals from GMAC?

Both the woods-mod and the 0-ring work good:

oh yeah
not gmac seal but simular
i cut a transfer port seal in half.works great
I put a top seal on all of my Crosman pistols - I popped to B&Q and bought a packet of rubber seals for Ã,£1.99 and they work really well. :)
Thanks for the info guys.
I used a Danco #36 O-Ring from Home Depot. The dimensions of the O-Ring were 5/16ââ,¬Â OD x 3/16ââ,¬Â ID x 1/16ââ,¬Â. That was close to the size I needed, but that it was too big to fit in breech. So I put the O-Ring on the transfer port and trimmed it down with a pair of scissors. I finally got the O-Ring to fit in the breech. After putting the airgun back together, the leak was gone. I also gained around 20 fps too.
At about $4 US, I may order up some seals from GMAC too.

i dont know about the o-rings
the transfer port gasket seal has a line through the middle of it cut along that line with a fresh razorblade.you will end up with two equal sized top seals
