What Mike said, however much better if leather-covered. ...but bloody hard to find as a replacement unit these days!

Also, if you intend shooting the firearm plenty, just "bite the bullet" and install a red Pachmayer Decelerator, the rifle will outlast the pad anyway (and probably several more in its lifetime!) ...with apologies for the Colonial pragmatism!

And if you leather-cover the pad as well, no-one will ever know what is under there!
