417 Hop recomendations

[Nick G]

Hi all, a friend has asked me to help overhaul his Umarex 417. It looks like the old hop rubber has pretty much given up the ghost and will be replaced while we have it apart, can anyone recommend a good choice ? the gun has a tight bore barrel fitted and is used as a DMR so we are aiming for 400 to 420 fps. Any suggestions greatly appreciated .

Thanks

Nick

Prommy purple, G&G green or the Maple leaf bunch is all I will ever recommend.

Maple leaf 70 degree (blue) "deceptacon" give you range, "autobot" gives accuracy, your choice. Get the little shaped nub too.
