Nick G Posted October 22, 2018 Share Posted October 22, 2018 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 Link to comment Share on other sites More sharing options...
Supporters Prisce Posted October 22, 2018 Supporters Share Posted October 22, 2018 Prommy purple, G&G green or the Maple leaf bunch is all I will ever recommend. Link to comment Share on other sites More sharing options...
Guest Lord Elpus Posted October 22, 2018 Share Posted October 22, 2018 Maple leaf 70 degree (blue) "deceptacon" give you range, "autobot" gives accuracy, your choice. Get the little shaped nub too. Link to comment Share on other sites More sharing options...
