New style HW piston seal.

[nced]

I thought I'd share this with my GTA triends!

I'm currently working on a HW97 and upon disassembly I've discovered that HW has even redesigned their piston seals. I actually believe that the design change is an improvement and I was very surprised when I chrony readings for CPLs was 900-910fps with the new FACTORY piston seal.  I've been oring sealing my HW springers for YEARS I have a few HW piston seals from my mods over the years so I compared them with the new seal.

I used to shoot my "outta tha box" R9 for a while before oring sealing, but the last R9 I bought was oring sealed without even shooting a pellet over my chrony and that seal is in the middle!

Here is a pic showing a progression of HW piston seals.......

Anywhoo....it does SEEM that HW is revising the design of their offerings and these changes don't seem to be ONLY "cost reducing" changes!
