Northman Posted January 2, 2018 Share Posted January 2, 2018 Hi Guys, I'm returning to the sport and have been in the process of servicing and upgrading my old Type 96 sniper rifle from a blunderbuss to something with a little accuracy. The first step was to service the gun and install at PDI Hop-Up unit which is now done but the problem is one minute it will shoot 350-370 fps and the next it will be around 440fps, which means I can't use it. I'm learning as I go on the tech front but everything seems to be working fine - Am I missing something obvious? Please note I have not tested the rifle in the open yet - just chrono'd in the garage - (so could be the hop up?) The rifle is old and still has the spring from when I stopped playing 5-6 years ago. All help is greatly appreciated! Link to comment Share on other sites More sharing options...
Immortal Posted January 2, 2018 Share Posted January 2, 2018 If I take a gun out of storage then first thing I do is: Check/lubricate or replace the seals (or anything deemed perishable...) Hardened, deformed or dry o-rings can give odd results. Link to comment Share on other sites More sharing options...
