full metal rack pistol (AOE’d) 
sorbo pad 

hollow Piston o ring  

shimmed 

Heavy duty bushes 

Orga wide bore barrel 
r hopped 

promy purple flat hopped 

and a tru hop concave hard plastic nub that has been filled with sugru and the shaved to create and nice flat nub with a tiny bit of give 

using 11.1 v it Gives a good 75-80m straight shot 

but since Iv fitted the flat hop im

getting 1 full distance shot and then 1 short and then 1 full and so on and so on ,

it’s bizarre , I’m just wondering if anyone else has had this happen and what was the cause ?
