So recently I decided to do a spring swap in my G&P M4 and royally screwed it up. Parts flying everywhere and all that. While I was re assembling it though I read that if you place your finger on the nozzle and manually push the piston through the cylinder it should eventually become difficult or stop with good compression. When I tried this, nothing like that happened at all. I may be missing something but it looks to me like it has a terrible seal. The O ring seems to be "floating" even though it doesn't look to be damaged at all. Is there something I'm missing? Would anyone have recommendations as to what upgrade parts are required to fix the problem if need be? (Cylinder/cylinder head/piston head)

Additional info- I'm running a 300 mm 6.03 Tight bore barrell

Thanks in advance.
