Hey Guys,
Had some spare time, so I decided to work on my .22 cal. HP QB79/AR2079-A conversion.
It's had Tank Block/Transfer Port leaking problems since I can't remember .... likely 2018/2019. I think I'd gotten very tired of fixing air leaks ...........
She, her brother and second cousin haven't been shot shot for years. I think I still have parts for 4 QB's/AR's ..... valves, barrels and stocks etc. from 2014/2015.
Fixed the Tank Block leak, but when firing - she's still wasting air out the transfer port/action connection. I believe I set the HP air tank is set around 1300/1400 psi, currently getting around 880 fps with H&N 5.55. Tried Meisterkugeln's, but they were not very accurate.
Looking forward to shooter her again and may resurrect the relatives too
