I have me a beautiful Promaster and she just recently started spewing air uncontrollably out of the barrel at an alarming rate....i'm assuming its an o ring. idk but i really would love to upgrade her to the best of my abilities. i need to know what she should get first and foremost and then on from there. she already has herself a feedneck....(got that no more than 3.6 seconds after purchasing the gun) and she has Empire grips. If you could PLEASE PLEASE give me the best option as far as HPR and LPRs go. I'm debating on getting an ASA because i am interested in buying a new gun but i wanna take car of my PM girl first. please hook a ninja up with some helpful DESCRIPTIVEadvice.
THANKS!!!
