yeah i was going to run it on .28 out of the box anyway think .20 are pretty pointless in my opinion. all i am thinking of doing to the gun overall until something breaks is hop rubber, nub and tight bore barrel maybe hop unit further down the line. 100% going to run it out of the box on .28 though first and i might be more than happy with it who knows? also @Rogerborg that does sound like it should be standard practice for new guns but have not seen anyone mention that before defo going to do that to make sure it is clean from shipping. It is going to be waiting for me at home when i get back tonight got UPS tracking up on work computer constantly checking it while the Mrs is even reluctant to answer the door haha.
