Just took my gs out today to play and it wont shoot over 270. I had just got it back from GI Sportz when I sent it to them to fix this issue. They replaced some orings and the gauge. Still dosen't work. I took my bolt guide out and saw that it had a small chip in the metal behind the first big oring were it screws in. I ordered a new bolt guide and poppet to see if it works. Going out this weekend to see.
