Dye Excel 14" barrel
PE 68/3000 carbon fiber
Remarkable difference between it and the red and green bolts. The first time I chronoed I thought my gun wasn't working then I notice that it was. It is so much quiter and has significantly less recoil. Accuracy is good. I can't say that it is that much better over the stock bolt, though. Where this bolt excels is in performance. It is much lighter and, therefore cycles more rapidly. Much less recoil makes for more ease of operation.. No chops. I installedthe Boss trigger at the same time and the operation seemed so much more efficient. ROF is limited by the lousy 12bps cap on the e-frame, but with this setup it is very easy to obtain max ROF.
