So, with help from the community, I was able to fix my CTAR Tavor and get it together/feeding/running. I loaded up some .28s and tested the FPS on my Acetech BT Chrono. When I first fired it, at first the bb fell out of the end, then as I kept firing, it registered around 80FPS, then 120FPS, then it jumped to 220-290, then bounced between 250 to 330FPS. Now it is firing at a solid 334 FPS. So I'm wondering, is this normal? Did the gun need time to let everything seal up or something? Perhaps I need to lube something I missed?
