I'm sure happy how this gun is performing since I opened the ports in it, it's making one heck of a good pellet shooter plus I've still got the option of using the heavier stuff if I choose, all I need to do is turn it up because right now I've only got the power setting at half way point. Right now it get plenty of shots the way it is and is getting in the low to mid 30fpe range. This gun is one of the earlier Sentrys made in late 2016.
