I have owned 2 Tac-Sol X-Rings rifles. I SOLD both because of all the problems I was having with FTF, FTE. I even sent one back and they said it was good to go, but when I took it out it still had all the same problems!
And don't get me started with accuracy, when taking into consideration the price you pay. I have Factory barreled carbines that I have done a little work to, that shot better than both my X-Rings rifles! Those rifles for the money are not worth it. Spend a little more or about the same and get a KIDD built rifle!
