sorry? are you using "freak" and "well made" in the same sentance?
If they were well made and well thought out they would have used a left handed thread to screw the front into the back so it was self tightening rather than having to dismantle the barrel to get the back off the gun when it locks.........everyone that has a freak kit has a little implement in their kit bag to unlock the backs, don't you !
Lets be honest, they're not that good !
1 - the backs lock in the gun !
2 - is an insert sitting on two thin o rings the best way to align things?
3 - why does the back o ring always pinch?
4 - Try and clean one quickly out on the field ! yeah right !
