I have 5 of their products and am happy with all. Like most units, one has to do a little tweeking to optimize performance. Took me a long time to find this out, but a 0.007 shim between the front and rear portions of my M77/22 bolt turned that one into a nail driver. It had a slight headspace issue and was not consistently seating the cartrideges in the chamber. Brand of ammo also makes a difference in its performance. I was about to sell it off and tried the shim fix at the last minute. It will stay in the safe to end now.
