According to internet reviews there are shooters claiming that the "ZR mount" is excellent, however there are a large number of reviews claiming the opposite.
Here are a few examples..........
"THE FRONT RING CAME OF THE PINS ON THE FIRST DAY OF USE WHILE ZEROING. THE PINS STOP MOVING FREELY WHEN YOU TIGHTEN THE SCREWS ON THE SCOPE. MY CROSMAN OPTIMUS .22 HAS A DOVETAIL TO WEAVER RAIL. MOUNTED THE BULLSEYE ZR MOUNT ON IT. SCOPE WAS 2.25IN. HIGH. THE SCOPE WOULD NOT ZERO EVEN USING SHIMMING. MOUNTING THE BULLSEYE ON MY RIFLE WAS MISSION IMPOSIBLE."
"The ZR mount has low rings, on some scopes the middle section with the turrets extends a little below the main tube. Enough where it hits the ZR mount. So you can not use that scope or if it just needs a small amount of clearance shimming the bottoms of each ring might raise the scope enough for the center of the scope to clear."
"I bought the BULLSEYE MOUNT and the group of my gun went from 1/2 inch to 2 inch. this thing is too flexible for any accuracy. I sent it back.
If accuracy is an objective DON’T BUY."
Generally i use vortex scopes so I will be testing a few of the ones here before i make my mind up.
"I bought one about 6 months ago and my groups went from dime size to inch and one quarter. Needless to say I sent it back. If you like accuracy don’t even consider this toy!"
" I had it on a Benjamin NP2 in .22 caliber. Was terrible!! Every shot was in a different area on the target, wouldn’t hold a tight group. I removed the sight and put the same scope (as on the mount) back on the gun and all was fine. Don’t know what else to tell you."
There are a lot more but this is enough "negative"
It's a rather pricey mount that limits the "choice of scope" and simply too expensive to just "buy and try"! Please keep us posted concerning how the mount works for you!
