NcStar Mark Iii Tactical Scope Adapter w/ Double Weaver Base 34mm

by HillBilly Bill, Verified Owner from NY, United States Written on March 4, 2017
Unit doesn't fit anything. Inside measurement is off. Hole is not not bored perfectly round or in center. If it did fit on a scope it would be crooked. Sharp edges will maul the finish on your scope. Great concept, too bad it was executed so poorly.
Pros:
  • None
Cons:
  • Fits nothing
Best Used for:
  • paper weight
Would recommend: No

good product

inside measurement is off. Maybe just my piece, but I used a caliper I use on parts for musical instruments I make which has to be exact. Also it not quite a perfect circle slightly elliptical. That makes it even harder to put on. So where you plan on using it is slightly less then 1"-beware
Pros: good product great value
Cons: not quite an inch on the inside-not exactly circular
Would recommend: Yes

Double adapter is not practical

by Legacy Reviewer, from WA, United States Written on July 12, 2010
Should not order if you have a zoom scope (variable magnification), because you can't turn the scope zoom to adjust the magnification because the adapter is in the way, and also you can't read the magnification (zoom) that the scope is set-to because the adapter covers the magnification scale. Recommend you use the single adapter is you have a zoom scope.
Pros: Easy to install
Cons: Doesn't work on 'Zoom' scopes
Would recommend: No
