## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    A very good scope mount!
  

*by N***B on Reviewed in the United States on May 2, 2018*

Super happy with this mount. I ordered one each for my Trijicon Accupower 1-8x28 and a Burris XTR II 1-8x24 in. Torqued the rings to 12 in/lbs and scopes do not move at all - even on my AR-10. I have not experienced any of the problems reported on this mount. I spoke directly with Bobro and they described in detail how they construct the mount and how the spring bar should be press-fit into the mount base. Both of my mounts were as described and fit tightly in my LWRCI rifles. I would not hesitate to recommend this mount to my shooting buddies.

### ⭐⭐⭐⭐⭐ 







  
  
    Beware!!  Do not use with M1A Springfield
  

*by S***Y on Reviewed in the United States on August 3, 2019*

This is a very well designed and solid quick detach mount for the Trijicon Accupower.  That being said it does not work with the M1A and Springfield Gen 4 Mount.  The center locking lug sits over the receiver where there is no picatinney rail to mount to.  Therefore, the mount slides forward during firing.  Aside from that this is an excellent mount.  I will use it with my AR Platforms.

### ⭐⭐⭐ 







  
  
    They changed their ring design.
  

*by P***R on Reviewed in the United States on October 13, 2018*

First review was 5 stars for the first one i bought. 3 stars for the new one. Same part number very different rings. The one pictured in the listing is the first design. Works great uses nuts. Second on uses allen screws somewhere between 5/32 and 1/8. Nothing thats available with my torque wrench for the 14-20 inlbs needed.The original hold down with nuts is a much better design,Easy to use. My mount put my Trijicon RS27 dead on side to side at 100yds. Had to come up 4inches and it was on. Have not taken it off and on to check zero retention.Its bigger than it looks and more substantial. Not to bad weight wise.
