Bobro Engineering B10-300-340 Dual Ring Dual Lever 34mm

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.

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.

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.

I have a Steiner Military 4-16x50mm scope sitting in the Bobro mount. I am very impressed. There is no movement even before I lock down the two clamps. My current case does not have room for my rifle with scope mounted, so I've been having to remove the scope. The mount has maintained zero after putting it back on.This is my second Bobro mount. I have another on an ACOG. Been just as happy with that one.

Excellent American made scope mount. Engineered to be about perfect, should be a full return to zero due to the precision of the mount.

Very awesome mount. Added to my AR-10 with a Trijicon 1-8x28 optic. Zeroed in the rifle, disconnected using the quick detach levers. Put it back on and zero was maintained. Expensive but worth the money.

GREAT, awesome engineering, awesome return to zero after 8 tests mount dismounts!

Extremely well designed scope mount. Would highly recommend it for any precision shooter looking for high quality mount for their scope...
