I've been trying out a new to me product from Bobro Engineering that I got from SWFA during the July 4th sale. SWFA also has their house version branded under the SWFA SS line of products. A one piece scope mount for 30mm scope with a quick release lever and built in 20 MOA compensation. It's made of 6061 aluminum and is flat black anodized to mil-spec. At 7 ounces on my kitchen food scale, it is only 2.1 ounces heavier than a 2 piece medium pic rail max strength mounts from UTG (which really surprised me). My test mules have been the Vulcan .25 and the .22 Cricket Mini Carbine and a Taipan Vetran Shorty .22 for a standard 0 MOA mount (shorty has built in 20 MOA).

The reasons I became interested in this type of scope mount include:
  • Being able to remove the scope and reinstall quickly without tools or loss of zero
  • Being able to share a scope on multi rifles quickly. If you have a scope with good turrets, you can swap the scope to another rifle, make new zero adjustments but do not reset the turrets. When finished, swap scope back to original rifle and set turrets back to zero.
  • Have a favorite short range, close quarters "tree scope" for squirrel hunting like a bug buster? Quick swaps. (They make a 1 inch model)
  • Have a new favorite big bux scope and can't afford to buy multiple $3k scopes? Problem solved.
  • Have an airgun that has a loopy trajectory and you run out of rotations or clicks on your turrets? Get the 20 MOA version.
  • Have a rifle with a short pic rail that puts the scope a little too close for a good eye box? They make a version with a forward (extended) mount.
  • Have a compact scope like a bug buster or AR type scope? They have a "close ring gap" model.
  • Prefer to mount your scope with turrets closer to optical zero?
This mount is well engineered and made in the US by a Veteran owned company.

Good explanatory video @ 8541 tactical YouTube channel.


On my cricket mini Carbine after initial mounting and zero; I removed and reinstalled the mount 7 times. The zero did not budge. Not a single click in any direction. I'm sure this repeatability was also a function of the Athlon Midas 2.5-15x50 scope with its excellent turrets but still - I was pretty impressed.

 
A couple weeks later, I picked up another Bobro mount with no additional built in MOA. It's currently mounted on a Taipan Veteran Shorty which already has 20 MOA built into its updated (from mutant) 1913 pic rail.

New observation.

One small difference I noted in this scenario because the pic rail has the slope vs the mount. If you remove the mount and reinstall it, you need to make sure you select the exact same pic slot it was previously on. Otherwise, your POI will shift by a click or 2 up or down if you miss your original pic slot that the scope was zeroed with. Laterally, it doesn't budge regardless.

Della dog, I'm really digging that BLAC lever device on it. It just swaps instantly to different pic rails with no manual adjustments needed, ever.

Now I'm scratching my head thinking about how to adapt a BLAC lever to an Atlas bipod which uses the American Defense lever. That lever almost always needs a little adjustment to close right when moved to different pic rails.

I suspect that adjustment for the ADM on the different pic rails is due to the slight variation in specs of the rails. Even rails of the same manuf. can vary in their tolerances ever so slightly. You're spot on with the elevation issue between ra
