Yep. No more Bobro anything for me.

Recently went to go change scope out with different scope on a Bobro single lever extended mount(30mm). And when I went to loosen the screw cap off the stud sheared off leaving about 1/4" remained sticking up out of the lower part after top half if ring was removed.

Did you guys get yours fixed if so how? Thank you.

Nope. Not paying them to fix their poor QC crap.

I only use a NIST calibrated torque driver. If their studs can snap from being torqued to spec and they won't stand behind their product, I want absolutely nothing to do with them.

Bobro repaired my two that had problems. I sold the repaired units.

Yeah, I bought into the hype hook, line, and sinker.

I was having issues with a certain brand of QD mounts shifting on everything I tried them on, unless I had them adjusted so tight they no longer functioned as QD mounts

And then I read about Bobro and how they have the recoil lug that fills the slot and prevents fore and aft movement, so I bought a mini-ACOG mount and a 30mm Aimpoint mount from them.

All was well, they were smooth on and off and zero retention was dead on as far as I could tell.

Then not long after, maybe 750-1000 rounds, my groups started drifting bad on both rifles. I went through checking everything and I noticed the rear of the mounts was now flush with the upper rail slot that was behind them, when previously there was a slight ledge from the mounts biasing themselves forward in the rail slot.

Popped them off and noticed the recoil lugs on them looked "squished" and threw them back on the rifle by applying forward pressure as I locked them down, I dropped the bolt twice and they clearly moved rearward.

The flaws I've found in their design is their spring loaded clamp is not strong enough to hold the mount in place itself, and their "recoil lugs" seem to have a very short service life.

Sent them in and they were replaced, then I sold the replacements and bought ADM mounts.

They were great, nice clamping power and no movement. I would still use them if I had to, but I eventually grabbed a bunch of Black Friday stuff with G logos on them and they are even better, though not QD.

But G mounts and Warne MSR stuff are all I used now, I don't mind keeping a small 1/2" driver in my range bag or hunting pack.

So, a tight lever on the nameless brand (presumably Larue) is too tight, but having to carry around a 1/2" driver is not?  I'm confused.  

Yes, the Larue levers need to be initially adjusted tight, but I've never had to use a tool to open them.  Return to zero error is below my ability to detect on a sub MOA precision build.   Not particularly a Larue fanboy, as I have a lot of Geissele and ADM stuff, too.  But, I have no issue with Larue mounts.  Superb return to zero and no problem with adjustment tension.

Sorry to hear that Bobro has not fixed their mountbdesign.

Yes, carrying a short 1/2" wrench to undo a mount is much simpler than having to carry whatever size the Texas-spec wrench is to loosen the nut then unlock and pull up on a lever, and yes that is how I had to use them in order to have them not shift.

Same with mine, nice and tight with no movement.  I always roll my eyes when people bitch about mounts leaving marks on rails and recievers.

Well I contacted  Bobro, $50 and that includes return shipping to all together replace the rings with their newest design and inspection of the mount.

I'm fine with that. Oliver there seemed more than willing to help. Be there Wednesday

Out of the 4 Bobro mounts I only had 1 problem with it moving forward and aft. After using a caliper on the rail that was out of spec. The upper was sent back to the MFG and replaced. All of my single level mounts are rock solid mo matter how hard I pull or push on it.

Add my tally to the count of Bobro scope mounts with a broken stud. Removed the scope today and one nut kept spinning on its stud. Here's why:

I haven't contacted Bobro, I believe this mount is over 10 years old; undecided if I should.

Uhh....Is the recoil lug you measured a recessed cut out?

Yup have a drawer full of bobro mounts. Have sent back 2 for broken threaded shafts and now have a 3rd. Just changed out to all Midwest Industries and Warne Mounts. Not sure why Bobro still uses those terrible threaded shafts vs a bolt going threw the ring. Hell atleast upgrade to grade8.

I had 3 bobro mounts at one time. They all broke. Sent them back, got them fixed, and sold them all.


Now have Geissele and Badger Ordnance mounts. No issues with those.

On the bright side, I'm digging those Bondhus wrenches. Never seen a colored set like that.

Wow. I've acquired 7 over the years, they're my favorite, and I've never had the first problem with any of them.

That is odd.

Are you selling the 34mm dual clamp model? I'm needing one now.

I sold it years ago right after they provided a replacement.

I didn't realize this was such an old thread.
