View Full Version : Most reliable QD scope mount for ARs?
I'm having some trouble deciding between ADM and other comparable mounts for a 16" patrol gun
Leaning towards adm, bobro, Midwest and probably not looking at spuhr because of price

What optic??

I just recently had to make the same decision. I've used Bobro a few times in the past and have been happy so I was going to go that route, but ended up seeing a few really bad horror stories. Plus, their non extended mount is a lot shorter than I wanted.
I've had an ADM Aimpoint mount in the past but never really cared for it. Midwest seems like it might be a little better since it has more adjustment points, but overall I think you have to give up durability to go QD.
Ultimately, I decided to pick up a Geissele mount since they are 20% off for Memorial Day right now.
What optic??
And what do you mean by reliable? Most secure locking method? Or ability to maintain zero after being removed?

Return to zero and overall durability.
Accupower or accupoint

Accupower or accupointOf the QD mounts Bobro seems to have the best return to zero since they have a much higher clamping force than the others.
Overall durability wise I'd probably go with MI or ADM. The Bobro relies on some pretty flimsy screws that hold on the spring bar that it uses as a lug. I've seen a few instances of these breaking or the spring bar not matching up with the size of the rail causing issues.
That said, I used a Bobro with a 1-6 Accupower for a while with no issues and have a Steiner P4Xi now with no issues. I'll probably end up replacing it with a Geissele at some point though.

The author of this article has the same conclusion regarding RTZ. Unfortunanely, Geissele was not included.

http://www.recoilweb.com/preview-a-guide-to-quick-detach-scope-mounts-57239.htmlI would imagine the Geissele would come out ahead, especially if you are using a tool that can accurately match the torque each time.
That said, most shooters probably wouldn't notice much of a difference in real world usage.

I wish Geissele made a QD
Steve Fisher turned me onto the MI mounts and they are pretty much all I use for QD mounts. I run an Accupower in an MI 1.93 mount and it is rock solid. For non QD, Geissele all the way, but for QD, MI is good to go. They have a superior locking mechanism compared to the ADM mounts and the RTZ has not been an issue for me with either RDS or LPVO’s.
Is MI at the level of bobro?

I am curious, why quick release ?? I don’t get the fascination with QR. when you mount an optic, you want it stable. Through thick and thin, up, down, etc. You do not want any movement in the optic or mount. Guys get attached to QR, and I used to be as well. My line of thinking was, “if my scope goes down or gets broken, I can flip it off, out of the way, and do work with my optics.” Well......here’s the truth: scopes don’t break much anymore. Not the good ones at least, and if your scope becomes so damaged in a firefight that it is no good.....I predict bigger problems than just flipping the scope off with your QR mount. Also.....here’s the answer: 45* offset sights. MagPul Pro, offset at a 45* angle. You don’t even have to remove your scope....you turn the gun and drive on.
I admit, I was all about the QR too. However, as someone who shoots a rifle almost daily, at the very least weekly, as a full time LEO Trainer/Armorer, 3Gun competitor, and a PRS shooter, I’ve just never been in any situation that couldn’t be solved by offset sights.
If you’re reasoning is changing the scope to another rifle, keep a wrench in your bag. Problem solved.

QD mounts have more parts therefore inherently less reliable/strong compare to fixed mounts which ultimately has more contact points to the rail.
Heard that straight from Mr. Spuhr himself.

I agree, to that end...new thread
Which are your favorite NON-QD scope mounts for an AR? (https://www.m4carbine.net/showthread.php?207067-Which-are-your-favorite-NON-QD-scope-mounts-for-an-AR&p=2629400#post2629400)

I'm still not seeing how the Bobro is commanding $250 plus?

Off set sights are not an option on the work rifle. Everytime you take the rifle out of the rack in the air conditioned car in the 90 percent humidity weather the scope gets moisture on it. Can't see a thing for a few minutes. AP pro and VX-R do the same thing. Flip caps don't help. David

Plus, if something happens to your primary optic to the point of it becoming unusable, aren't you going to be unmounting it for repair,replacement anyway necessitating removal from the gun/mount anyway? Then you will obviously be rezeroing.
I too used to concern myself with a reliable scope mount, and being able to find few that offered everything in reality that qd is supposed to offer in theory without emptying my bank account I abandoned the notion that a qd mount was needed for optics.
Dueck Defense or KAC 45degree offset irons are awesome.

I do not own a Bobro, so I cannot comment on it, but it does get very favorable reviews. The MI QD mounts that I own have all been excellent with RTZ in my experience. Steve Fisher has a few videos on YouTube with them in use, as well. Steve is a long time friend and I will always trust his word on things like this.

Why are offset sights a “no go” on the work gun? Unless it is a Sniper Rifle and you’re talking about having to jump out and within moments take a precision shot, offsets would work. The ones I’m referring to do not require you to look through the scope at all. That’s the point. You physically rotate the gun inward and have a set of sights to line up.
Unless you’re saying your department will not let you, in which case, wow.....I would campaign hard to get that changed.
