You pay for the convenience of tool less removal and install at the price of a mount that doesn’t clamp as tight and doesn’t return to zero as well as a properly torqued one. A couple extra minutes to remove 4 screws with a T20 screwdriver to remove and then torque those same 4 screws on install shouldn’t be a big deal.
Bottom line, QD is stupid.
merry christmas everyone!
all QD mounts are not the same. many simple spring loaded cam designs crap and don't stay tight over time, or need to be adjusted.
if the QD mount doesn't hold zero, it is sort of stupid (defeats primary purpose of making it "easy and quick" to remove and put back on)
imho, it depends on the QD maker/brand and specific mount, how well it happens to fit your specific rifle or application, and why you want or need a QD mount in the first place
for example, the Bobro Engineering Scar mounts are unique and patented, self indexing on both axises (pushed forward, and parallel to the rail), and extremely repeatable for zero, even if you move it up or down the rail. there is nowhere to adjust or tighten anything. it is a "spring" loaded press fit, and you can't wiggle it around once it is mated with the rail.
imho, bobro QD mounts are awesome not stupid.
whether or not it is worth the extra money for this convenience goes back to the question of why you want one.
why would somebody cheap like me think spending over $250 for a scope mount is worth it?

i am operator af! i got hot lead flying all around me, and if something takes out my primary optic, i have to be able to ditch the fucker and use backup sights or throw on something else quickly.

my daughter is operator af too, but she's little. even though she's all growed up, she still has to stretch a little to get a good sight picture on dad's wannabe MK20 SSR. we can move the scope back and forth a few slots and not have to adjust fuck all. ready for boom.
it isn't so much that is is "quick" as it is the fact that it holds zero so well. perhaps this says as much about the quality and relationship of the monolithic receiver/rail and barrel as it does the mount.

actually, my first bobro qd mount came in a package deal for the 20S.
the mount that came with the rifle was not ideal. it was an extended cantilever model and the levers were on the left side.
i didn't need any cant but didn't need an extended mount, and i wanted to run the charging handle on the left side.
because of the reciprocating charging handle on the Scar, it is nice to have the mount almost flush with the rail on that side.
long story short, bobro ended up selling me the mount i wanted for 1/2 price, because they could not take back my old mount. great guys and a small american owned and operated business. they also offer LE/MIL discounts.
i got an extra 35mm mount 0moa, left hand levers, extended cantilever, if anyone is short on funds and looking for a cheaper option on an expensive mount. i don't care enough about selling it to list it.
