The mount seems very robust and I would expect will stand up very well. GG&G has a very good reputation for these mounts and has been making them for some years now. I do have a Wilson Combat blue shok buff in both my mini's (rear only) - might be doing nothing but I think it must reduce the shock to any mounted optics somewhat.
I have not tried really using the Fastfire in any sort of bench target mode (other then to sight it in initially). I bought it for "tactical" accuracy, so I practice shooting with it mainly from standing, and I'm mainly interested in "paper plate" (i.e. center mass) type repeated accuracy. As long as I can keep my shots in a fist sized group at 50yds from a standing position, I'm happy with it. My scoped Ranch rifle is my target mini.
I've read posts of people getting the bolt out with the GG&G rail in place, but I'm not able to (although I did not fuss with it much). It seems to go back on very close to zero though (a tiny bit off, but surprisingly little) - I only loosen the left side screws (the right side came pre-tighter so I've never touched them, just mount/unmount via the left side screws). But then I also do not remove the bolt every cleaning - just seems unnecessary.
GG&G also offers a picatinny rail, which would also mount a FastFire II or III if you wanted, but would leave you more options too. I got my set as a combo deal on sale from them, so went with that mount.
