I have the TacStar and hate it. The thing constantly comes loose.
I clean my shotgun every time I shoot it; not the entire interior of the reciever, but I do remove the barrel, forend and bolt. Even after a match with only two short shotgun stages, the sidesaddle will loosen; and yes, all the bolts are loctited.
Blue loctite is not going to be any problem to remove. Red probably wouldn't be either, given the small amount of female threads.
The TacStar has no resilient dampening effect, and the females in the backing plate are aluminum. The Vang Comp DSAC is the only design I've seen that appears to solve these two problems.
I don't consider the TacStar to be a serious piece of gear, but it's been good enough for me to learn on thus far. Just be sure you check ALL the bolts frequently - as in, at lunch if you are doing an all-day class or other activity with lots of shooting.
