Re: Trying to decide on a suppressor
I think that everyone gets wrapped up about a QD/FA attachment device being only used for superfly fast connections between two or more hosts while you are shooting. The intent of the designs were not to change the cans from one host to another on the fly. The mounts are designed to have a secure way to mount a can (i.e. the can does not come loose during rapid firing), have it index in the same place every time, and not have to worry about protecting threads that can get F'd in a stringent environment. Shit happens and thread protectors get lost (a lot) and threads are sensitive to the elements. If you bang your rifle around and unbeknownst to you, lose the protector, well, then you’re up a creek.
We have a hog problem in Texas. I get out on the 4 wheeler and hunt. I am in rough country and my gear takes a freaking beating. Most of the time I ride w/o a can attached so it won’t get jacked up. If I come into a group of hogs, I will attach the can (time given) and go. It takes all of 2 seconds. For what I do most, FA/QD works for me. I don’t have a rifle set up to quickly take a hot ass can off and put it on another rig. Nothing is that serious as far a time is concerned.
That said, I am building a precision rig and I will have a TBAC can on it. It will not be used for hunting or surviving tough elements.
The big question is, what do you plan on doing the most with your setup? If it precision work, the direct thread on may be your best bet. I will tell you, from my experience (and I am not a gifted distance shooter), I have not seen groups open up, I have seen them tighten. I have not seen huge POI shift; POI shift is there, but it isn't anything that I have been concerned about. Generally I will zero w/o a can. I will put the can on and note POI shift. Since I most always shoot with a can, I adjust for the POI shift. I just like to take note of the shift.
Admittedly, I am not the foremost expert on precision shooting, nor am I on suppressors. I learn a lot from the folks here too. I base my knowledge on my experience. There are more experienced folks on here than I, and I listen to what they have to say.
