One thing I just noticed about the Tactical Solutions, is that the colored pipe is set or fixed, where as the HiViz, gives you the option of pipe colors and sizes. These pipes or inserts are subject to breakage and on the Tactical Solutions, I'd have to buy a complete new one. Where as on the HiViz I just pick out another pipe. The pipes can also be bought separately, in a plastic tube, with it's key. ...
Your money, your call and looks like you have some great options. ....
Be Safe !!!
