Not the TRS 26, but I use the TRS 25 Hi-rise, on one of my 16" uppers and it works well for a 1x RDS. It's been dropped once, off the tailgate of my truck and once, someone knocked it over, while sitting in the range gun rack and both times, it held it's "0". Illum. is brite. I have mine mounted on a 45 deg. mount, far fwd on the receiver and I use pos. 5 thru 8, for brightness settings and I can see the dot/target just fine and I'm old and wear glasses. Bushnell makes a great product, that's reasonably priced. I don't think you will have any issues with the TRS 26. Mac
