OP buy the cheapest $50-60+ tube, literally not even saying our brand, any is fine
Our failure rate is <~1% and on rifle optics even lower. Any pistol optic company making rifle optics is a cakewalk, you're falling for memes.
It's not even a debate since the R5 was made for Sig by Holosun, I can basically guarantee the price diff is not to step on their biggest customers' toes... They discontinued the cheap 403/503 and suddenly have a slightly different design, new mount and cost even more money.
The only thing more reliable than a random no-name tube tier optic is a electronicless prism or a fiber optic ACOG for $1000+ don't waste your money on a basic red dot tube trying to get a bit more "reliability" like seriously don't buy Feyachi and from $50 to $200 you MIGHT get 1% more reliability, MAYBE 2% if you buy a super shit brand and ling ling had a bad week. Besides Holosun doesn't cover accidental damage a bunch of the time and has a 30 BUSINESS day turnaround that's fucking 6 weeks.
Expensive tubes are snake oil if you're not shooting slipper soldiers for Uncle Sam. If you have to have a brand name, just buy a dirt cheap used eBay Vortex basic ass tube, they will warranty that thing lickity split.
