Has anyone used either the Spuhr R-302 or the R-305 C Thru rail?

Looking for a rail for my SP5 and I would like the iron sights to still be usable with the rail on.

I don't mind having the optic on a low QD mount and the irons only usable when the optic is off the rail. My local shop has the R-302 in stock and that seems like a good candidate, but I also saw the R-305 C Thru, which allows you to use the irons even when the optic is on.

So my questions are:
To anyone who used the R-302, can you still use the irons when the rail is on but the optic is off?

And to anyone who used the R-305, does the optic sit so high up that you get no cheekweld at all? Would it be comparable in feel to something like 1.93 or 2.26 on an AR15?

Thanks ahead of time!

Question about the Infinitech absolute cowitness T2 mount

I am buying an SP5 and would like to mount a red dot to it. The infinitech seems cool with how low it sits and how it allows you to still use the iron sights, but looking at pictures the sight picture looks very busy.

To those who have it: can you still use the red dot with both eyes open and target focus and have that effect of the front a rear irons disappearing with just the red dot floating in space?

Otherwise I'd probably go with a Spuhr picatinny rail + a low mount, which I'm guessing wouldn't give me any type of cowitness at all. Are there any options that would give me a lower third cowitness or is that not possible with the irons on the SP5?

H&K SP5 vs. Sig MPX

Looking to buy a PCC and where I live the barrel isn't allowed to be shorter than 8.9 inches. I'd like something as small as possible, so something with a folding or telescoping stock and a 9 inch barrel. The thing I'll actually be using it for is competitive shooting, but I also want it to be suitable for our SHTF LARPer fantasies.

After some research I narrowed down my choices to a Sig MPX or an HK SP5. The HK would end up being a fair bit more expensive, it's 500 bucks extra to start with, then a stock would be 250 bucks for the telescoping Magpul or 400 for the folding B&T, a rail for the red dot would be 200 and I'm sure it would be even more money to figure out a way to attach a light to it. The Sig comes from the factory with a 16 inch barrel, so I'd have to spend 150 to get it cut and 250 on a new handguard, so at the end of the day the SP5 costs 550-700 more + whatever the cost of mounting a light would be.

The mags for the Sig are also a lot cheaper, you can get Thrill magazines, which I heard good things about, for 70 bucks each here, or originals for 100 while the only SP5 mags available are the original ones which cost 125.

Besides price, the Sig seems more practical, with modern controls and modularity as well as very available spare parts while the SP5 should shoot softer and definitely wins in the vibes department. I'm leaning towards the Sig for the practicality of it, but I can't lie that the heart yearns for the SP5.

Anyone with experience with either or both who can chime in?

EDIT: I also have no interest in suppressing this particular gun, so that's not a concern

Shot a match with an ACOG + T2 piggyback combo and underestimated height over bore

Shot a rifle match this weekend with an ACOG and T2 on top of it, which sits 3.2 inches above the rail, naturally you have to aim pretty high up when targets are close.

On one of the stages there were a lot of close targets with no shoots under them (yes, the target colors were backwards this competition for some reason), I was shooting high on those, but not high enough and it led to SEVEN no shoots right where the targets meet like in the second picture. Some of them were also reduced size and up close, on those I had to hold the dot above the target to not hit the no shoots (third picture).

Lesson learned and now I know to train compensating for HOB at extreme close distances, since I usually don't train with rifles at less than 10-15 meters. I have gotten good at compensating for it at those distances, but not closer, which led to that catastrophe.

Very happy with how the optic setup performed overall, though, everyone else had an LPVO and I didn't feel like I was at a disadvantage.
