I visited the range yesterday, with the Tisas DS9 Carry. The plan was to zero the Viridian RFX45.
I spent maybe 40 minutes zeroing the optic – because Viridian’s instructions were backwards. Once I had the optic zeroed, I began to shoot to test out the optic…during the testing (all 10 min of it), the optic screws started backing out. I wasn’t initially aware, and I’d been tweaking the zero, so the optic’s current zero may be out of whack. I’ll address that at the next range visit.
The slide was hot, and because I was giving the gun the beans, I’m thinking the heat loosened the thread locker, and since the screws are so short, there wasn’t much thread locker on the screws.
I ordered more screws maybe 2-3 days ago (I stated that in my last post). They’ll arrive on 3/10. These are the M3-0.5 x 6mm screws. The gun is currently using a pair of M3-0.5 x 3.4 mm that were included with the optic. I’m now doubting that the 6mm screws will be long enough, so I ordered another set from eBay (8mm)…they should be here within 4 days.
I do have some longer screws that I might be able to cut down with a dremel…they’re too long – I tried using them and they bottom out before they start securing the optic.
Other than all that, the optic is great! Some observations:
- The optic’s front glass got dirty quickly, much more quickly than my other optics, but none are as close to the ejection port as that optic/gun combo.
- Brass was pinging off the optic’s frame, on it’s right side. I sort of expected this, as the prior optic I used on this gun (Cyelee CAT) was also catching brass.
- The glass offers a much wider field of view than I’m used to, which is good.
- I’m able to shoot the gun quickly with the optic, while still being accurate (at 10 yards, too).
- As mentioned earlier, the zeroing instructions that Viridian supplied had me moving the damned POI to the edge of the paper target, which was frustrating.
- Would love for this optic to have a two reticle system, as my Holosun ACSS Vulcan does…I may be spoiled by that double reticle system, as I was struggling to find the dot whenevev I was trying to look down the sight.
- Cowitness of the irons look to be a bit less than 1/3rd, but is still more usable than when trying to use the integrated iron on the Holosun 507K with my Ultralight.
- Due to it being a closed emitter optic, it’s super easy to clean off the carbon and fingerprints.
- The Acro footprint is pretty badass. The two screws that hold the adapter in place will loosen well before the one screw that holds the optic onto the adapter.
- One thing I don’t like about this optic is that it’s so big that I’ve to grab it behind the optic when racking, which is a PITA. I do not like racking a gun by grabbing it’s optic and I refuse to do it. Luckily, this is a setup I don’t plan to carry.
Based on my observations, I just might try to pick up an RFX44…it’ll sit better on an RMSc-cut slide than an RFX45 would on an RMSc-cut slide, for sure.
I love the RFX45 because I’m getting a lot of bang for the buck…the optic wasn’t super expensive because I found it for a good price (much lower than MSRP), but I’m getting a lot from it. Because it has all it’s innards up top within the optic, it sits low on the gun, which helps with cowitness.
I may try to visit the range again this coming Wednesday (my work day – I work not far from my range, so it may be easy for me to visit after work). If not, I’m also off on Friday (my birthday is Saturday). I think I’ll try to schedule Wednesday AND Friday.
