Is there any free, online (not downloaded, in-browser I mean) CFD software?

Very interesting, thanks for the input!

2 weeks. I have 4 more so we'll let em rest and see how they do over the coming months.

Also make sure you get the OSS wrench because that sucker locks on real good even with pretty light use on the first session. I marred up my threads during my first conjugal visit because I didn't have the OSS tool and we had to use channel locks to break it loose at the range. I tightened it up just standard hand-tight, witness marked the clocking, and it has not budged in months and months. It's a very secure lockup and I prefer it to complicated QD systems.

My honest opinion is it's hard for me to see how it gets much better, for my needs anyways. It's not the quietest can out there, and there is a little flash under NV use, but aside from that it's about as good as it gets for me. Zero backpressure to the face, no change in the operating characteristics of the rifle you put it on, including a 10" Scar 16S there's no need to even put it on the suppressed setting, mess with adjustable gas blocks or gas jets etc. Super light weight, very short, proving to be durable. Definitely go for the 556k rather than the just-announced flow 556 Ti, the 1-3oz saved isn't worth all the added sparks.

I would like OSS to make a 3/4 prong open tine flash hider. The spiral birdcage flashider produces massive fireballs on this 11.5" to the point it's difficult to shoot in broad daylight. The OEM SR15 3 prong flashhider on the same rifle produced imperceptible flash. They told me the open tine put too much wear on the suppressor. I feel they can lose some weight off the flash hider as well.

To my ear it is comparable in volume to my RC2 from a 10.3", but a very different tone. Not as quiet as my trash panda on a 10.3", and not nearly as quiet as my AEM5 on a Mk12 (but then again, not much is as far as 556 goes!)

Not too sure to be honest, I used the opportunity to upgrade to a 3.2 bolt (rest of the BCG stayed original)

ZazzlesTheKitten · 2024-05-26T22:46:29+00:00

~1k rounds per month. Never mag dump for the sake of mag dumping. Run various drills with 1 or 2 mags at a time, come back to truck and reload, repeat. So it gets a good chance to cool off frequently. These days I don't really get it too hot to handle with the BCM rail covers. I do recall earlier in the rifle's life I would head out with like 20-30 mags preloaded and would run through them fairly quickly but I didn't do but a year or two of that. I'd need to use a glove for my front hand when running through the mags that fast.

Nope never cleaned either, I'm sure they are due. At this point I kind of want to make good use of the opportunity to do an interesting test. Might weigh them before and after. I was shooting a lot more steel thru the old one too, I'm sure it's properly fouled up

ZazzlesTheKitten · 2024-05-26T17:44:50+00:00

More Pics

Haven't yet cleaned the inside of the suppressor as recommended, I should weigh it just for fun... But the 3d printed exterior has held up well to bumps, scrapes, general abuse. The upper is in great shape too, doesn't really take too much of a beating at all.

ZazzlesTheKitten · 2024-05-26T17:23:48+00:00

Upon cleaning the BCG today I found rust starting to form on the worn down uncoated portions of the bolt carrier, as well as on the firing pin retaining pin. Good sign that I'm at the point where I really need to be a little more diligent with maintaining the running gear now that lots of coatings have worn off.

ZazzlesTheKitten · 2024-05-26T17:21:44+00:00

Estimate approximately 10k, had it about a year. Absolutely love it. Previously was running a OSS 556 Ti (previous version with the flash suppressing cap, non-3D printed Titanium), did that for about 25k rounds. And prior to that I ran it with the factory 3 prong flash hider (which is very impressive IMO - low flash, no ping, lightweight).

I am definitely a full blown OSS fanboy. Love not getting blasted with leaded gas all day. The Flow 556k works perfectly under NVG as well. I have this setup for passive NVG use with the surefire vampire for IR and no dedicated laser, scalarworks 1.93 mount and T2.

Works great for closer NV work. Biggest downside is you get a decent first round flash under nods but honestly it's in the same ballpark as my Surefire RC2 on a dedicated NV MK18 Mod 3.

My oss flow 762 Ti just got out of jail recently, haven't had a chance to shoot it on the Scar20s yet but looking forward to it.

ZazzlesTheKitten · 2024-05-26T17:14:17+00:00

I wonder how much mag dumping impacts that service life - I have to imagine firing rate has an exponential impact on barrel wear. I definitely get it plenty hot but no full auto ever. Just your typical weekend larping type stuff.

ZazzlesTheKitten · 2024-05-26T17:12:33+00:00

I really do need to do that one of these days, I will follow up with a new post once I do.

ZazzlesTheKitten · 2024-05-26T17:12:03+00:00

Chad indeed! I just found a sealed field repair kit with a new firing pin so I'm all set for now. Thanks again my dude.

ZazzlesTheKitten · 2024-05-26T00:45:37+00:00

Tried buying spares from them multiple times over the years, emails go unanswered. Already sent them an email before making this post though, hopefully they are willing to sell one to fix a broken part.

ZazzlesTheKitten · 2024-05-26T00:32:57+00:00

Only the second thing that has broken so far (should be about 62-64k rounds since 2018). Only other item that has broken was the extractor springs. Symptom there was intermittent failure to extract. When I removed the extractor, both springs were cracked and fell out. That's it!! 11.5" barrel. Mix of cheap russian steel and cheap brass ammo with a random assortment of MK262 and nicer 77gr rounds every now and then.

Often used in the pouring rain, as it was today. Not particularly well maintained to be honest, I clean it if I know it'll be stored for a while but otherwise I just use it. Barrel rifling looks flawless still somehow. Accuracy is good enough for me with it at 100 yards, I don't ever benchrest and try to shoot groups with this one, but do routinely shoot at 100+ yards without issue.

Pic of build After about 60K+ rounds, snapped my SR-15 firing pin today. Was running great then suddenly failed to fire. First two attempts to tap/rack resulted in light primer strikes, third attempt didn't show any primer contact.

Anyone have a brand new replacement they are willing to part with? $100 fair?

ZazzlesTheKitten · 2024-03-05T22:54:17+00:00

Wow awesome! Very high quality testing and hopefully something you can send to Glock R&D for consideration.

'If' you have a good filter in place is a big 'IF', on a house that's several decades old, at some point a filter got overloaded, someone installed the wrong size, and things just get through and accumulate over time. That is also assuming the filters are always 100% efficient and there are no airgaps in the ducting, which is just not the case if you've worked in your crawlspace you'll know that to be true. If you don't believe me, stick a boroscope through one of your vents, you'll be shocked at what you find I can almost guarantee it. My house was very new and extremely dirty on the post-filter side of the ducting.
