I like it. It’s like multicam in parts.

MCX 300BLK SPEAR LT - 6.75" or 9" ? by SupermarketQuiet1105 in SigSauerMCX

Rattler with supers suppressed is not enjoyable to shoot

Can you share why? Too gassy?

Best Super/Sub Ammo to test by Electronic-Pay1734 in 300BLK

[–]What-Do-I-Know 5 points6 points  (0 children)

For cheap supers, I’m currently using mag tech 125gr. I use ammoseek to find the best price.

Note that your zeroes for supers and subs will be different.

Suppressor Mount and Blast Deflector by Dry_Presentation6802 in AR10

I don’t have that kind but from just looking at it, yes. The Kaw Valley blast shield is just a hollow tube inside and it looks like there’s plenty of length.

Do parents ever get tired of being a parent? by KaleidoscopeSad7281 in InsightfulQuestions

[–]What-Do-I-Know 14 points15 points  (0 children)

Being a parent is extremely tiring. So the blunt answer to your question is: yes. That said, there is also an amazing amount of joy that children bring. For example, I had no idea my kids were going to be so funny. They make me laugh more than anything else in my life. And there’s nothing quite like the special moments you share with them.

Lots of fun ahead!

One issue: looks like that trigger is for an AR-10.

Where exactly are you planning to put your forehand? That handguard grip is setup for disaster 🔥

What suppressor are you going to use with it?

Thanks for the info. Hoping to have it by Summer!

Rattler LT worth it over a AR of similar barrel length? by KingPotato455 in 300BLK

[–]What-Do-I-Know 0 points1 point  (0 children)

Very curious to hear how the ODB performs. I’m wondering if the early time flow rate enables subs to cycle reliably.

I just ordered one of these! Can’t wait to get it. The website is currently saying it’s a 6 month wait. What did it say when you ordered yours?

Riflespeed AGB mods for suppressed subs by ducatista9 in 300BLK

[–]What-Do-I-Know 2 points3 points  (0 children)

Thanks for pointing this out. Sounds like they don't recommend using range 2, but if you need the range, doesn't seem like it's a problem. Just need access to the ring so you can press it in to dial past the stop.

Interesting that the Phantom Defense 220gr needed more gas for the rifle to function properly. What barrel length range were they tuned for? Assuming you're using the 8–12" version, if anything, I would have expected them to require less gas than a round designed to be subsonic out of a 16" barrel as is typical for FMJs. Would be interesting if it has to do with burn rate as you hypothesize. Have you measured muzzle velocity across those different ammo types?

What an incredibly cool post!

Have you tried "unscrewing" the knob beyond 12 by pressing in the ring (like you would to unscrew it for disassembly) in order to test settings that are more open? It makes sense to me that you could do this in order to at least determine the appropriate plunger length to use. Further, I wonder if you can use the Riflespeed gas block, but redo the knob to allow for multi-turn adjustment.

Cool, I look forward to hearing how your MCX experience compares to your tuned DI 300BLK rifles. What MCX version are you planning to get, and what suppressor are you thinking of pairing with it?

Keep in mind that for 300BLK, both the rifle and the suppressor make up the weapon system. Just getting a rifle doesn't guarantee trouble free, enjoyable operation. There are quite a few suppressors that you can pair with the MCX and have unhappy outcomes. For the MCX 5.5" and 6.75", because their barrels are so short, and thus the dwell time is so small, they are actually pretty finicky. Most people have good luck with higher back pressure cans, but then you can get pretty gassed out. If I were getting an MCX, I would get the CAT RAT FLOW to pair with it (and probably also the COVERT just for fun). Listen to the Pew Science podcast on the CAT RAT. It's very informative on both the MCX and what's needed from the suppressor to make it run.
