9mm AR vs .300 Blackout

[SINNER]

Not a paintball gun but Oly still make those abortions with the proprietary mags.

Back to some of the original questions though... anyone who has an AR9 or knows of anyone that has an AR9...what kind of 'running issues' have there been on the platform? Are they picky on ammo? Are they over gassed? Are they under gassed? Do you have to tinker with the buffer weight a lot? What's the general consensus on the reliability of an AR9?

At the end of the day I will end up having to SBR something because what I really want isn't available.

The downsides to the MPX are that components and parts are a pain in the ass to get. Everywhere I've looked it seems pretty spotty for availability of parts to customize it. That said given a long enough time and I could have both an AR9 and a Sig MPX. On paper both are attractive but I want to hear about some of the faults of the AR9 platform (in general).

Depends on what you want it for. If defense, a big 300 BLK pro is you are a mag change away from rifle terminal ballistics.

For a range toy where I want to shoot a lot for cheap and at shorter ranges... what are some of the quirks of the AR9 platform? I am asking for people to complain about it :) I've heard they can be finicky but I don't know how so or how much PITA it will be if I go the 9mm route.

As was said earlier it's probably a matter of which one is first....

For the MPX what exactly is hard to get accessory wise?

Maybe I didn't shop around hard enough but let's say I wanted two barrel configurations with two different hand guard lengths.

If you know where I can get the stuff to do that so I can price it all out that would be good.

I didn't spend a month on it but my searches didn't leave me with more details than what I started with.

The MPX is hotter than Hansel right now. I expect parts to be in abundance in the near future, if not already.

I can find an MPX for sale online but once you get the gun, get a stock, pay the stamp etc etc not including any optic you're already over $2000 bucks not including any upgrades that may or may not take place.

I am of course still learning but I would need to part out an 9mm AR and see how much a ground up build would be.

Then again I don't know who I'm kidding right now. I'm broke! LOL Hopefully the financial situation turns around some sooner rather than later. But when it does turn around I want to know what I am in for whatever route I decide to go.

Welcome to guns.

Gun, stamp, optic is 2K? You don't say!

[SINNER]

That's a cheap date right there. Lol

Truth. 2k is amateur hour.

I'm looking for Tommy to build me a G36C for $4500 ish later this year.

I've got baseball cards worth more than that. Damn glad I saved those!

Ahhh baseball cards ... Those were some good teenage years collecting those.

I think the only way you are getting a spare barrel, barrel assembly, handguard, or bolt carrier group components is if you have a warranty claim or buy an entire upper assembly. I have seen lower assemblies for sale, though, which is a move in the right direction, as well as 8" and 16" upper assemblies. The mags seem pretty easy to obtain, finally (of course, a $55 street price helps with that!). It seems Sig is pretty busy keeping up with demand for full weapons right now, especially with election season upon us. I am fairly confident parts availability will come, but I bet it will take a year or two.
