I thought there was a BIG difference between the blowback and roller locked ones - in terms of recoil/target acquisition. So much so, i've been hesitant to get one without more info. Not like a 9mm has any recoil, I just remember gun Jesus with one at SHOT show a couple of years ago...
Mine is just blowback and it works fine. I do have a PCC buffer in mine, not just a regular H2 or something.

I have a Primary Arms red dot on mine. At 25yds I can shoot the “T box” and hit it again every time the rifle comes back down. I’ve been very consistent with it like that. It may be more harsh than a roller lock but it will do what it’s designed to do consistently.

I have the Extar and really like it. Mounted a small red dot, some flip up sights, and changed the flash hider to one that takes my can. Not any kind of problems with function yet at all.

The company has a strange way of doing business though.

Don't mistake me for saying one is better than the other. I'm sure the blowback ones work great - probably better for reliability than the locked ones in terms of simplicity. Not to poop on the thread, but why other than a range toy? If I want to carry/pack a gun that can shoot rifle rounds, why carry one that shoots wimpy pistol rounds?

Mine is now also my bedside weapon. It’s accurate and I can grab any Glock magazine I have for it. The AR platform is my favorite and my muscle memory is built around that weapon.

My upper and lower are also 9mm specific. Initially I used it as an excuse to assemble something new and slightly different.

I really would like an AR-9 in a pistol configuration that does not require a buffer extension. That would be the ultimate PCC type weapon for me.

Ok - Thanks for the insight. That makes some sense to me. I definitely have never had to rely on an AR style platform. To not poop on the thread - carry on. I'd love to add one to my collection.

Less muzzle blast, cheaper ammo, and you can often get them a bit smaller than a 5.56 or .300

Downsides, you are still shooting pistol caliber rounds, and no matter what barrel length you shoot a pistol caliber through, it won't do rifle things.

PCC's, specifically AR style ones are temperamental beasts. Expect to constantly be chasing improved reliability/durability

Black Friday got best of me, and I ordered all the parts to build an Aero EPC in FDE. 8.3” barrel. I’m going with a Faxon BCG, because I will probably end up equipping the gun with a Law folder in the future.

I will do my best to update the thread after it all shows up.

There are complaints about the aero barrels not having good feed cones, and not feeding JHP well. I guess we will see how it goes. There’s a service called Macon Armory that will reprofile it to fix the issue very reasonably, apparently.

Cheap, quiet suppression. Well, cheap compared to 300BO costs. I’m not really looking for a reloading hobby… yet.
