9mm AR discussion

There was a report on another forum of an oversized modular. Modification of the lower's ejector was necessary to get the upper to mate properly (it functioned after that). There was conjecture that process might not work for all lowers, since ejector designs vary somewhat.

FWIW, the build where this was encountered was an NFA lower - so in the worst case, remedial modification would be possible with the lowers you and mustang are using.

I hadn't heard of firing pins breaking until you mentioned it.

I had to move and bend my ejector to get it to fall into place, but I'm thinking that's not what you're referring to.

As an update, I emailed New Frontier, which is what they basically FORCE you to do to get any service, and they still haven't replied. If their replacement firing pin doesn't beat the RRA's I ordered, they're going to get an ear full.

I'm glad my current projects are going to take up my gun budget long enough for more pistol caliber AR products to hit the market. A 9mm carbine build that takes glock mags is definitely in my future.

The want is strong with this one.

Ps: you've already got quite a collection of Stubbys don't you?

Barrels that is for you sick minded people.

As much as I prefer to build my own, the Sig MPX seems like the way to go for a PCC for an AR fanboy.

Glock mags and CMT sounds like a win

Here's another company making an 9mm AR variant. I don't know anything about them so please don't take this as an endorsement. I've just heard the name floating around for a while and found out today that they opened a webstore

OK, still haven't gotten my safety or firing pin, but she's in her final form. Debating on ladder rail covers instead of the KAC covers. Any input?

This is how I plan for my 2016 to go...

Don't forget the $99 50x scope.

That's the conclusion i've drawn as well. As much as i love to tinker with my guns, there's an element of satisfaction in taking a firearm out of it's box, loading the mags, and sending lead downrange without having to play engineer to get everything functioning correctly. But...

I'm very curious to see the upcoming CMT set-up.
