Best Build Components for 9 MM AR Carbine Glock Mags with LRBHO that WORKS ?

As the title suggests, I'm looking for opinions/experience on what components have proven RELIABLE in the build of an AR 9mm CARBINE for use with GLOCK mags.

RELIABLE Last Rounds Bolt Hold Open Feature is a MUST.

Also MUST RELIABLY feed JHP as well as Hardball 9mm Luger.

I'm not looking to spend money for the sake of spending money....but cost is secondary to RELIABILITY....this will be a HOME DEFENSE firearm.

All knowledge re: EVERY component and experience with same greatly appreciated.

A knowledgeable gunsmith will be doing the build....I have been tasked with specifying all parts.

Thanks in advance for any and all help.

Try these guys, I know of several people that have built 9mm AR's with their parts and have had no complaints. https://newfrontierarmory.com/

The do have the LRBHO feature and use Glock mags.

New frontier and quarter circle 10 in that pattern

Hey, you took my advise. Welcome. Nice meeting you at Bob's. :)

I used the New Frontier Lower 80% for my AR9 build. I used a 9mm pistol upper with the dust cover and shell deflector. I did not like the look of the NFA upper, so my build runs but no LRBHO. Annoying, but I am dealing with it.

NFA sells their LRBHO parts and can be adapted to a standard AR upper with some drilling and tapping. I may do this as a last resort.

If you want a lower that takes glock mags, and has an integrated LRBHO then try this:

It's an 80% lower, so this may not be a perfect fit. But...with a plunge router and a jig from 5D Tactical you might have a winner.

Good luck on your build :)
