The landscape has changed a bit since I last looked at 9mm ARs.... What's your favorite 9mm Glock Mag lower and why?

My intent: Build a suppressed 9mm SBR that uses glock mags, since I have a boatload of glock mags.

As we all know, when you have extra parts lying around, you must turn them into a functioning firearm ASAP. [Coffee]

I looked at building my own and ended up with a Foxtrot Mike FM9 5.5” complete pistol. For the price, I couldn’t build one cheaper myself so I went with that. Runs great with or without a suppressor.

I bought the Spikes, purely because I wanted a spider roll stamp.

My Joe Bob Outfitters 9mm upper n low combo has been a workhorse. Also have a Spikes combo that works swell too.

No experience with a surpressor, but a standard lower with a stern defense mag well ran flawlessly

JBO is very likely a rebranded New Frontier

Just stick with a spikes tactical lower, upper, and bolt.

Most likely, it looks just like it and when I asked the sales person said that they were made by a well respected company. Anyway I built it up with kaw valley parts and have been very happy with it.

I built exactly this on a Quarter Circle 10 lower.

Very high TactiCool factor. :)

Quarter Circle 10 and Foxtrot Mike are the two I'd buy again. Out of about 10 that I have used either for myself or helping friends get one together, they have been the best.

KE, New Frontier, on a few samples, had some small QC issues. Some I could fix, each had a receiver the owner had to send in for repair, and one for replacement from KE. KE was great to work with and made it right, probably a fluke. I do have a Mean Mag (not durable) and Stern (very good, but expensive) insert for standard AR15 lowers too. The nice thing about the Stern is that one could have one SBR stamped lower.

dedicated lower, joebob, frontier, spikes etc, or stern mag adapter. I've had them all, w/out any issues, got bored and sold them. That one SP linked is a deal of the day, buy, you can't go wrong with.

I just use my regular old lower and EndoMag inserts.

Are the Foxtrot Mike lowers usually sold as rifle, pistol or other?

As with any stripped / bare lower, without a stock, Other

I have a Diamondback DB9R that works great with and without a suppressor. I rarely shoot it now due to my Colt SBR 9mm getting out of jail but still take it out on occasion. Only issue is bolt lock back with Magpul mag. It works fine with factory Glock and the one it came with.

Aero 9mm lowers or just Aero Lowers in general?

Aero 9mm dedicated. Saw one at Tanner last weekend. I would just stick with Spikes and have a dedicated bolt, upper and lower from the same manufacturer.

I cerakoted an Aero 9 setup for someone, and while I didn't shoot it, it did look nice and reports are that it functions fine. Don't know anything beyond that

I'm "someone" now!?
I built this for my cousin, the cerakote job was super nice. The Aero buffer and spring are good for a regular mil-spec tube. The buffer tube for this PDW brace was a little short so I had to file the plastic off of the buffer a little bit.
Bolt didn't hold open on the last round but bending the little wire inside the upper receiver solved that.
I personally run a Colt pattern and never had any issues.
