Does this have last rd bolt hold open ?
Michael R on May 2, 2018
BEST ANSWER: The last round bolt hold open option is entirely based on the lower and or mag block that you use and type of magazine.
what else will I need to make this function properly on a 223/556 lower?
robert g on May 3, 2018
BEST ANSWER: You'll need to install a Glock magazine well adapter and an ejector. The placement of these is going to need to be accurate otherwise you'll end up with a lot of malfunctions. There are kits available to help. You'll also want to change the buffer and buffer spring to one that works with 9mm, it's not absolutely necessary but it helps with reliability. It'll be a slightly lighter spring and heavier buffer. Your lower will no longer work with other calibers unless the magazine is compatible with the adapter you installed, or you remove the mag adapter and ejector.

Honestly you might be better off just buying a dedicated 9mm lower. After all the work you'd need to do with your standard AR lower, the price won't be much different and you'll lose compatibility with your other upper.

Hope that helps. Happy building!
Is the flash hider permanently attached or can it just be unscrewed?
E W on May 21, 2018
BEST ANSWER: It can be removed. I think it's 1/2x36 thread.
Is a Spikes 9mm BCG compatible with this upper and a spike lower?
Susan P on May 17, 2018
BEST ANSWER: I put it on a JBO Spartan lower (that's the same as New Frontier). No issues.
Will this fit on other lowers- New Frontier, Spikes, etc- or just PSA? Is there any ammo it won't fire?

Love this upper.
Love this pistol. I shoot this thing way more than my other ARs. Grouped 4” at 100 yards free handed with a red dot.
