9mm AR comparison

I have it up on my site here with descriptions, captions, and conclusions. Here are the pics though. Other than the first pic, the Anvil Arms is typically on top and on left, the Colt on bottom and on right. The Colt was dirty, the Anvil was clean.

I don't do much with the 9mm ARs myself, but I like the idea of having multiple calibers available.

How often do you shoot with them?

[rob_s]

I'd like to shoot with them a lot more. However, just like .22s (but to a lesser extent) I think there are training pitfalls if you're not careful.

I mostly want one for training in environments where I can't shoot 5.56 and for a caliber that suppresses a lot more effectively and with subsonic ammo that's a little more potent.

My ultimate goal is to have one that mimics my primary SBR as much as possible.

Why are their gas keys on a 9MM AR ? Isn’t It blow back?

[rob_s]

"gas key" is a misnomer really. It's more of a guide to ride in the channel in the upper. Doesn't have the same function at all.

Exactly.. the "gas" key is really just a guide rail. There's no hole for the gas tube to go into. In fact it's cut short so it doesn't make contact to the gas tube.

I've been running a Spike's tactical 9mm LMT MRP CQB setup.. and it's great for using for places where they don't like "high power" rounds. Plus let me take my friends to try shooting a rifle but not deal with the hassle of the gun range requiring to be "rifle certified". Note this was on a 25 yard range.

Any case 9mm is a great round to practice on.
