9mm AR Build

[Sugar Land]

I didn't know 147gr would go supersonic from a longer barrel.

My reloads only show about 70fps difference from 5" ported barrel to 16" Uzi barrel, but I'm using a terrible powder for the application.

What kinda speed were you getting? Have you ever crony any american eagle 147gr?

 

[Tejano Scott]

Scott, what is your estimated cost, minus the suppressor and tax stamps (I already have my Eco-9...)?

I will itemize a list when I get home.

I was only getting 1000fps out of the 16" barrel. ~930 from the 5" barrel using 147gr heavy plated.


I was using 3.8gr Autocomp which isn't supposed to be good for 147s but didn't have anything better. Should have been mid range loads but barely cycled the XDm. Uzi ran fine. Haven't had time to play with any other loads.

 

[Younggun]

Haven't tried any AE. Will try it if I come across some.

 

[Tejano Scott]

So, back on topic.....(what has become of me?)

Are the 9mm ARs finicky with tuning or do they tend to work across the board with most ammo like a regular .223/5.56 AR?

You have to run very heavy buffers and springs to guarantee reliable feeding. The bolt hold open can also be tricky. Many lowers don't have the BHO feature.

BHO is over rated for Operators.

My gun stays in the night stand. If someone breaks in they can have it after they get through the alarm, 100# German Shepherd and the stay at home mom that has a gun within a few feet of her at all times. If they did steal my pistol and can I'll buy another one. I'm not restrictions my access to it in an emergency for the "what if" of someone breaking in.

Chuck has a stay at home mom guarding the house? How much did she cost?

 

[Sugar Land]

None of them are cheap..

I want to be very clear... You can definitely do this build with cheaper parts than I selected. Prices for the can have gone down considerably since I originally purchased. You can do cheaper parts, and even the same parts cheaper than I have listed if you have the resources. I'm lucky that my dad is an FFL, so I can usually get at least 10% off most parts I order. Here is the revised part list with EVERYTHING itemized.

GRAND TOTAL INVESTED (Including tax stamps, can, and optics): $3,767.80.

Please note: most prices represent MSRP. I didn't pay MSRP for all parts except the lower, barrel, bolt and buffer. Prices also do not include tax and shipping, except for the lower which includes tax and shipping.

Holy crap!

My personal Holy Crap moment came with a good laugh when I saw the gun is less than the can, stamps, and optics.

I was like this seems like a good idea until I saw the price. :-)
