Ar-9

[Magdump]

I'm so used to people slapping there sights on backwards "because it's better that way." A lot of people do it on purpose with MBUS sights.

I actually thought the front was better folding forward and I reckon I just mounted the rear to match. But yeah, they definitely bass awkwards! Lol

No real issues with mounting the front backwards, since it's just a post. The problem is the rear sight. If you were running an optic with it, such as a red dot, you wouldn't be able to flip up the rear if it were backwards. The other issue is the rear aperture being backwards, but that's just me being nitty.

My 9mm set up

I like that. What lower/upper did you go with there?

DDLES lower, CMMG upper receiver, Tros barrel, Tros 3 lug adaptor, AAC TRAID, AAC Evolution 9mm, Seekins MCSR 10 inch rail, spikes st9x buffer, and geissele trigger. All functions together flawlessly.

Spartan upper and lower(glock)
New frontier bcg and barrel (4")
Kak shockwave blade and buffer tube
Jp silent captured spring 9mm
Jp 3.5lb trigger
Phantom flash hider
Magpul k2
Qd butt plate

Had to drill the rear part of new frontiers modular bcg to allow the silent spring to work correctly, i have to have that buffer set up so this step could be avoided and for less money.

Got a lot of part from job bob outfitters and Amazon
This setup 1000 dollars

Nice. Looks great. I really dig the side-charger. Who made that?

I had issues with reliability with mine until switched the buffer to a spikes ST-X buffer and wolf spring. That solved my problem. Mine is a CMMG MK9 with a 4.5" CMMG barrel and Sampson evolution rail.

I had the same set up, but recently switched out my rail in favor of the MCSR to be longer, since adding the 3 lug added a little extra length to the whole set up.

It's the side charging 9mm upper from MAS Defense.

He texted me when he was ordering it and when it came in lol

Quarter circle 10 is the way to go.
I've built a few on double diamond lowers both Colt SMG Mags and glock Mags, loved them both.... They had a good product but didn't know how to run a business.
Quarter circle 10 basically just bought the rights to their design and took over, same quality product and a whole lot better customer service.

Easiest rifle I ever built! Just pushed 2 pins.
It's a very sweet shooter. Not one
FTF in over 300 rounds. Feels like 5 pounds loaded. Thoroughly enjoying it and have yet to
Tweak the trigger or change the grip. Been too busy shooting it!

What length barrel and rail? Just picked up a 9mm lower and I am trying to decide which upper to go with.

That's PSA's 10" but I'm waiting on the 7" as well.

It was from MAS defense like Dave_m said. I picked it up while they were on sale a few months ago.
