I have like new, perfect condition Spartan Billet 9mm/45ACP Non-Reciprocating Side Charging AR upper receiver. It doesnt have a mark on it. I built one for myself 2yr ago and it is by far the most fun gun that everyone wants to shoot. Especially with a can and 165gr subs on steel. My son was constantly hogging mine at the range so I decided to build him one. I put it together, and he never shoots his. It has less than 50rd through it and you would never know its even been fired.
You can build this upper in 9mm or 45 ACP (I have 2 of those, one in 9mm and one in 45 ACP).
This upper has the Last Round Bolt Hold Open feature. I run Glock 33rd mags.
Works great with Toolcraft 9mm BCG and I use Wilson 9mm 7.5" SS barrels from JSE Surplus.
These go for $300
SOLD
