Amazing upper - Daniel Defense DD4 RIIIS URG 11.5 inch 5.56x45mm NATO Upper Receiver with Flash Hider Assembly

I slapped this on top of a cheap but well made PSA lower and put a radian trigger, safety selector and charging handle I put a geissele h2 buffer and spring in the buffer tube and my pistol shoots like a dream. Very accurate for an 11.5 it was between this and a Geissele mod 1 but the Geissele was out of stock so I went with this and boy I am not disappointed at all with my choice I like this better because I was always a big fan of the mk18 so this feels like an upgraded version of it.
