I dont remember everything in this build but
SJ Hardware 18.5" 223 wylde barrel with my home made brass endcap for bling
Daniel Defense bolt carrier group
Giessle 2 stage trigger, ssa? The expensive one anyways.
Ergo grip, hand guard was TNA i believe
Magpul stock
Colt parts kit, ambi safty
BCM charging handle
Troy sights
Everything was bought second hand except the barrel and parts kit. Total cost approximately 2250 maybe 2400 tops with shipping costs.
Add another 1500 or so for optics and rings by the time it is done and I'm at 3900 tops.
