From TKS Engineering, this is a hand matched billet receiver set. This is the version w/the integrated trigger guard and American Flag engraved on the front of the magwell. It is a beautiful piece of work. I had intended for this to be the platform for a precision AR build, but I'm now considering building something in .308. The current 500 meter champion won using these receivers. These receivers lock up TIGHT, you literally struggle to separate them. Yes I know how upper/lower receiver lockup has little to do w/accuracy, but it shows the precision in the machining. Asking $420 FTF in WA and that INCLUDES the installed DPMS lower parts kit.
