Well I finished my cheap'o plinker/ coyote killer.  I still need new hand guards but other than that and a new scope its done.   The hand guards and scope were just laying in the parts bin in the closet and are better than the stock hand guards and no optics.  

I decided to put the bushmaster lower on the plinker and my stripped zombie spikes on my carbine.  

Went with palmetto state armory moe LPK, and A2 Stock kit, amd a DPMS lopro Classic Bull Barrel Upper.  Total cost 600. Plus shipping still need free float tube low gas block and new scope and mount but will be like this untill I get alittle over time.
