i was just looking over DSAs sale and got to thinking. hey you can build a complete 16" m4 clone for not too much bread with these lowers and upsers on sale.
DSA ZM4 Stripped Lower Receiver - DSZM4R-D S Arms
so i did the math
zm4 nitrite treated barrel upper $275
DSA lower blem $ 60
DSA LPK (i think these are LMT) $70
DSA 6 position stock kit $50
DSA SA carrier with bolt $110
DSA charging handle $18
total for a complete m4 kit including the lower $580-= s&h and transfer from ffl-for a DSA no less!
this is a very good deal for everything to build a high quality AR. quite a bit of savings for a few minutes it takes to assemble an AR-15!
first time kit builders need to get on this one!
