I am very well pleased with my short, light, DPMS LR308-AP4.
the 16 inch barrel and telescoping stock make it as quicdk and easy to handle as an AR-15, M-4.
It is only 12 oz heavier than the same rifle in 5.56X45mm.
The soldier's pack is not so heavy a burden as the prisoner's chains. Dwight Eisenhower
