Daniel Defense DDM4 V7P, 5.56, 10.3" no issues of defects, works like the day I bought it. I'm also going to throw in two Magpul magazines in addition to the Daniel Defense magazines. The iron sights are from Midwest Industries. As for the ammo, I'm not sure exactly how many rounds are in there, but I would estimate 50 ~ 90 rounds more or less. However, there are some soft point rounds in there for home defense.
