Hi everyone I am new here and this is my first post.
I recently purchased a new DD V4 and have had feed problems after firing my first 4 rounds.
I started with the remington 55g .223 umc and began to have problems with the rounds cycling, they eject fine but when the next round tries to chamber they wedge in a 30 degree angle. Next I tried some 55g .223 USAmmo, it was slightly better but still wouldn't feed right. Next I tried some surplus 55g .223 UAE ammo, no real change there either. Gun store guy I bought the Gun from, ( which he ordered through Daniel Defense in Georgia) says try some Federal 55g 5.56, all 20 rounds cycled perfectly. Next I tried some Winchester 55g 5.56 and started to have feed problems again.
Anyone had any similar problems with M4's? By the way I did use two differant style magazines during this time, so I eliminated the mags as the problem. Any help would be greatly appreciated thanks.
