I just purchased a new DPMS AP4. It's chambered for 5.56 and can obviously take .223 as well. The question I have is because it's actually chambered for 5.56 do I need to use that ammo to break in the barrel or can I use .223? This is not a "how do I break in the barrel" question, just what ammo to use initially. I'll be running .223 through it primarily moving forward.
Thanks in advance for your input! Skip |

Quoted: Run American made ammo, .223 or 5.56 and you will be fine. Just remember to lubricate the rifle before shooting; they are shipped dry from the factory.  Yeah, good rule of thumb for any new firearm... Clean off any of the dry lube or preservative stuff that's inside, relube with a quality weapons lube of your choice (SLIP2000, CLP, Gunzilla, Weaponshield, etc.) before shooting. |
| Thanks for the advice and it was in the plan. I'll be using 725 cleaner and Slip2000 and it'll go through a thourough cleaning prior to first shot and I'll be putting Federal American Eagle 223 Remington 55 Grain FMJ through it. I really appreciate the quick feedback and advice...you guys rock! |
