Two
Read  the Troubleshooting Checklist announcement at the top of this Forum and check your rifle against it. Read the FAQ.

Three
Read the TM and understand it. Many problems with FrankenARs are related to improper assembly. Modifying correct parts, or using non standard parts, is ALWAYS a last resort here. We try to fix the problem not the symptom.

Four
If you are not using USGI mags and USGI ammo, we will tell you to try them and get back to us. Only post if you are certain the problem is not with your magazines or ammunition. Information on both is available in their fora.

Five
If your rifle has a warranty and you have no background in ARs we're probably going to tell you to send it back. That is the only way the replicators will learn to do it right. Do yourself a favor and use that "customer service" and "life time warranty" you paid extra for. See Rule Nine.

Six
Post a complete description of the rifle, the ammo, and the malfunction. Brand names are helpful and pictures are a plus.

This forum is not the place for "Who makes the best AR?" questions. If you’re looking for an arguement go over to EdSr's place and run with the big dogs.

Eight
The further your rifle gets from the base design the more problems you're going to have. The more modifications you make to your rifle the more problems you are going to have.

Nine
To avoid problems with ARs buy one, as directly as possible, from either Colt , RRA, or Bushmaster. Due to the amount of bad parts out there and the myriad possible combinations, building your first one from the ground up is a bad plan.

Ten

It's your rifle, your money, your life, and, ultimately, your decision. Free advice is worth exactly what you pay for it.
