So I just finished up my new AR-15 and was wondering what if anything I needed to do before firing it before the first time. Grease parts up or something. Or if i can just go nutz??

I always check headspace on a new build and if/when changing bolts. Not really necessary, but it is peace of mind for the minute it takes me to do it.

Give the barrel a light lube aswell as the BCG

Do a function check on the trigger.

Could you explain or direct me to an explanation of this process?

don't use grease, use oil. any gun lubricating oil should be fine. i always use CLP. lube your BCG liberally the first time out. don't forget to relube when needed when you're at the range and have fired some rounds.

you need a head space gauge to do this. if your ar is using all new components or is a factory built rifle, i wouldn't worry about it.

you may want to face away from the rifle the first time you shoot it just in case tough. :p

I can't find this "AUTO" and "BURST" mode that they're talking about? :confused:

LOL :D

Like everyone else said, clean, lube and fire - then repeat!

Enjoy and welcome to the disease.:rockon:

You bet. Get a set of GO / NO GO headspace gauges from Brownells (http://www.brownells.com/.aspx/cid=36/Products/Headspace_Gauges). The GO gauge will allow the bolt to fully close. The NO GO gauge will not allow the bolt to fully close. It is not really necessary on a new rifle, but my eyes are worth a lot more than the $50 or so the set cost me and the minute it takes.

Like others have said, run through your function tests, lube up the BCG and have fun shooting it.

Most importantly, have fun shooting with your son.

+1000

I'm surprised this wasn't the first suggestion.

-Lube the BCG. Get it wet. They like it wet.

-Do FCG check (had a buddy who put a disconnect spring in their build upside down once. Don't do that. The trigger may not reset properly and soft primers can cause interesting and/or very bad situations if the disconnect spring is in upside down. You want the fat end down.)

-Shoot the hell outta it.
