Hello Y'all.

I am a bit new to the AR15 world and very fascinated on how mosts parts from different manufacturers can work together.

Research has been taking lots of my time for the past month and I originally wanted to build an AR pistol but will build a rifle first.

I walked into a local gun store to see what AR parts they had in stock.  The sales guy showed me a Mega Arms Billet M0903 set and somehow my head was telling me I had to have it.

To me, it is a very nice pair.  But after doing more research, the money spent could have been more useful somewhere else.  I am an impulsive, emotional buyer.  LOL.

I have many parts coming from everywhere and should all arrive within a few days.

Looks like a pretty good component list.  I'd add a different charging handle, but that's just me.

You're gonna love this set. Sounds like a good build already. I also went with mega.

Thanks everyone for the encouraging words.


Deangelo1290, by your list, it looks like you have a very nice rifle.  Some of the brands I have never heard of.  I will look up your components and your barrel recommendation.  

SJuhockey10, what charging handle would you recommend?  By a simple google search, it leads me to BCM charging handles.
