Finally, I built a complete AR

AR/M4 Custom Build Forum

Well I’m almost done… I was intimidated for a long time to put my own AR together, for the reason, I didnt know that the barrels were already headspaced when you bought them(theoretically I know). I had no Idea is was as easy as it was. well I did have one little problem.

Parts list:
Mega lower
RRA lpk w/ RRA 2-stage trigger
magpul trigger guard
BCM forged buttstock tube w/castle nut
Magpul ACS buttstock
Mega M4 cut upper
RRA Bolt/carrier (for now its out of another rifle but its only got a few hundred rnds on it, BCM in the near future)
Daniel Defense 1/7 m4 16" chrome lined 4150 (169.00 dollor deal)
YHM low pro/short gas block
BCM gas tube
A2 flash hider (for now)
BCM Gunfighter charging handle MED
Midwest Industries MI-T12 hand-guards
standered grip (for now)

What I need:
Sights–maybe MBUS?
red-dot?
short scope like 1-4 or? I already have a bull barreled scoped upper.
New grip?

feel free to make suggestions.

I really like the MI-T12, it is VERY light and locks up solid with a nut on the underside that goes inbetween the grooves of the barrel nut. So it is as anti-twist as the barrel nut…The problem I had was the handguard hit the reciever on the final turn JUST barely so I had to file a miniscule amount off the face of the little tab that hits the reciever. After I delt with that, it was easy breasy.




I wanted to add:

I used a DPMS armorer’s wrench to tighten the barrel nut and the MI jam nut… I just had to grind away the right radius of the jam nut for it to work.

Looks great! How did you like working with that Mega receiver set? any fitting required?

I like the finish quality and the rollmark/engravings of the Mega, no fitting required. There is actually a little bit of play between the lower/upper which I was slightly dissapointed about. Its not too bad though.

These are all with Iron sights @ 100yards @ dusk in 28 dgree weather,lol… I suck @ irons…bad… I couldnt see the orange dots at all… I will deffinatly report back when I do better.

not bad. but wow you missed the target badly…:stuck_out_tongue:

Its all in your tringer finger. But at dusk and 28 degrees!! I might have trouble with shooting good groups at that temperature too.

sorry I forgot to reply sooner…

I was shooting @ 100yrds off the bench on a cloudy day around 300pm and I couldnt see my shots through the spotting scope when I was shooting in the black, so I started shooting in between the black targets so I could see where my hits were from the bench.

The orange dots I could just barrely see anyways… but yeah, Ive since gotten some better groups. when I get some really good ones I will take pics again.

I was out last weekend shooting the rifle @ 340yrds and was getting hits almost every shot on a 14"x14" metal plate… I was very pleased.
