If you can build the lower you can do the upper. It's not like you have to headspace it or anything. It's easy.

I'm fairly new to AR's (about 11 months). I'm more comfortable with building the lower right now than I am the upper. I would recommend build the lower first and see if you want to start building the upper, or buy the upper and get to shooting.
Yes I am definitely building the lower myself

What would be an example of a build that requires you to check the headspacing? Just curious

Just about any other rifle where you have to attach the barrel. On an AR it is set when they manufacture the barrel.

Well I have two BCMs and they're as good as a BCG gets.

I don't know first hand about the Noveske BCG but it should be good. Looking at three year old data from the old M4 Chart, Noveske at the time didn't high pressure test the bolt but did do magnetic particle testing. Also the extractor spring insert wasn't the desired black but that's a small thing (since an upgrade spring and insert is cheap and easy to replace). Otherwise the bolt was shot peened and came with the desired M16 style carrier. The gas key was properly staked.

Hopefully someone can chime in with current info but I wouldn't be worried about a Noveske BCG today.

Noveske BCGs are only marked MP. With that said, those who usually buy Noveske, generally run their rifles pretty hard, so you should not have any problems with their BCG.

Edit to add: Noveske does not just blindly throw BCGs into their rifles and uppers. They actually test fire each 5.56mm rifle and upper with Black Hills Ammunition before it leaves their factory.



Their is a relatively new company making rifles and components that has all the bells and whistles to their BCG, that may interest you. SIONICS Weapon Systems is based out of Arizona and they are bringing to market some high quality stuff at pretty reasonable prices. You can check them out at http://www.sionicsweaponsystems.com/

here are the BCG details:


100% HPT & MPI
Shot Peened
Heavy Extractor Spring
Black Insert and O-Ring
Nickel PTFE Carrier

SIONICS bolts are made by a current defense contractor from Carpenter 158 Steel. The bolts are 100% high pressure tested and magnetic particle inspected. Each bolt is shot peened and comes with a heavy extractor spring, black spring insert and O-Ring.

SIONICS bolt carriers are also manufactured by a current defense contractor. Only M16 bolt carriers are used. The keys are checked for a flat fit before being installed and the bolts are side staked.

Each carrier assembly is treated with a durable Nickel/PTFE plating which creates a permanently lubricious surface which eliminates the need for grease, oil or any wet lubrication.

That's what I originally planned on doing but then I came across a complete configuration with basically all the parts I had on my list and it turns out that buying it professionally assembled by Noveske (with a 7% off coupon code) only costs $90 more than buying the parts separate and assembling it myself. Seems like a pretty sweet deal to me

Yeah it's worth it to have Noveske do it. - That $90 could shrink fast especially if you're getting the parts from multiple sources and have to pay shipping for each order.
