Need advice on 2nd 300BLK SBR Build
Posted: Sun Nov 15, 2015 12:10 pm
Hey guys,
I've gotten the bug to build a 2nd 300 BLK SBR. This SBR will become my primary SBR and my original build based on an AAC 9" upper will become my secondary gun (primarily because I kind of hate the billet lower I used in that build).
One impetus for this is that I think that we will see changes to rules around NFA Trust before the end of Obummers 2nd term and I'd like to have at least one more SBR before that happens.
So here's what I'm thinking I'm going to do as this will be the first time I try to build an upper myself.
1. Aero Precision M4E Enhanced Upper. This upper is specifically designed to ease barrel and hand guard installation. The only drawback is it can be a little trickier to get the gas tube lined up due to the thicker interface at the barrel nut. Well, there is one other very small drawback which is that this upper has slightly different surfaces than "standard" uppers and might not fit tools needed if I ever wanted to fit a 6.8 barrel or do certain other things with the setup that I am not likely to ever do.
2. Aero Precision lower.
3. Aero Precision 7" M-Lok or Keymod hand guard... all of my other stuff is Keymod but it might be kind of nice to check out the competition for this build and since swapping the hand guard with the M4E upper is super easy I can change it out later if I like for about $130.
4. Noveske 8" 300 BLK barrel. My LBS will sell me this barrel (which includes gas block and gas tube) for $275. I don't want to cut corners on the barrel but if anyone has what they feel is a better choice I'd love to hear it. I've contemplated between the 8" barrel or going to a 10.5" since I normally prefer a slightly longer hand guard so any input here is welcome.
5. Regular stuff for lower parts kit, buffer tube, etc. I will actually re-use a spring/buffer setup from my 1st build as I ultimately replaced it with a captured buffer.
6. For furniture my current go-to setup on my other carbines is the BCM grip and the Magpul MOE SL stock. I love that stock and have it on three of my rifles now.
7. To make things "fun" this time around I think I might do the upper/lower in black and then do the grip, hand guard and stock in FDE.
Interested in any input anyone can provide.
