Is that a good combination for an AR15 build? Any specific uppers from BCM for a carbine. I was looking at the socom upper. Yes...or just find a BCM complete lower with their Gunfighter stock. Their M4 SOCOM upper is the best (I own two) and BCM runs a free BCG deal with a purchase of an upper, but I haven't seen that for a while. http://www.bravocompanyusa.com/BCM-Standard-14-5-M4-SOCOM-Upper-Receiver-p/bcm-urg-m4-14socom.htm |

Whatever you decide you like should do exceedingly well for you. |

I'll hopefully be mating my aero lower with a BCM upper tomorrow!
Went the aero route as I refuse to pay $400+ for a BCM lower or $375 for a blem BCM lower (will snag one when I find one at a reasonable price) Snagged a compete magpul aero lower on sale, and have heard good things about the fit and finish! |

16" for no pinned muzzle, 14.5" if pinned is ok or you want to go the SBR route. The socom profile is thicker under the hand guards and it makes a lot more sense than a government profile which is thin under the hand guard. Socom profile barrels tend to shoot a bit better in my experience also. Socom on top. Now when you say pinned muzzle are you talking about the compensator from BCM because on the website it comes with it installed on a 16 inch barrel https://s12.postimg.org/hzd2y1pzx/IMG_2702.jpg Quote HistoryQuoted:

Any rifle barrel under 16" overall length makes it a SBR. So the way around that with a shorter barrel is to pin and weld the flash hider or compensator in place. BCM sells their compensator and a standard flash hider in extended lengths to bring a 14.5" to 16". If you get the 16" barrel you don't have to worry about any of that.
The pinned muzzle device makes changing out rails in the future more difficult. So if you get a pinned upper, make sure it's how you want it before it's welded in place. I do not have any pinned barrels for what it's worth. |

Then you're fine. But if you wanted to put a different rail on it, and it used a different barrel nut, the weld will need to be ground off which typically destroys the muzzle device in the process. Quote HistoryQuoted:

And on that other comment if I get a 14.5 from BCM I won't have to worry about it being a SBR since the muzzle device will make it 16 inches. Dont need the hassle of owning one.

Great upper, but I didn't like the limitation and I had an SBR stamp several months later so it made it pointless. Spend the money on pinning/welding on a tax stamp instead or just go 16, thats my experience. |

I like pinned 14.5's. I don't worry about changing things but if I did, there are nice rails out there that use the mil-spec barrel nut and cutting down the fsb into a lo-pro gas block is easy enough.

I like to step down a level for my lower vs the upper. It's for money savings only though. I view the lower quality as less critical as long you still get something if good quality. $400 for a lower setup with all the desirable doodads will be right around $400. For BCM, I'd actually consider it a good price. That said I won't put disproportionate money into my gun. If it's a cheaper one, I'll be damned before I put tons of money into a high-speed handguard or stock. Etc. Lots of people with way more money into just their handguard or stock than their irons/optic. |
