New member here and new to AR's. I have started my first build/pin project after lurking and reading many threads on here. I am looking to build an AR for HD, SHTF, and just overall fun rifle to shoot.
I am purchasing an Anderson stripped lower from my local FFL. I have ordered PSA's CTR lower build kit and 2 PMags for the build portion. After receiving my tax return, I will be ordering BCM's BFH 16" mid LW upper receiver group with KMR handguard. I still need help with choosing sites. I have read many people recommend the MBUS and many others. The MBUS seems to be good for the price but what else is there? The KAC seem very steep in price. Then comes lots of ammo and many more PMags. After I get my project functional and have put many rounds through it, I will add some basic accessories. I am thinking of adding an angled fore grip, a basic light (Streamlight ProTAC HL?) and mount, a real good red dot (T2/T1, etc.), and maybe a magnifier for longer range (100 yards). I haven't researched slings yet but I am sure that should be added to the list to finalize my project. Your thoughts and recommendations? |

What's the major difference between the BCM BFH and SS barrels? IS the SS more durable, accurate, corrosion resistant at the cost of added weight? Just asking because the original 16" BFH middy LW I wanted is no longer in stock but the SS barrel is. Generally, BFH (= Cold Hammered Forged) barrels have a longer service life while SS barrels are more accurate. Here's the rub though: individual barrels are different with respect to accuracy. |

So BFH is better. Figures!  I guess I could do a 14.5" barrel but I am not sure those are legal in Florida. I think that falls under SBR which requires a Class 3 license?That's a federal statute, not a state one, though some states take it upon themselves to ban certain classes of NFA weapons. Get an appropriate length flash hider/comp and have it pinned to give you a legal >16" length. |
| So I can do the 14.5" BCM LW BFH mid with KMR and add the Surefire MB556K and be gtg? Would this be a good set up for a first timer for HD and longer range 100/200 yards? I am assuming the 14.5 would be better for maneuverability in HD vs 16. The 16 would give you a little longer range vs 14.5 or is it more about the limitations of the 5.56 as far as range goes? |

Quoted:Would this be a good set up for a first timer for HD and longer range 100/200 yards? Sure, though I'd probably go with a flash hider instead of a brake, but that's largely preference. The recoil of the 5.56 is pretty low and doesn't warrant the greater noise and blast that a comp causes. Quoted:I am assuming the 14.5 would be better for maneuverability in HD vs 16. Yes, slightly. Comparing a 16" and a 14.5" with the same FH will probably only gain you 1". I have both and while it's worth it to me, others disagree. Keep in mind that unless you're going to SBR a lower you'll have to pin and/or weld that Surefire, so it isn't coming off without some work. Something to consider if you like changing stuff out. Quoted:The 16 would give you a little longer range vs 14.5 or is it more about the limitations of the 5.56 as far as range goes? I think there's like a 75fps loss with a 14.5". Negligible for your ranges and uses. Many will tell you that you can make repeatable hits with a 10.5" barrel at 300-500yds. Good luck on your build. |

See Barrel Length Studies in 5.56 for velocity difference between 14.5 and 16.0 (and other lengths). To me, the velocity difference is negligible and the quality of the barrel is far more important. At 500 yards, the difference in drop is ~7-8 inches. You might want to consider a flash hider instead of a brake. Then, consider it some more the more often you shoot indoors and in the presence of other people. 5.56 with a brake is loud. Not long ago I failed to double-up (plugs + muff) my ear protection while shooting a SBR indoors and I'm now paying the price--for the rest of my life. |
