I am wanting to build a 18" AR that is sort of a SPR type rifle. I have been looking on BCM at their offerings in the 18" 410 SS uppers. I also found this on Palmetto State Armory.
Link Seems like a good deal, but I am torn as to which direction I should go. I am not a precision shooter but want a rifle that is capable of higher than average accuracy. The PSA is a CHF heavy profile CMV steel, and the BCMs are the 410 SS. How much difference in accuracy does everyone think there is between the uppers? I will be using a scope (have not decided what yet). Also, are their any other assembled uppers I should consider for this role? Not looking to build my own here (have in the past but lazy  ).
Thanks for any insight. |

PSA and BCM are cut from a totally different cloth. I don't see how you could be looking at BCM seriously and then switch to PSA.
Part of BCM, and the reason people buy them, is because they are built TRUE milspec +. PSA isn't built to any standard much, other than if it doesn't work, they're CS will save you. So if you wanted a true milspec rifle, you;d look at BCM and ignore PSA. If you were looking to spend less, you look at PSA and not BCM. Just off that though, I'd say PSA is probably the one for you. |

I have a new PSA-from-the-Easter-Sale CHF 16" Carbine upper. It shoots OK, about what I'd expect from Iron sights and xm193 ammo. 3-3.5 inch groups. Now I drop the XM193 into my 16" BCM 416 stainless Ionbond barrel which is mid gas (1 in 8 twist to be fair, not the 1 in 7 of the PSA) and I can shoot 2" groups easily. All day. This is with a red dot, so a bit of apples to oranges comparison. Take from it what you will.
Now, If you want to talk accuracy I have a new Ranier Ultra Match 20" SDM coming, Shilen blank, 4 ratchet rifling, finished for Ranier by WOA (contour, flutes I believe). It's on the way from Primary Arms, and will be mated to a Vltor MUR-1A. I expect great things from this setup, or I will return it as unsuitable to Ranier. Gonna have an SSA-E from the EE as well. If it will someday be used as a SHTF gun, get the CHF barrel. If you want extreme accuracy, chrome lined is not the way to go. Are the BCM's midlength gas as well. Rifle length 18's are more my style or intermediate-length gas, which is supposedly perfect for 18 inches. |

BCM has a outstanding reputation for product and customer service. PSA has a reputation also. And if you pay close attention you see BCM problems and complaints before the threads are locked or deleted never to be found again. They have their share of issues.. Here's one you most likely never heard about. Click link quickly before my post gets deleted. http://www.m4carbine.net/showthread.php?152251-BCM-firing-during-trigger-reset |

If you don't mind a 'blem' upper, BCM has a deal you can't beat right now. $329 for an M4 upper minus BCG/charging handle.

You actually believe that the incidents of "mishaps" for the two are equivalent to one another? BCM is not perfect, and there will be problems here and there. But I believe that theirs are few and far between compared to others. And I certainly don't believe that there is any motive to subvert anything. |

No, all manufactures have their share of issues. Is that hard to understand?
And when one points out a issue with certain manufactures they get bullied online. One can talk about PSA or Colt without reprisals. Yet another reason you don't hear all the problems with certain companies. Here's another. I got a whole lot more too. http://www.ar15.com/forums/t_2_138/220298_Broken_Carrier_Key_Screw.html |

To OP...check JSE Surplus. They have a very wide range of complete uppers...some in stock...some not. If you order one of there custom builds it is very quick...less than 3 weeks.
I purchased mine from them after making several calls to them with questions. Every call was answered by a real person...no machines. Very nice and knowlegable and willing to help. They get A+ for customer service from me and with all the threads I have read recently about peoples problems with uppers they purchased you may want to check their site and give them a call with questions. |
