Quote HistoryOriginally Posted By Trunkmonkey4: Dumb question, but looking at drawings the difference between f marked and non f marked is not much. I have an f marked carbine barrel I want to pare with an a2 upper. This as simple as adjusting the front sight post, or am I better off replacing? I think you could use the shorter threaded front sight post. Someone smarter than me can correct me if I'm wrong.

Just got my RRA A2 upper in this morning. Very nice finish and it DOES have me feed ramps.

I'm glad my A2 Upper had the feed ramps, I value function over authenticity.

Newbie question here. Im looking at RRA website right now for an A2 assembled upper and i notice they have 2 options with about 50bucks difference.
Which upper would be best to get? Thanks. |

One has standard and the other has national match sights. The NM sites have finer adjustment and a hooded eccentric peep that can give another 1/2 moa of fine tuning. Google national match A2 sights. What is your use case? What are you planning on doing with it? Standard are fine for non-match use. |

Thanks for the reply.
Yeah im not gonna go use it for match or any of that sort. Just wanted to build a BHD/ Blood Diamond looking kind of piece. So the regular one is probably best for me. Will a 14.5inch colt m4 barrel be okay to pair on this upper? Besides the colt m4 barrel, any other barrel i need to consider? Thanks again. |

Often you will see those with the side that faces in towards the receiver trimmed flat so the shape is a D. That was done for clearance with the new A2 profile lower receivers, if you leave them circle shaped, they bind up and won't work properly. |

any feedback on RRA stocking and shipping process? i just "accidentally" ordered the a2 assembled upper and a 14.5 chrome-lined R4 barrel but found it weird that they didnt say how much for shipping. (TBD-to be determined?).
How's their barrels? are they good enough for light to medium use? hope i didnt make a costly mistake.

I just placed an order a week ago for over 400$ of small parts and kits. Got a shipping notification 2 days later and package arrived quickly. Shipping was $33. More then what I would consider economy or ground but probably on par for expedited. At least you know exactly what you will be getting. |

Pretty quick too, ordered on Sunday and delivered on Wednesday. Also ordered a PSA M16A2 blem lower, that should arrive at my FFL today. Also have a light weight 16” carbine barrel coming from Del-Ton. Gonna do a late 80’s early 90’s Delta’ish clone with a Aimpoint 2000 and Surefire 660. |

Got my M&A order yesterday. First time I dealt with them but they were great. Fast shipping and good service. I ended up placing two orders. I ordered my upper and some sight parts, then later realized I needed a Delta ring assemble and some other small parts and placed another order. I was just going to suck up the extra shipping since it was my fault for not ordering all at once. The next morning I saw I had a shipping refund on the second order and they sent me a not saying they saw I placed two orders so they combined them. I thought that was awesome.
Anyway, here's the upper. It looks good. It does have M4 ramps, which was fine for my project since I'm doing a carbine and the barrel has M4 ramps.  Attached File Attached File Attached File |

The ejection port cover spring is the proper silver color, the US-made-looking rear sight assembly is nicely centered in the channel without excessive wobble, the interior is coated in gray dry film lube, and the m4 ramps look adequately deep and uniform. This looks as nice as any in-spec A2 that I have had in the past. This upper will be replacing a flat top upper on a new Colt 14.5" M4 upper assembly with an unmarked, F-height, FSB. Going for a 777ish build. |

placed an order for an M&A too. couldnt wait for the RRA and it seems nothings happening with that order to the point where i canceled the barrel i ordered together with the upper for a much cheaper one with Luth-ar. if the RRA comes thru then good, if not im sure ill be okay with the m&a.
so you guys just using a milspec buffer system or can i slap a BCM MK or VLTOR a5 system on it without looking funky? which repro CAR stock has better fitment? B5 or H&R? |

I'm just running mil spec on my various builds.
Not sure on the fit between those too. The only CAR stock I have is from TNTE. I have either regular M4 stocks, various Magpuls and a few other things, or fixed stocks on my other stuff. |

MA Parts has a damn nice repop CAR stock. Last I knew though you have to request the milspec type latch plunger assembly as many were selling with non milspec components. |
