    I'm thinking about buying a BCM upper & rock river lower. Does anyone here have this setup? If so, are you happy with it & how well does the fit & finish match up?

    Why would you even want to put a RR lower on BCM upper??
    If your looking to save $$$ buy a blemished BCM lower and put in a 2 stage trigger.

    This. Like putting a set of $4000 wheels and tires on a 1998 Grand Am with 150,000 miles.

    I can get a complete rra lower for $325. I would like to buy a complete bcm but can't find the price of them & can't reach them on the phone. Another option is a colt le6920 at a local shop that came with magpull stock & grip . It also has quad rails from colt for $1300.00 out the door. Is this a fair price?

    You know that you can get a BCM blem lower for $269, a 1st quality BCM lower for $340 and a first quality BCM lower with a Geissele SSA trigger for $505. Just sayin.
     
  6. What makes the RRA lower subpar?

    TIA

    It's not. Lowers, generally speaking, are the same. What's much more important is the uppers.

    Can't think of any reason a RRA lower would be any different than most lowers.

    People who think putting a RRA lower with a BCM upper is "Like putting a set of $4000 wheels and tires on a 1998 Grand Am with 150,000 miles" are pure Kool-Aid drinkers.

    So long as the lower is in spec, the parts matter a LOT more than who made the lower - especially your trigger group.

    Nothing particularly wrong with an RRA lower, but a BCM lower isn't much more.
     
  12. While barrel and the front sight parts look ok on my vintage (ban era) RRA I deemed it a good move to swap out the bolt carrier group and rear extension tube. The lower looks ok to my untrained eye - was just wondering if there was some technical weak point in the lower.

    And if the OP has the option by all means get Bravo Company parts.

    Thanks again.

    Not sure why anyone would spend $325 on a RRA lower when you can get a BCM Blem lower from GandRtactical for $269. Nothing against the RRA because i'm sure it functions fine as lowers go....but seriously.....BCM man. Look harder.

    I always buy matching upper/lowers when possible.

    I bought a blem BCM lower last year, 3800 rounds fired thus far, not a single issue.
    As for the blem/s.....I did find a few very small punch marks near the pivot pin.

    ^^^ There, I fixed it for you:faint:


    To the OP:
    While, My RR lowers aren't attached to my BCM, the finish doesn't match up well and they have a notoriously tight fit to the uppers I have attached them to. I have had them for a number of years, before Bravo was all the rage, so maybe fit/finish has changed some over time.

    RR makes a fine LPK. They only difference I can really think of is RR uses a commercial receiver extension, or at least they use to. Also, the castle nut won't be staked on a RR.

    All that being said, get the blem BCM for less $$$.

  16. A+ on the BCM blem or regular, for a few bucks extra.
    Nothing bad to say about the other lowers, but
    I like mine matched and BCM has great customer service.
    If I already had the lower, I'd stick the BCM upper on it
    no problem, but if I had a choice, I'd match them up.

    Follow this advice...get the blemlished lower, if not get the new lower without the stock (you will probably want to change it anyway).

    And those that don't think there is anything different are drinking something "other than kool-aid".
