    Why buy the parts separate? If you are not doing the actual build just buy the complete rifle...

    If you are building a lower the RRA is not a bad choice. What you need to decide is whether you really need the 2 stage trigger for plinking, it adds cost with little benefit at shorter ranges for the average shooter. Some people just like the feel of it, that's a personal choice.

    Another decision point is the stock. A collapsible stock is nice if you need variable length of pull for body armor, CQB, etc. For offhand or bench shooting a standard A2 stock gives a better cheek weld and a more stable hold; you ever see a hunting rifle or a sniper's rifle set up with a 6 pos stock?

    One more thing to consider, do you want a carbine? Again you are giving up long range accuracy for transportability. A 20" bull barrel with a free float fore-end and a mid or rifle length gas system will outshoot a carbine all day long. It will be a bit heavier and bulkier but thats the trade off...

    Hope I've been helpful...not trying to sway you one way or the other, just trying to help you decide based on what you want to do.

    For a lower I second what MJ linked, the BCM blem is a great deal and is built right. The receiver extension is milspec diameter so you don't get painted in a corner later (I think RRA uses the commercial diameter). You can get BCM's M4 stock for another $20 or could leave it off and buy a MOE or CTR instead.

    His linked uppers are top notch too but as you said you're not ready yet to decide on that.

    as far as an adjustable stock, i want one because alot of people shoot my firearms there for id rather not see my 1100 dallor ar15 get dropped on the ground cause itsa a little long for smaller people or girls. You guys are giving me the feedback i was looking for with out some of the ****ty comments like others so thanks guys. after reading some comments, what should i be looking for in a lower? build or buy compleate. sounds like most of the building of an ar is from the lower? should i reconsider and just buy a compleate ar for my first and start building a BA one for later?

    If you are handy and think you can build it all from scratch, the yes do it that way. The feeling of pride when you tell peple that "I built This" is pretty cool but the best part is you start learning how the gun opperates right from the start. Lear all the components and then you get the itch to buy other components.

    Here is a great link on building one and one everybody who is doing this for the first time should have bookmarked: Parts List and build instructionss


    Good luck, have fun and post pics of your build.

    The first thing I would do is take a look at the Stickied Threads at the top of this section. You will find several very helpful threads, some of them from people exactly where you are now and the builds they ended up doing themselves.

    Of the parts you listed I don't see a reason to spend the extra coin on a NM 2-Stage trigger in a 16" Entry style gun. You aren't getting the true benefit of the 2-Stage as it's designed to be more of a target/varmint/tactical shooter support style trigger. 18", 20" barrel, longer range sort of thing.

    MJ and Quentin love BCM, so don't be afraid to check them out, but don't narrow your focus too hard, it can cause eye strain. ;)

    As for what to look for in a lower. This has been discussed quite a bit, but as I like to poke the Interwebz Trolls, I'll say it:

    A lower, is a lower, is a lower. Unless the lower is made from scrap lawnmower parts from Cletus' Garage and AR Accessoriez, you are going to be getting a simple part that holds all the components together.

    I have said before I could build a lower out of plywood and get the gun to fire. Durability would be a problem, but really all the lower does is hold parts in close formation.

    There are three types. Cast, Forged and Billet.

    Billet is the most expensive, the most coveted and the biggest OVERDONE of all the lowers. They are the Ferrari.

    Forged are pretty much the most common. They are everywhere and more like the F-150.

    Cast is kind of the taboo, is it or isn't it, element. Opinions vary with this one, but if you get a good one, it will be fine. If you get one of the last ones they made before they scraped the mold and started a new batch run.... well, maybe not so much.

    Here is a very good write up between the Forged and Cast done by Olympic Arms. Yeah, those guys, the ones that will leave you dead in a ditch if you buy their weapon according to SOME websites.

    Olympic Arms, Inc. - Is my receiver cast or forged?

    Good luck with your research and PM if you have any questions.

    Id at least purchase the upper this go around.

    Like everyone I was nervous my first time. I just eased in slowly then next thing you know I was pounding away. With my rubber mallet that is.

    The hardest thing about assembling a lower is not loosing an eye and one of those small springs. I suggest a sterile environment. Maybe remove the furniture, carpet and any framed art work from the room you'll be doing all the work in. I just found a spring I lost last year under my desk, how the...

    The thing w/ purchasing a lower from BCM is it'll be torqued/staked properly and the materials are of the highest quality.

    Save yourself a little money and purchase the upper and lower separately.

    Remington,

    I certainly do not want to contradict my brothers here on the forum because of their vast knowledge of the topic. However we all have our own preferences. I personally do not want anything in my ARs other than the RRA 2 Stage Trigger if I have a choice. For example all 25,000 of the DEA-FBI-and the other government agencies that have the RRA Gov. 1001 Rifles have the 2 Stage. If you ever shoot one you will be ruined! I know my dear friend Dillinger and some of the guys can do miracles with a single stage. The other issue regarding buying the RRA Receiver complete is the Ltd. Lifetime Guarantee. I if is a complete assembly it has the same guarantee as a complete rifle as well if you get a complete upper later.
    You also might want to look at the Predator Pursuit or the Coyote Models. Nothing wrong with the 16" Tactical Rifles if you are looking at 200 yards.
    I have a 20" Varmint that is when I am having a good day? A 1/4-1/2 MOA Rifle depending on the old man on a specific day. Finally there are a lot of good rifles and options out there but you could never go wrong with a Rock River.

    Shooting style plays a big part in it as well. I'm not a huge fan of setting up the shot. I'm more into the marksmanship of putting as many rounds into multiple targets as quickly as possible. Its probably influence from past training I guess. I have the up most respect for the guy that can exhibit the patients to set up the long range head shot however. They are both require a high end skill set. I just find more of a thrill in running and gunning. Plus its closer to what most of use would encounter should things pop off. Ill admit I need to push my boundaries a little.

    Well I just called my local gun shop and they specialize in ar parts and building them. I'm going to take a ride up there and take a look and possibly buy a lower and start slowly building it over a couple months.. my next question would be single or dubble stage trigger? What the benefits of haveing a dubble stage?

    To me a decent single stage is fine but not all military triggers are equal. I like the standard trigger in a Stag LPK.

    Nothing wrong with going two stage, take a look at Sniper03's post above. We all have different preferences so you might want to try both types in a gun shop before choosing.

    Quentin is telling right! It is a personal preference issue and you need to try both to see which one you like. I like the two stage per your last question for the following reasons.

    1. It has a 1lb. Free Travel on the pull followed by a 3 1/2 lb let off.
    2. This causing the trigger reset also to be shorter and faster. You only need
    let the trigger go a short distance forward after firing the previous round
    and you are instantly ready to go again. That was why the DEA and FBI
    chose that trigger due to control and speed.
    3. Which relates to total trigger control and you know exactly the second the
    trigger is going to fire.
    4. Also fast follow up shots and normally helps improve accuracy on precision
    shots when you want that extra accuracy.
    I am not saying that a good single stage is not accurate. But as stated
    there is a broader margin of weight and function from one single stage to
    another from the factory either in a complete rifle or in a kit purchase.
    5. The Rock River 2 stage is prepared for rifles or for individual part sales by
    an armorer at a bench and is simply a drop in if using the standard mil-
    spec trigger and hammer pin hole receiver.
    If you are going to build a lower receiver sometimes it is cheaper to get the kit with the standard Trigger and Hammer and then shop around for the RRA 2 Stage. If you shop you can usually locate the set for $100 and sometimes less. Compare to buying it as a kit form before you decide.
    Sorry, I have used them since 2002 and really like them. I do have a JP trigger in my Sabre 6.5 Grendel Comp Varmint Rifle with K&S Anti Roll Pins. Nice set up also.
    Good luck on whatever selection you decide upon. You always have our support here on the FTF!

    LOL wishful thinking...:p You'll be planning your next build before the barrel cools down from your first range trip...you got the fever now.
