AR 15 questions

    My opinions are based entirely on what I've heard (I've shot only one brand of AR), but here's what I think: Bushmaster, Armlite, S&W. I've never heard of Stag so I won't rank it. Is it really Armlite, or Armalite? If it's Armlite I might not have heard of that company, either. I've heard S&W isn't really a S&W product and is overpriced, besides.

    The real reason I respond is not because I have good information for you (is that obvious yet?). Rather, I post because I want to know: what is an 'open bolt version of the AR'?

    This "expert" claims he had and open bolt AR and it was the best one made and that I should get one of those. I think he was just full of crap. Open in that it fired from an open bolt.

    There was a blurb in a gun mag just this week that said Stag is the one actually making the S&W rifle, they just don't talk about it.

    Sounds like that guy was FOS. I've not heard of or seen n AR that fires from an open bolt.

    Probably the best and most accurate info of ARs can be found at AR15.com

    [;)]

    Plenty of good info there so you can build your own in the exact configuration you want and save a few $$$

    I know the M60 fires from the "open bolt" position. I haven't thought about the AR15 firing that way..... I need to do some research. My first thought was that if it was fired on Full Auto, it was firing from the open bolt position but I think that's wrong....

    It's wrong, here is the C & P from wikpedia:

    Open bolt
    From Wikipedia, the free encyclopedia
    Jump to: navigation, search
    A semi or fully automatic firearm is said to fire from an open bolt if, when ready to fire, the bolt and working parts are held to the rear. When the trigger is pulled the bolt goes forward, feeding a round from the magazine into the chamber and firing it. Like any other self-loading design without an external power supply, the action is cycled by the energy of the shot; this sends the bolt back to the rear, ejecting the empty cartridge case and preparing for the next shot.

    Compared to a closed bolt design, open bolt weapons generally have fewer moving parts. The firing pin is usually part of the bolt, saving on manufacturing costs. Having an open chamber while not firing also helps keep the weapon cooler. However, accuracy suffers due to movement of heavy parts prior to firing, and lack of full lock up between bolt and barrel.

    Many open bolt weapons are shown, in movies and video games, to erroneously need to be charged after reloading. This is not generally true, however, as the operation of basic open bolt weapons sends the bolt carrier back into a cocked position via the excess gas from the spent round.

    [edit] Notes
    In the U.S., the ATF made a ruling in 1982 that semi-automatic open bolt weapons are readily convertible to fully automatic fire, therefore such weapons manufactured after the date of this ruling are classed and controlled as fully automatic weapons (weapons manufactured prior to the ruling are grandfathered and are still considered semi-automatic).

    I'd get an ATR-1. FAL based platform, takes ar mags, uses many standard FAL parts.

    I'd personally spend a few extra dollars and buy a nice older Colt SP-1.
    It will be sure to go up in value and they are a nice rifle.
    Just my opinion.

    I have two rifles built on Stag receivers and they are every bit as tight as any other AR15 (or M16) for that matter. Stage is an excellent value for the money!

    There is no difference in the quality of the four companies you listed. OH , there is a different logo on the lower receiver. Just pick the logo and name you like best.

    My dad actually built one. It wasn't a simple machining from a lower from a cast and bolt on parts. He machined alot of the parts including the lower for blocks of aluminum. I was going to be a project we were going to do together, but all it did was cause fights with us. So he opt to build just one and by himself. I thought it was neat, but a very ugly gun. He was also afraid to shoot it, scared of his own work So he's since then scaped it.

    It maybe just cometics, but there is a differance. I've notice the lower on the Smith is alot cleaner, better trimed, especially around the pistol grip. The fit on the Smith from lower to upper is also very tight. I think the Bushmaster is the roughest trim out of all the one's I've seen now. Colt what what I've hear is a good one, but there machining is not as good as the Smith, but blow the Bushmaster's triming out of the water. The Smith's trim is very good you can't see any cast lines at all

    22LR, 9mm, 45acp, 40 S&W, 50AE...AR15 uppers do not having locking bolts.


    bolt action upper for the AR:
    www.safetyharborfirearms.com/UltraMag_50/ultramag_50.html

    Why no one has made a 30-06 bolt action upper for the AR15 is besides me. They could make it magazine fed just as the 50bmg upper in the link above with the mag on the left of the upper receiver.

    On a scratch build, I think Stag Arms make the best lower receivers (If there is a "best," they are all milspec) for the money. I just built a pistol on an AR frame---Stag Arms was kind enough to include a certificate of un-assembly so there was no hassle from my FFL to receive the lower as a pistol, and to register it as a pistol on the ATF Form 4473.
    I think the biggest difference-maker is whether the lower assy is forged or milled.

    I thought the same as ObiWan, although I thought that the only open bolt was the 9MM. I'm ignorant - didn't even know those other calibers were available. Shouldn't be much of a project to convert them to full auto, in a country where it's legal.

    email Justin and ask him if he still has some 10% AR45 lowers. They take M3 Grease Gun mags...Oly Arms 45ACP uppers.
