| So I have been searching and trying to find out as much as I can on the AR57 Upper. I have found a lot of good arguments on it but I have been wondering is it worth it? how available is the ammo and is it possible for the ammo to stop being produced and end up with a worthless upper? I have been thinking about this upper and putting it on my RRA Lower but I need to be sure. 50rds seem nice, looks good, and ammo isn't that much more exspensive. |

Quoted:
How would you compare the recoil vs an AR15? Significantly less? I am looking into getting the SBR'd 11" upper. I think it would make an excellent PDW. If recoil, muzzle flip, and noise are significantly lower than an 11" AR, it might be worth it. Recoil is virtually non-existant. The rail around the upper is so heavy (along with the bbl) that muzzle flip is comparable to a 10/22. With a ~5" bbl and a silencer, it would be a fun PDW... BUT, I really don't think of the 5.7 as human stopping except in the case of an auto P90. |

I've played around with them, and if you own other 5.7 weapons, it makes sense in my book. I wouldn't personally buy one if I didn't own existing 5.7 (or multiples).

I shot an FN 57 the other week it has NO recoil, but it throws a basketball sized fireball I wonder what on it keeps the rounds from falling out the lower mag well Think of a stanag mag fully loaded flipped upside down... same concept, they wont fall out until the bolt pushes it into the chamber. |

Me and a friend just found this upper like 20 mins ago. How is the round only good in full auto applications? We were actually thinking of using this upper as a mainstay over our other options. 8 magazines and 50 rounds a piece looks good to me. Start a thread asking about the 5.7 compared to 5.56 that should tell you enough. PS90, AR57, and FiveseveN's are "cool" guns yet they are not practical. I hate to say it, but 5.7 is the big brother to the .22 mag... Secret Service uses P90's, I don't think they would pull the trigger with a P90 on anything but full auto as I have seen small varmints need a second rd to be humane. |

Pretty sure the secret service chose the p90's because they are low recoil, high capacity, and will penetrate most concealable body armor without overpenetrating the people they shoot. This is not to say its an excellent man stopper for average joe public, since as noted they're using full auto p90's and their main goal is to get rounds on target as fast as possible while missing bystanders. Pretty sure a civilian p90 will weigh less due than an ar57 due to the polymer as well.
As far as 5.7 ar's go I think I saw someone here who built their own which used 5-7 pistol magazines. Not sure if anyone produces one for sale, but it was pretty neat and I think I'd rather have one of thsoe than the ar57 style, because you could do away with all of the heavy railing out front and use a short barrel and simple free float tube. With the +10 extentions you will at least get 30 rounds. |

I would not recommend it as a "main rifle". 5.56 is a much better carbine / rifle round. I'm looking at this as a short range PDW type build for my SO. Quoted:

I have no use for all the rails, and I would like to keep the weight down as much as possible. Stickman: You wouldn't happen to know the weight of the 11" SBR with a loaded mag, would you? |
| Well I went and picked one up! Me and my buddy did some comparison tests my 5.7 vs his .223/5.56 and I must say everything comes out about half on the 5.7....bullet size, recoil, velocity, and hitting force but it's a pretty fun rifle. I wouldn't pick it over the .223 but 50rds if I had to firing as fast as I can pull the trigger I am sure it would get the job done. I was thinking about a short barrel myself but I did notice the 5.7 upper is quite a bit heavier than the .223 |

And compare to other tragedies that didn't use the 5.7? Preliminary research indicates casualties from the incident referenced above are comparable to other mass shootings. Statistics show one to two times the amount wounded as to those killed in most incidents. Statistics did not reveal superiority of rifle lethality over handgun lethality, or vice versa. About the only consistency was the killed to injured ratio. A few examples: 67 rounds fired from Ohio National Guard M1’s in 13 seconds kill 4 and wound 9. Kent State. 13 killed, 26 wounded by gunman using 9mm and .45 caliber handguns. Binghamton, NY. 32 killed, 25 wounded by gunman using Glock 19 and Walther P22. VA Tech. Walt Whitman kills 14 and wounds 32. M1, Rem 700 6mm, .35 cal rifle, shotgun, .357 Magnum, German 9mm were used. * I understand the human element involved in these tragedies. I can’t even imagine how difficult it would have been to lose a loved one in these senseless murders. I am researching the data for statistical purposes. I certainly understand the “statistics” have names and families. |

With the +10 extentions you will at least get 30 rounds. I'm the one that built the other version. It's gas operated (DI) and uses the the AR-15 bolt and carrier system although modified. The picture below is the rifle with 18" SS barrel and 30 round magazine (magazine extension) and can be setup with any type of AR ad-ons. 
A company wanted to make the rifle but I guess it fell through. They had built both a rifle length version and a very short pistol version. I originally built the rifle because I thought the round would make a nice varmint round, similar to a 22 Hornet, but I wanted to be able to use standard AR parts and a scope. I also reload and since this rifle uses the AR bolt system I could load to higher pressures and build my own ammo. The rifle is a really nice varmint rifle but since I didn't build it with the idea of being a lead hose I guess it didn't go over very well. Edit to add; I contacted the company and they are still working on the project and have made good headway. I forget that it's easy to make a one-of-a-kind but it takes like forever to get a product into production. |

I am really interested in a DI 5.7mm with the pistol mag setup. |

I am really interested in a DI 5.7mm with the pistol mag setup. They have two working models, a rifle length and the pistol version I mentioned before so they have all the dimensions. The special bolt and carrier along with the drop-in magblock are about to go into production. Sorry to say I didn't ask about a time frame but I would think around the end of the year. I don't really know what it takes to put something into production and the original AR-57 seemed to take years to finally come out because it took that long to line up people to make parts and dealers to sell them. I think this will move a lot faster since the manufacturer already has other products on the market. |

no question that it is lethal, eventually. But is it good at stopping someone who is trying to kill you before they succeed?
It is a very special purpose weapon & is no good for CQB unless it is full auto. A PS90 might be better than nothing for some extra petite woman living in an apartment complex. If you have the $$$ for fun then get it. Not other justification is needed. BTW, keltech is releasing sort of an uptodate version of the 22mag grendle pistol w/ flush fitting 30 rd mags. |

Buy one you'll love it.....as for all the nonesense that its an over matched 22 mag.. I have seen bears,elk,deer,coyotes and steer all killed with 22mag. its where you put a bullet that counts and with 50 in the Mag you got a pretty darn good chance of being able to put one on target. My rfile shoots great < 1 MOA I hunt an area where most deer are shot at < 100yds I think I'll kill my Blacktail with this rifle in 2011

I bought mine as a novelty. That is what this upper is all about, novelty.
AR57 has low recoil. Actually the recoil is kind of weird because the bolt bounces slightly when a round is pushed into battery. Never install the bolt upside down, it is easy to do. There is an arrow on the back of the bolt that points up. Pay attention or you will have to remove your buffer tube to fix the problem. At the end of the day, this upper is kind of cool. However when I go shooting I grab my m4gery chambered in 5.45x39. I can shoot over 1000 rounds for $129. Trigger time and practice are more important to me than novelty. |
