| What ever happened to that stupid looking gun? |

WHY IS XM8 NOT VIABLE BUT GLOCK IS. IT SEEMS HAVING A PLASTIC WEAPON DESIGNED THAT CAN BE MOLD INJECTED BY THE MILLIONS FOR DIRT CHEAP IN A GARAGE IS A GOOD IDEA. I THINK THEY SHOULD MAKE A PLASTIC WEAPON AS CHEAP AND SIMPLE TO OPERATE AS THE AK-47 OR EVEN CHEAPER. THE SAME WITH AIRPLANES AND TANKS AND ARTILERY. JUST HAVE A BACKUP PLAN TO MAKE LOTS AND LOTS OF SUPER CHEAP WONDER WEAPONS. SOMETIMES SIMPLE IS BETTER SOLUTION! |
I got to handle a XM8 (but did not get to shoot it  ). Honestly I really liked the way it felt in the hands and think it could have been a good carbine once the bugs were worked out. Honestly though I fail to see how anybody benefits from another 5.56 rifle and that even applies to the Masada/ACR.
|
AND THE SIMPLE SOLUTION IS TO USE WHAT WE ARE USING RIGHT NOW INSTEAD OF F!@#ING AROUND WITH NEW THINGS THAT ALREADY SHOWED THAT IT OFFERS NO ADDITIONAL BENEFIT |

H&K Arrogance Failure. 9-11-01 provided an opening for more tools. H&K saw fit to grease some influential skids, and then worm thier way into a better position than FN. Thier High priced Liars and corrupt Experts FAILED. The XM-8 was and is, a failure as a replacement or improvement over the M-4 and was sniffed out early when a certain Dentist...er "Doctor" that constantly derides the performance of the M-855 out of a 14.5" barrel, all of a sudden was pole swabbling the the XM-8 with an even shorter barrel. Other aspects like "Cost" and other simple matters were a factor. And in the longer run, as soon as the Army started to get off thier dead ass and re-reinforce the issue of Maintenence on individual weapons in support units, the bitching about the M-16/M-4 slowed to a trickle. In short? Battle proven vs. Snake oil bullshit supported by heavily paid "Exspurts" often quoted in a slanted media that were all to ready to bash on our troops armament. Modular is a neat concept. If it works overall. The XM-8 dosn't. the M-4 works OK, for now. Fuck H&K!!!!! S-28 |

For you guys who are not in the tooling industry, the REAL beauty of injection molding is that there are no other finishing processes after the part is pulled out of the mold cavity. An AR15 manufacturer can have an "oops and aww shit" and put a trigger group pin hole off location if he doesn't fixture the reciever properly, picks the part up wrong when setting up for a run of parts, or misses his numbers when programming the CNC. With an injection mold, if they are right when the mold is built, they will always be right. Cheap, accurate and fast to produce. There are some really cool things you can do with plastic that you can't to with a machined forging.... |
Because the Glock does not require its frame act as a heatsink. Notice the FN SCAR and the MASADA use an aluminum upper. This is called a clue. |
HK has now submitted the XM8 as a possible interim replacement for the failed RAH-6 Commanche recon helicopter program. They have several fanboy writers of helicopter magazines writing articles every month about how the current crop of recon helicopters "aren't the best money can buy..." and how the military needs to do better, somehow, wink wink nudge nudge. |
And some of us have actually used the AR platform when it counts and know that its a damn reliable weapon, with accuracy and ergos that blow the AK out of the water. The military shouldn't switch unless its to a bullpup. Nothing else short of some caseless wonder will offer any real improvement. |
ROFL I LIKE TYPING IN CAPS CAUSE IT ENHANCES MY 10 POST COUNT STANDING LULZ |
 There is no shortage of piston driven 5.56 rifles on the world market today with ergos matching the AR. There is just no need for yet another 5.56 rifle on the market. Oh and BTW The AK is nothing more than a reliable piece of shit. Sure it goes bang eveytime, but then hey my crap tends to stink every time I defecate as well.

+1 Find the button that says "Caps Lock" on your keyboard, and "fuck around with it" until the green LED under "Caps Lock" in the upper Right hand corner of your keyboard goes out. |

They wouldn't however the XM-8 was far from "properly" designed, in the Army field tests (and yes they did test this "uber weapon") the test samples MELTED, hence the Army said to HK, "uh, NO, come back when it doesn't melt". The XM-8 had inferior plastic, and it's upper Receiver acted as essentially a Heat Sink, and Plastic doesn't make a very good Heat Sink, and in other news Gasolene sucks at putting out fires, water is wet, and the sky is blue. |
That is like saying the concept of a lead airplane is going to be the future. Ever notice neither the barrel nor the slide on a Glock is plastic? Plastic just can't be a replacement in certain apps. If they can find a plastic you can melt to injection mold but the heat of the barrel won't melt. The all-plastic rifle is a pipe-dream. Physics is a bitch. |
A Glock fires 15 or so rounds at a time, semi auto... The XM8 is full auto, with a VERY high rate of fire... It got VERY hot VERY fast, and that caused structural failure of the polymer reciever... Just like it's 'parent' design, the G-36... It was also inaccurate as hell... |
Sure maybe, but that's after the plastic stops melting. Assuming the XM-8 didn't end up looking like something dreamed up by Salvador Dali what does it offer that the M-4 does not? Would lot benefit if any justify the cost to replace all the existing M-4's, fill the supply system with new spare parts, and retrain all the troops, and armorers on a completely new weapon, then field what is an unproven design? |
To their credit, the XM8 had a steel barrel, bolt and gas system... But what it comes back to, is that what works for semi-auto pistols may not work for full auto rifles.. P.S. They make composite AR/M16 recievers (Bushmaster Carbon-15)... But that's carbon-fiber polymer, not plastic.... |

An open letter to the gun community from HK’s marketing department: In a world of compromises, some people put the bullets in the magazine backwards…But it doesn’t matter, because our gun is on the cover of the Rainbow Six video games. Look how cool that SEAL coming out of the water looks… If you buy a $2,000 SOCOM, you will be that cool of an operator too. And chicks will dig you. At HK, we stuck a piston on an AR15, just like a bunch of other companies have done, dating back to about 1969. However ours is better, because we refuse to sell it to civilians. Because you suck, and we hate you. Our XM8 is the greatest rifle ever developed. It may melt, and it doesn’t fit any accessories known to man, but that is your fault. If you were a real operator, you would love it. Once again, look at Rainbow Six, that G36 sure is cool isn’t it? Yeah, you know you want one.And by the way, check out our new HK45. We decided that humans don’t need to release the magazine with their thumbs. If you were a really manly teutonic operator, you would be able to reach the controls. Plus we’ve fired 100,000,000 rounds through one with zero malfunctions, and that was while it was buried in a lake of molten lava, on the moon. If you don’t believe us, it is because you aren’t a real operator. By the way, our cheap, mass-produced, stamped sheet metal guns like the G3 and MP5 are the bestest things ever, and totally worth asinine scalpers prices, but note that cheap, mass-produced, stamped sheet metal guns from other countries are commie garbage. Not that it matters, because you’re civilians, so we won’t sell them to you anyway. Because you suck, and we hate you, but we know you’ll be back. We can beat you down like a trailer park wife, but you’ll come back, you always do. Buy our stuff. Sincerely HK Marketing DepartmentHK. Because you suck. And we hate you. |
It is the ability to barf out rifles by the millions on a machine you can dump a barrel of plastic beads on one end and have most of a rifle come out the other! |
I don't know if you work in the CNC/manufacturing world, but when an NC program is made and part is machined, the completed part should be inspected to ensure NC program and machine set up is correct, this is true for every run of parts. If a mold is made, the part should then be inspected for every run of parts as well. No different than the NC world, only difference would be with a mold, you may be able to able to manufacture the parts faster since a injection molding may require less steps. The thing to remember is, injection molding will still have to go to a mill for features several features such as trigger of hammer pins. It really is no different than building a receiver from a casting. |
Too bad the rifles it would barf out would be useless as a functional weapon. Again, physics is a bitch. Barf is an apt description though because that is what you would get. Some things plastic is good for, others not so good. If you can find a way to make the second law of thermodynamics not apply to a rifle upper reciever, then mabey your wet dream will become a reality. Mabey GM will make a plastic engine too. Untill then, really hot steel will melt anyting polymer like you can injection mold. |
Which does you no good if they melt. |
Nice!

This kid has to be one of those Airsoft guys we were laughing at.... only explination |
I agree, but the you gotta admit the Masada is pretty freakin sweet

CAPS LOCK! UNLEASH THE FUCKING FURY...................... BEEEEEEYOTCHES |

As an aside, directly related to the XM-8 rejection, and the rejection of negative hype... Anyone else notice that "Piston operated uppers", "New Technology uber lubricants", and more complicated hardware keeps getting foisted as the "Answer" to the age old challenge of maintaining discipline and drill amoung warriors? Like our Military could grab 2,000 random Wal-mart shoppers and put them in uniform, and like Vince at Sham-wow "BAM!" Detachment Echo and Foxtrot are the new elite Uber troopies. Our best have discipline, and have perfected the practices of the old rules and traditions. No extra moving parts, ultra secret lubrication formulations, or Space age gerbil pruners need apply. The XM-8 was marketing hype. H&K is a bullshit foisting bunch of inbred profiteers. They failed. So did all of those that sold thier soul, and previously decent name to ride along. Veteran or not. Officer or not. Doctor or not. Just 3 days ago I tried to order parts for our USP's. It was like trying to get a scrump buddy hook up, and having her Husband approve it in person. Fuck H&K!!! S-28 |
