| Is it even worth getting the adam's arms piston conversion???? I understand it will make for easier cleaning, but does that alone make it worth it? |

Carbon build up in the receiver maybe? Which is next to meaningless. Quoted:
Hot gases away from interior parts? Redirecting it to other critical components. Quoted:
Less crap that lube attracts? I could be totally off. You need to lube the weapon regardless of method of operation. |

I'm not sure what affect they have on a .223, but my POF P308 certainly runs a lot cleaner than my friend's AR10 or my AR15.
While a reasonably long gas system and clean ammo, along with lube and maintenance will make a direct-gas gun run perfectly well, I feel that for ease of cleaning and to keep heat out of the BCG (especially in high round-count weapons) the piston system can be very helpful because lubrication becomes a less-frequent task. I've also noticed with my friend's AA-equipped guns that there is no degradation in accuracy inside of, say, 400 meters. they are just fine for carbine combat at combat distances. Go direct gas on SPR/DMR rifles. You don't mag-dump them anyway. |

Feel free to post your studies and/or experiments showing that carbon buildup causes serious problems. Or that the heat doesn't go elsewhere in the system. Or that running without lube is a good idea. |

Carbon build up is a non issue under 1k rounds. Even after 1k, the larger chunks of debris will exit the weapon during the firing cycle. Any machine with moving parts requires lube, it's a matter of relieving friction. If there was a good way to make moving parts require little or no lube, automobile engines wouldn't need oil. Parts with tight clearances run better with lube, period. Heat in a piston gun has to go somewhere, re: thermodynamics (not to be confused with Magpul Dynamics, where magpul is dissipated  ) |
| Go back and read my post, I said it keeps heat out of the receiver. I'm not trying to claim it disappears. I'm not a big fan of have crap blown all over FCG. Like I said, a little amount of lube, and it isnt much, I know. Like I said, to each there own. If you don't like it good for you. The 30,000 posts gotta acount for some wisdom ya? |

So how was my post "blatently (sic) ignorant" then? Again, please back up your statements, beyond tossing out little insults and getting huffy. Why don't you tell me which one of the following temperature profiles is the piston/op-rod weapon, and which is the M4 carbine? Then, for fun, identify the other DI rifle. It actually shouldn't be too hard.

How was it ignorant? A newbie asks about the sytem and you gave him a totally biased answear. It's a tech forum. Thats why, and trust me, Im' not getting "puffy" I have owned (or T&E'd) factory piston rifles, piston conversions, and piston uppers. I have put thousands of rounds through those weapons. I have also put tens of thousands of rounds through standard ARs. He asked if a piston conversion was necessary. I gave him a straight answer. Now, a rifle built from the ground up as a piston/op-rod weapon is an actual topic for debate. |

Heat has to go somewhere? No kidding? I didnt know that bc I swore in my post I just said it keeps heat out of the FCG? I never said it disappeared Heat doesn't affect the FCG one bit. You just don't know what you're talking about, buddy. It sure does! I read it on the internet! |

If the FCG saw any amount of decent heat, the lower itself would also be hot. That doesn't happen. If you meant the BCG, that is different. Also, not a significant enough recipient of heat, where it would affect function or longevity in a semi carbine. The beauty of the AR is the light and simple operating system that allows for relatively little barrel deflection. More parts=more weight, and more mass moving during the firing cycle. Pistons have their place in weapons that were designed around them. The AR15 is not one of those.

I never said it disappeared The funny thing is, if you asked him how much heat was kept away from any of those components, he couldn't tell you. He'd probably be shocked to know that the other features of his POF (which are really neat features and are too often ignored) are far more important than the op rod in terms of heat. |

I have both systems , 2 D.I. and 1 piston, my opinion on it. God help me if the internet is my sole source for info. But yes, those gimmice features from pof is what sold me! If you're talking about the heat sink barrel nut, fluted barrel, large handguard etc, they are not gimmicks. |

That was sarcasim, The Rock Creek barrel is mostley what turned me on among other features |
