Pistons dont get dirty <---------- LOL
Keep in mind the US military rated the M16 DI with one malfunction for every 4000+ rounds fired. The AK has only a slight advantage over the AR in reliability.

That's a little bit of a miss conception on that article. The HK416 was fired with a suppressor. I don't know if you have fired a suppressed weapon but I have and any excess gas trap in the suppressor goes back into the action. I fired a HK MP5SD and the smell from the gas coming back into the receiver was burning my eyes. If you fire a M4 with a suppressor the excess gas and noise escapes though the two gas ports in the carrier. Also it could also be that the PMC and the XM193 that he used was not the ammo recommended by AAC for use with the suppressor.

There was no miss reporting. He stated that his gun was fire suppress. It makes no difference between a DI and piston where the fouling will be located when using a suppressor. It will go back toward the chamber and onto the bolt.
If is unsuppressed, the fouling in a piston rifle will be located in the piston and piston tube. In a DI it will be on the bolt. My experience with suppress M4 is the gas blow through the charging handle into my eye. That is taking care of when you use gas sealant on the charging handle or buy a gas blocker charging handle. It doesn't matter if there is excess fouling as long as it is lubed in an AR15 DI. The US military has tested and rated the M16 with one jam for every 4000+ round fired. |

All weapons foul up their gas system. I am saying from experience that the piston system is more robust then the DI. Also the fouling is not inside the bolt carrier on a piston system as in the DI. |

I don't have the link it was a white paper on the M16 published on carbon paper in the 80's.
If you don't lube your weapon any weapon it won't function. That's a fact. You might get lucky and work without lube like Big Bore stated but would your risk your life on it? No run your weapon wet. All piston AR and rifle that design similar to it has one big problem. Piston binding. The piston jam on the gas tube. Once that happen it's over because there is only one way to clear the malfunction and if that doesn't work you have to do a complete disassemble. Collapsed the stock slam it on the ground as hard and fast as possible and hope the piston unbind itself. Unless it is a oversize gas tube like the AK the risk of piston binding are high. Of course there will be less fouling on the bolt in a piston rifle because the gas is hitting the piston. The fouling will in the piston and gas tube as I pointed out many times. The fouling will be the same but in different location between DI and piston rifles. The fouling does not magically disappear on a piston rifle it just deposit at a different place. HK416 in suppress mode jamming. http://rpginn.com/index.php?option=c...=443&Itemid=39 Last edited by jdun; 06-04-2009 at 07:23 AM. |
