| I recently received my M6A2 and was wondering what others that have piston rifles do as far as cleaning and maintenance is concerned? How often do you clean it? Also, I have a 30 rd PMAG loaded with 25 rds and it wont lock in the magazine well on a closed bolt. I thought it would? Thanks guys. |

I have the M6A2 and have had only one fail to feed, I just wrote it off to being a new rifle. Has not happened again. There is not a lot to do on it that you would do different from your DI rifles. They run cleaner but still do require routine maintenance, pull out the BCG give it a wipe down hit it with the EWL or some CLP. Run a bore snake down it from time to time. Check the camber, ect ect. As for the piston, separate the rail halves pull the op rod apart and give is a once over. The Manual is your friend. It is a very simple process.

I have a DI rifle as well and seems like I spend 45 min to a an hour cleaning it. I don't have MIL or LE training yet so one of my MIL buddies showed me what to do that's why I'm not as much of an expert on some of the maintenance issues. I was kind of assuming every 200 rds or every other time I take it shooting to run a bore snake and maybe a few patches down the barrel and CLP on the BCG. I thought I wouldn't have to bother with cleaning the lower though?
My first round I attempted to fire was a FTF. I loaded it back into a magazine and it fired just fine...was kind weird with it being the first shot fired. I admit I haven't read the manual as I didn't know if there were things the manual recommended that most people ignored. Having said that, I'm not even sure how often to check/clean the piston itself. Anyone have any ideas about inserting a PMAG on a closed bolt with a LWRC? BTW, thanks SirJames556. |
| No problems here, over 2k thru. Clean bore after every trip to range with bore snake (reusable and washable). Wipe down bolt with CLP. Never noticed anything with pmag in well with bolt closed. Very low maintenence. I check the carrier key every time though cause it's not staked. Was told by LWRC that the metal was too hard to stake. |

I just got an M6A2 5.56, no problem with PMAG or any USGI mags. I just wipe down the BCG and the receivers, boresnake the barrel...done. So far the best part about this weapon is the quick/easy cleaning.
My first impression is not so good though. Got frustrated with the Troy BUIS that came with the wpn. The BUIS will not zero or hold zero (everything checked for tightness); it was all over the target. Taking it out again today with an ACOG to rule out the front rail problem or something else. I don't want to be quick to judge LWRC's product and QC, however, for over $2K spent, LWRC should at least check the zero before shipping it out. They don't even address BUIS zeroing procedure in their Operator's Manual. Functions wise, it was flawless, no problem with PMAG or USGI mags. The GP recoil is a bit violent and snappier as compared to the smoother DI AR with a $10 gas tube. I'm still not sold on Gas Piston AR. I will give it another 500 rounds...but I have a feeling that I'll be going back to my dirty filthy hot smelly DI system. (This is not intended to be a gas piston bashing. It's just one man's opinion.) |
| I got an LWRC M6A1 about a month ago and just zeroed it at 50yds yesterday. I only put 180 rd through it (all Prvi M855/M193), but I did not need to touch the BUIS. It was dead nuts right out of the box! Twice though when I dropped the bolt on a loaded mag (30 rds Pmag& D&H) it wedged the round between the chamber and barrel. Not a big deal and an easy fix. Other than that the rifle was flawless! Stupid easy to clean too! Boresnake and a quick CLP swipe and all was good! |

I clean the gas system when I feel like it... honestly thats it... if I didnt want to clean it for 1000 rounds I would not. Sometimes I clean it after 50 rounds. I can load a PMAG on a closed bolt with 30 rounds easy. You must have a defective mag or something. From your description I think YOU did something like have a bullet hangout out the front or someting similar. Its not the rifle if it will load 30 and loack the bolt back onthe last round at 25... its something you did if that is the case. |

Since January I've put approx. 1500 rounds through my M6A1 upper. In total it has about 4000 rounds through it. Mostly cheap stuff like wolf and silver bear.
The piston has NEVER been cleaned. The chamber is starting to look a little nasty, but there is still plenty of lube and it doesnt feel very gritty to hand cycle either even after a thousand rounds or so since its last cleaning. |

Oh, thank you O'Great One for your input. Of course every idiot knows how to sight a wpn. But when problems do occur, it would be nice to consult the manual, just to make sure it is not the shooter that is at fault. 2. Not asking manufacture to zero, just check/QC when test firing to at least make sure it hits 2x2' target. As it turned out, the M6 was put together on a Friday after Happy Hour (sarcasm). The front rail was not installed properly and the piston wasn't aligned correctly (it worked but hence the off-centered recoil). IMHO, Having the front sight sitting on the freefloat rail on the M6A2 is an engineering flaw. The tip of the rail has no anchor point so it is able, with mininual pressure, shifts / flexes slightly to cause shifts in zero. This problem is corrected on the M6A3, the front sight is attached to the gasblock/barrel...no possible movement from the hand rails. I haven't shot it since correcting the problem. Might take it out today. |

The rail cannot move with any amount of pressure once the set screws bottom out and lock up tight. |
