well we all know the guy on youtube (jdeluisa) having all the jamming issues. i myself am starting to experience the same issue only after 1000 rounds. i was just doing some failure drill today to get some rounds down range and had this issue. i only shot 150 rounds and i did let it cool off. but when i kinda run it "hot" it started jammin. but when i just sit on the bench shootin casually i didnt have issues. i know bm changed the design of the gas regulator which is prolly the problem. well not really a problem just a way for the freedom corp to sell a few thousand gas regulators to make money. im guessing they changed this and didnt test it. theres no way they didnt "find this issue in testing" cause in less than 2 mags of doin drills it started jammin bad. unless they fired one shot and called it good. and when this thing jams it jams! double feed every time. even with a simple stove pipe. it still starts to feed a round so if you tap and rack it double feeds. not only that the casing usually sticks in the chamber so you have to physically pull it out. yall should do some drills with your acr and see what happens. i dont know about everyone else but we have piss pounded our m16s and they operate just fine.

what kind of ammo are you running? if its steel cased ammo i could see the laquer getting heated and sticking up in the chamber, making it tough to get a round out, it not wolf then i'd probably send it back to bm and see what they say...

mine's done great with whatever i put through it, but i might have got a lucky gun

i'm glad to hear you are issued m16's because the new panzified army is issued m4's (even in basic...) lol

nope american eagle 5.56. its got to be that gas regulator cause i got it a little hotter than i usually do and it started doin it. so i let it cool and heated it up again and it started doin it again. panzified is right. they get m4s in boot! my god! i heard they started letting people qual with acogs and stuff. is that true?

What condition is you regulator in? Does it look like it caked up with carbon?

Only reason I ask is at 1k rounds, I soaked my regulator in kerosene and was amazed at how much crude came out of it.

I haven't had any issues either at almost 2k rounds total. There are times I will shoot almost 300 rounds in 1 hour, (barrel is real hot) and only thing I notice is an occasional fail to lock back on older 20rnd metal mags when using .223 ammo. Luckly I have not had any cycling issues at all at this point.

my weapons r cleaned every time i come back from the range reguardless of how many rounds i shoot. especially when its new. i have been soaking it in solvent so that shouldnt be the issue.

In that case I would concur with bigdog, give BFI a call. Might be something thats outta spec and expanding with the heat causing some binding.

my old roommate had a brand new m4 with aimpoint, the acogs are getting implimented now... fail, what good is a rifle if your optic goes down not to mention how do you hit a 200+ meter target with irons

i'm not sure about the 5.56 problem, it might need the h/l regulator, mine has ate mostly .223, the 5.56 i shot had no problems

nothing should be comming outta spec like that due to heat. if it is then there doing something wrong on their end. i think there comming out with a H/L regulator. i bet thats the issue

have you tied cleaning the gas regulator really well (and I really don't know how you could, maybe buy soaking it in cab cleaner or something) it just doesn't make any sense. how you wouldn't have any problems shooting 5.56 and then all of the sudden you do. It has to be the pin hole in the GR getting plugged. I can see how a new GR for high pressure ammo could solve the problem ...but until when another 1000 rounds and then what another bigger opening in the GR!? I'm just throwing it out there. Bizarre!

again yes my weapons are cleaned everytime from comming back from the range. it usually take me most of the day to clean anything cause i let parts soak. not only have it worried about the hole clogging up ive used the little fuzzy pipe cleaners to help clean and make sure there clear. it should still beable to go 1000 without issues like that. its still picking up the next round so its not short strokeing. do you have a mic to see if you can check the size of the hole? i measured mine to see if it was getting bigger or anything and its not. im curious to see if the gas holes are a tad bigger or the same.

Well, that's interesting info Matt2636, so if the GR is not getting clogged then what else could it be. And yes, we should all be able to firing 10's of thousands until the barrel is no good without a problem... you don't get that with AR's ...right! That's why I like variable setting on other GP rifles, for instance on the XCR and others like it.

I dont think it is the same problem as the guy on youtube, because he has done dumb things to his piston. It seems to me like every gun that has been labeled, "Reliable," he finds some way to make it look unreliable, but I hope you find whats wrong with your gun. Tough Luck =/

You shouldn't even be issued an optic unless you qual irons first.

As for the jamming issue, is anyone else having this issue? Running it hard I mean? I wonder if MAC can give it a good run and try and replicate this problem.

With 3000 rounds fired, using a mix of 223 and 5.56. I have had 2 stove pipes. I have run it pretty hard few times, shooting 300 rounds in 1.5 hours. (for a semi auto that is)

Hey Matt it's great to hear that your regulator problem is resolved.

Now from what I understand this the same method that Bushmaster used to resolve the problem for the guy on youtube. So now that there is a U/S & H/L regulator system, is on superior to the other? and for the H/L regulator, would you just run in on L for supressed?

Setting L and U are the same, no gas escapes. (overgassed for supressor use)

Each regulator has a different function. The H/L regulator is made to shoot unsurpressed. L for .223 and H for very high pressure 5.56. (XM193 for example) The normal U/S regulator; The U is designed for all ammo unsurpressed and the S is designed for surpressed shooting.

What I have observed is the S oriface is .065, the H oriface is .048 (give or take) I have tryed XM193 on the S setting and the rifle will cycle, (bearly) and 20% of the time pick up a new round. (never lock back on last round) .223 on the S setting will not even cycle. I don't have the H/L regulator for testing.

Bottom line, If your going to shoot with a supressor, U/S is the one you need, if not H/L might be the way to go. Personally, I will try to have both on hand. (Just because I like options)

:cool:
