gas block is definitely lines up with the barrel hole and same with the gas tube to the gas block. CHecked the gas key and that sucker hasn't budged one bit and its staked. not sure if a leak is possible but it just being under gassed somehow. BTW using my logic, I ruled out a barrel to upper chamber alignment issue since there are times where the next round isn't even cycled and i get a dry fire. Could this be the culprit as well?

hmmm but with the comp its 16" not sure if that matters or not. I did try my stock buffer which is lighter than the spikes and same thing happened.

it was shooting fine when i had my stock mp15 upper on there would a new upper and barrel change the way it should cycle?

yep I checked the alignment and the paper clip goes into the holes just fine. I'm using stock mp15 spring with spikes s2-t2 buffer. The barrel and biffer are carbine length

I have the spikes s2-t2 buffer but changed to the stock lighter buffer with same results. No reloads, I was shooting PMC 5.56 55gr and since I haven't cleaned the bolt since the last time I shot about 3 weeks ago I would say the bolt most likely wasn't properly lubed and the upper and barrel are brand new. I did take a swab soaked with lube and wet the chamber and the barrel but not a whole lot. But would a dry BCG or upper cause this?

yankee hill low profile. its not adjustable. I was using PMC 5.56 55gr. I'm guessing that the gun is somehow having a gas issue or its cycling too slow for some other reason. I did notice some brass color markings on my brass deflector. not sure if thats normal or not.

Went to the range today with a built upper that has never been shot. Equipment is a rainier upper, sig mp400 14.5" barrel, stock mp15 BCG, and a lower profile gas block. When I was able to get a shot off the brass ejected fine (or enough to not get stuck in the chamber) but after one or two shots it would fail to chamber the next round After I chamber the round manually it will shoot that round fine but then the bolt would go half way and not chamber the next round fully. I suspected a gas issue so I took the gas tube off and checked to see if it was crimped in anyway which it was not. Then checked the alignment of the gas block via the paper clip method and it clears into the hole in the barrel. I haven't tried compressed air into the gas tube yet but it seems to clear the other side when I blow into it by mouth. I can't seem to figure this out. My BCG worked with my old upper and I haven't touched it since I shot it last. Could something have gone wrong with the BCG not cleaning it the last time I shot? I hope its not that fragile. I did the stand the bcg on the bolt thing and it stayed up.

i had the gen ii and loved it, just sold it monday and ordered the gen III. Love the multi reticles but not a big fan of the auto brightness sensor. if you live around central nj you can check mine out if you want.

Going this sunday with a buddy if anyone wanted to meet up...

bumping for more options... i'd be up for a group thing...

i'm down for whenever.

i'm not far from jackson... what day next week? I'll shoot you a PM

yep i agree. That's actually a good idea and wish it came a couple of days sooner. I just sold my upper with the barrel

been to several trips to the range now and again, me being me decided to change her again. Just ordered a new rainer upper, mp400 barrel, and diamondhead back up sights. Guess can't really call it a sport anymore lol

me and a buddy just joined. we live about 40mins from there which is prob halfway from you. i don't know if its worth car pooling but we typically go once or twice a month either on a sat or sun early about 830. it'd be cool to meet some members here.

just curious, whats the benefit of converting to 300 blackout in the real world? i'm a newb so hope this isn't a stupid question.

anyone know someone good that can pin and weld a comp on?

just ordered the DH front and rear sights. how do you like yours ?

yeah? from what i've been hearing I needed to at least spot weld the comp and have it be visible. Sucks living in this state

gotcha, thats a great price... i was just going to blind pin it and have them drop weld the pin hole. i'll shoot them a call to see if they can do it on the spot hopefully.

not too far, maybe about 35mins. What he charge you? And was he able to do it same day?

Anyone know a good shop that can do this on the spot in CNJ? Seems a lot of shops I've called treated this like the black plague and wanted nothing to do with it. One even tried to lecture me on how I shouldn't even be doing this in NJ, blah blah blah.

think this is legal? nothing mentioning a flash hider. 556 tactical stryker

here it is: http://www.ar15.com/archive/topic.html?b=8&f=50&t=457591

i recall reading somewhere that this was NJ legal... In fact I even remember seeing a pic with that comp on there in a thread labeled pic of NJ legal rifles or something like that. Got to search for it now lol
