Sounds like the gas block isn't lined up properly with the gas port on the rifle. Who installed the rail and gas block?
Also, it's called a magazine, not a clip. |

How did it cycle before the change?
Are you using low power Tula ammo? Is it lubed well? If the gas block is not the issue, shitty ammo and no lube will cause a short stroke. Good mags? Did you try another mag? |

What gas block are you using? I ask because the rail you chose shouldn't be used in a real firearm. It's cheap airsoft crap.

I'm not trying to sound like a dick, but these are the kinds of problems that happen when you buy REALLY cheap parts. I know from experience.
I'm guessing that it's a combination of the parts and you being new to the AR15 platform. I can't help but think that the gas block is rotating and coming loose after a few rounds have been fired thru it. |

What turbineguy said. Your gas port on barrel/gas port on gas block arent aligned properly. Start by eyeballing the block at the dead on 12 oclock position, and force it all the way rearward to the shoulder of the barrel, if that is where it is now, it needs to be moved forward while keeping that 12 oclock position

OP, how did you secure your gas block? Since it cycled the first few rounds before turning into a single-shot, it sounds like the gas block shifted while firing. Did you use any thread-locker on the screws or gas block to keep it in place after torqueing it down?

Did you use any thread-locker on the screws or gas block to keep it in place after torqueing it down? This times a million. If for some reason there is some play in the rail with it being cheap, I could foresee it possibly deflecting enough to move the gas block out of position, but your problems are most likely not because of the rail. Use some loctite or rocksett on the gas block set screws to make sure the screws don't back out, or even better, send off the barrel to have it dimpled for the set screw. Make sure the gas block is lined up at the 12 o'clock position and remember with the FSB on there was a handguard end cap spacing the FSB away from the gas block shoulder. If you've got the gas block pushed all the way up against the seat, you're cutting off gas flow. |

If your needs include a rifle that no longer works, then I guess your needs have been met. When I searched "low profile gas block" on Amazon, I don't think anything above $20 showed up on the first page of results. There are times when it is okay to go the cheap route. Buying parts that a rifle needs to properly function isn't one of those times. The best option is to cut down the front sight base that came with the rifle and use that instead of a low profile one. |

I would put the FSB back on and get a used knights rail from the EE...,,you can find them for $80. That way you Will have a rail, like you want, and the gun will function.

OP, the gas block is off. If the rifle worked fine before the rail and gas block then the new low profile gas block is not aligned properly. Most low pro gas blocks account for some degree of variance. Who installed the gas block and what is the manufacturer? |

HERE This gas block is awesome, used (3) set screws, I've had one for (5) years and it has never moved or caused a malfunction... If you like your rail then keep it. |

http://i33.photobucket.com/albums/d90/rusticarts/gasblock.jpg By the way, there was no hole in the gas tube in this failure. Difference in expansion rates allowed gas to escape and it found a weak point in the aluminum GB ( or that's the theory ) here's another one from the forum: http://www.ar15.com/forums/t_6_51/373618_Help___Hole_in_Gas_Block.html I have never seen that happen before.

Cheap gas blocks that fit tight usually work fine........at least for a while. I buy steel gas blocks in despite the fact that I know highly regarded custom gun builders that use aluminum. You removed the front hand guard shim before installing the gas block? Did you measure the distance to the gas port and compare it with the distance inside the gas block to make sure they align? Was the gas block installed as straight as possible. Did you buy a float tube that clamp mounts to the original barrel nut or did you have to remove the old barrel nut and install a new proprietary barrel nut? Is the gas tube aligned in the upper receiver and through the barrel nut without binding anywhere? Was the barrel nut torqued to a minimum of 35 foot pounds of force? Somewhere in this process you created a problem that didn't exist before. Careful inspection should get you to the solution of this problem. |

I completely agree. Ports are guaranteed to line up and itll still be a pinned block. 60 dollar quad rails are top of the line and everything you say should be considered suspect
