What length is the gas system?
Check seal around gas block Make sure there is nothing stuck in the gas system somewhere |

to me it sounds like you are on the right path.
Could the gas block be slightly misaligned and getting an insufficient gas to cycle? Since you've tried several combinations, if it were just me I'd strip it down, inspect, reassemble gas block. If you've got another gas tube I'd swap it out too since they are relatively cheap. I'm sure better advice will follow. |

Rifle Length system. I'm pretty sure it is aligned, and the seal should be good, but I will check it. All components were new. I will take it apart a re-check everything. Thanks!

Used 3 different complete lowers, one with a JP captured assembly, one with colt h-buffer and standard spring, one with spikes h-buffer and standard spring. I really don't want to have to swap out spring and buffere each time. It appears to me the issue is with the upper.

What stock do you have on it? Are you using the correct buffer and spring? Quote HistoryQuoted:

To get the rifle running you should start with a standard (carbine) buffer and a standard spring...if this is a telestock (carbine) buttstock system, of course. Also, we don't know what ammo you are using. If it's cheap, imported stuff or low pressure .223, that could be part of your problem. Use full power Lake City XM193 or M855 to get the rifle running. If your gas block alignment was good, you should see a carbon trace around the barrel's gas port, upon removal of the gas block. (the port in the block is larger than the port in the barrel) |

It also could be the gas hole or port in your barrel may need to be drilled a little bigger because it may not be letting enough gas through to cycle the bolt properly.

Gas system blockage or alignment.
Gas tube blockage is a low probability, but it does happen. Too much friction in the upper slowing down the BCG. Is the receiver extension lined up with the centerline of the upper? Weak ammo. Measure the gas port and contact Wilson to see if it is correct. Drilling the gas port is a last resort as it cannot be undone. If you do decide to drill at most go to the next decimal sized bit above the bit that fits the hole. |
