Greetings from Manchester Mi, I purchased a 24" hvy ss barreled upper. I always lap a new bbl. As I looked down the pipe I saw a burr. I mean .004 of .005 around the gas port. And the hole seemed to be BIG. I mean 1/8 inch or more. So out to the shop I go, patch the bbl out,& begin to lap it. OH OH, big resistance on that spot. I sent it back. They send me the same upper back, w/ a note cleaned out burr w/ a cleaning rod. Nope. same "feel" same .200" gas port mistake. They claim the 204 hole is .006 bigger than the 5.56 hole. None of my 8 ARs have a visually big gas port hole or a definite sticky spot while running a cleaning rod down it. School me on this 204 gas port. Thanks, Red

Don't know if the 204R would need a larger gas port hole or not, could be to cycle properly. However I would ask the company to take this upper back and either replace it or the barrel, as you just do not want that burr/bad spot in the barrel. Bill K

I agree, send it back for a refund. Don't think I'd want to shoot a gun with a tight spot in the barrel. I'm not sure if the gas port hole is bigger on my .204 barrel or not but a quick call to Shilen who makes barrels should get you an answer. I used a standard size gas tube and my AR cycles just fine.

The company I bought it from says .089 for 204, ,082 for 223. One could not see that little diff. I see a HUGE looking hole. I sent it back. They get 1 more shot at it. Then I WILL get a Shilen. Probably should have done it in the first place. Doublestar 24" SS hvy bbl from JT dist...................
