Had all sorts of problems with my rifle.I followed all the advice 98z5v suggested and now I have a absolutely fully Functional .308Ar. My gunsmith built me a rifle with the wrong buffer,spring and a gas port that wouldn’t run the rifle. Have the gas port drilled!

Yes he paid for the buffer and spring.But he did charge me for drilling the gas port.I purchased and had the gunsmith do it all so I wouldn’t have troubles.I should have just built and bought it myself.Lesson learned.I am glad I didn’t try and drill it he broke a bit in the firs5 barrel he tried to drill.

You guys really know the AR .308 platform.If it wasn’t for you guys my rifle would have never worked.The back story is this,I had a local gunsmith sell and build me .308 AR.(I supplied the lower)When I got the rifle home the bolt would not lock back and I couldn’t hand cycle rounds.Did research here and found out the wrong buffer and sprng were installed.Purchased the right combo of buffer and spring and installed them.Brought the rifle to the range and the rifle now would short cycle and and not stay open on the last round.It never self loaded.I started asking questions about my gas tube and then was advised my gas port was to small.Brought the rifle back to the smith and had him drill out the port to.094.Took it to the range today and she functions perfectly! Thanks guys you are great!

Thanks Guys, I assume this is a rifle gas system?

So I need to drill the barrel?What about the gas block does the orifice in the gas block need to be resized as well?How hard is it to drill a barrel?

I believe it’s rifle gas see picture below.I unscrewed the gas block and the gas port on the barrel is between .062-.078.The gas block is 1 piece and I am not sure how it comes off due to a ring at the end of the barrel.There are no markings on the barrel besides .308 win 1/10 ,

It’s a cobbled together rifle from a local gunsmith using a PSA gen 3 lower.It has 20 inch barrel with a 7 buffer tube.The buffer is a kaw valley 5.6oz 2.5 inch with a JP extra power .308 carbine Spring.The gun will chamber a round from a bolt drop and fire and extract the empty fine.It rarely self loads another round.The bolt seems to just ride over the next round and closes on a empty chamber.If I pull the charging handle I can repeat the process.On the last round the bolt doesn’t stay open unless I pull the charging handle on a empty mag.I know it’s not the mag because I have 3 different brands.Any and all advice is appreciated.

It looks a bit short to me.
