For a 308 AR not really. Full length resize all the brass you intend on using in it, a case gauge is an invaluable tool to make sure they will chamber. Trim them to spec if necessary. Load them up and crimp with a Lee factory crimp die. Wilson 308 case gauge:

@98Z5V is definitely the man to ask about LC consistency over production years. He has lots of LC 308 cases from some mysterious northern source.

They make the gas port small so they can try to cheat and make the recoil system buffer lighter than its supposed to be. Cost saving measures that cause rifles not to function and customers to come here to get said rifles fixed and working.

98 gave you the gas port size a while back. The man is the Guru of gas port sizes for barrel lengths.

Any good hardware store will have numbered drill bits that will do the job. A #42 or more likely a #41

@SgtDog0311 Glad to see you made it back over here. Where the advice is good, the threads get hijacked, and people call each other fukker out of love! Just watch out for the pants down hugs.

Here ya go. 5 round ASC and in stock to boot. https://gunmagwarehouse.com/asc-ar-10-308-7-62x51-5-round-stainless-steel-magazine.html

@MtnMike Yup, what you have there is what I get also.

Nobody is freaking out my man. My OCD for complete clarity to prevent misunderstanding kicked in when I noticed Lead Pipe had parts installed on his lower and people were recommending pieces he didn't really need. A complete lower parts kit would certainly fix him up and then he would have spare parts that eventually can cell divide and become another complete rifle. We know that happens! 👍

Granted, he does also need the springs and detents for the pin and safety, but they should be fairly easy to come by.

Ummmm, guys. Unless I'm really missing something here, take a close look at the pictures Lead Pipe posted of his lower. It has the bolt catch and mag release already installed, along with the pivot pin! It ain't a striiped lower! He doesn't need a full lower parts kit unless he truly wants to go that route. He needs a trigger, a safety, and a hinge pin, along with the complete buffer system, stock, and grip. Done! Just sayin' unless I'm missing something.

As hunting rounds sighted in at 100 yards they were always MOA in my handloads. But yes the soft points get gashed when chambering. 100 yards or less ranges it makes no difference. I still use the 129 grain SP as the hunting load in my 18" Grendel.

I don't see why not. Lapping is taking the coating off the front of the receiver to make sure you have a square face for the barrel to sit against. Ceracoat and Anodize are both coatings. They will both come off with valve grinding compound and a lapping tool.

Does your range only go out to 50 yards? If so your stuck with it. If not why limit yourself to guessing at every range except 50. If your dead nuts at 100 you can then check at 50 and know both. If your range goes past 100 you can check those and know all of them. For warm weather I'm sighted at 100 for everything except my 300 Blackouts. Those are at 50 but I know they are also dead on at 100 with that 50 yard sight in. The best you can do is shoot and find out what works best for you.

You were the one I was thinking of when I said most of us.

Maybe so. But you are our resident NY expert. Most of the rest of us are just glad we live in free states.😄

First things to do is get an accurate measurement of the INSIDE of the buffer tube, get the quarters OUT of the buffer tube, and measure the diameter of the gas port in the barrel. Using the base of drill bits will get you close. What one fits, what doesn't. Or pull out the caliper.

^^^ This right here! Put this kit in it and be done! https://www.armalite.com/SACItem.aspx?Item=AR10REKIT02&ReturnURL=/Armalite/Product-Category/AR10-Parts-Accessories&Category=4eeff98b-d9a6-40fd-be6b-ab2e44ec1080

^^^ This.

With 308 ARs even the best manufacturers....not so much. Armalite is the original, everyone else does whatever they please with it. There is no Mil-Spec in the 308.

ANY 308 AR needs a 5.3-5.4 oz buffer. DO NOT put a 3.8 oz buffer in it, you are more than likely asking for issues later on. Get this: https://www.armalite.com/SACItem.aspx?Item=AR10REKIT01&ReturnURL=/Armalite/Product-Category/AR10-Parts-Accessories/Lower-Receiver-Parts&Category=ac614400-ff09-4cdf-9d35-419a654e7201 It comes from Armalite and they make it correct every time, but right now shows as out of stock. Find their phone # on their website and call them and talk to a real person. They can usually hook you up with those parts no matter what the stock level says on the site.

Seeing that lead is metal I would think it would conduct electricity at least somewhat. Not as well as gold or copper but some.

So you're saying its trying to feed the next live round into the chamber before the spent casing has been pulled out and ejected?

If you want 30 caliber subsonic to cycle an AR action then 300 BLK is the way to go. The bcg slamming back and forth is louder to the ear than the muzzle blast.
