as stated I bought my stock directly from luth. It came with the weird screws. I checked the buffer body with other ones at my local gun shop, they all were the same length of mine. Not to sure what is going on here.

I'm gonna buy complete rifles and kits from them since I'm so satisfied with my purchase. (sarcasm) already talked to my credit card company, they're gonna cancel the charge due to this. They've gotten other complaints.

Okay, can someone link the buffer body I should buy from Luth? The only one I can find for .308 is an A-2

I just called their customer support line. At first it said they're only open from Monday to Friday. But then some lady named Kayla answered. And no my kit did not come with that, that is why I was so confused when the bimbo on the other side said I have an A-2 set up. Like what the fuk. So right now it seems like I need the shorter screw, and a none fucked up buffer body.

Okay now i'm officially confused.. I was able to get in contact with someone from luth (On the weekends, this rocks) and I told them what I had. The gal on the phone said my A2 system needs a longer screw... I have an A1 system, and told her I need a shorter screw. She said that was incorrect. What......

I took a double check of the box. There was no vented screw in it. I bought the stock right from luth themselves. Starting to wonder if maybe I got a returned one. The only thing in the box was the stock, and the instructions on how to install it. No vented screws, just the ones I pictured*

I took the buffer to my local gun shop and by chance they had another complete Luth kit there. The buffers are the same length, and we compared it with multiple different ones. They were all the same length (expect one that was 1/3rd inch longer)

Yah I didn't want to buy from them. Haven't since the entire sandy hook thing. But they were the only ones who could overnight my part to me and I need it for the weekend. The one I ordered from midway ran into a problem and was back ordered for 3 weeks.

This is the kit that I ordered https://www.cheaperthandirt.com/product/luth-ar-ar-308-rifle-buffer-tube-assembly308-win-859819007256.do?from=Search&cx=0 and okay i'll will get the vented screw.

There is only about 30 rounds through it, and it was lubed pretty heavily. I was also shooting Fiocchi 150 GR FMJ .308 and the BCG locks back at the face when I manually do it. Here are the pictures of the screws that came with the stock. (came with two)

Wait, there was suppose to be a spacer? My stock never came with a 5/8 A2 spacer. I'll have to take a look and see where to buy the correct spacer at.

I was able to rule out the screw pretty quickly by installing a shorter one I had. It was not the problem. But I used the CMMG - 308 AR LOWER GUNBUILDER'S LOWER PARTS KIT as seen here: https://www.brownells.com/rifle-parts/receiver-parts/parts-kits/repair-parts-kits/308-ar-lower-gunbuilder-s-lower-parts-kit-prod72275.aspx I've heard good and bad (mainly bad) things about CMMG so purhaps the one they gave me was a AR-15 one and not a a .308 one?

Hey everyone, My bolt is not catching properly, when its an empty magazine. My build is a Aero M5 lower, and 18 inch upper with an aero BCG. . The gun cycles fine, but won't lock back on an empty mag. I can lock it back fine manually with no problems. I took a picture of the measurements of the spring, buffer, and the buffer tube. I read somewhere that it might be the screw that holds on the stock on that sometimes they can effect how far back the buffer can go? Anyone have any ideas? Thank you.
