Hi and welcome. Hit the Introductions section. The first thing about 308 ARs you will soon learn is that there is no mil-spec, and only Armalite makes an AR10. There can be big differences between an AR10 and most 308 ARs. To answer your general question, yes, any buffer tube can work with a psa lower, PROVIDED compatible parts are used inside the tube you get. Thats the kicker. If you are interested in getting all the right parts from one place this is it. https://www.armalite.com/SACItem.aspx?Item=AR10REKIT01&ReturnURL=/Armalite/Product-Category/AR10-Parts-Accessories/Lower-Receiver-Parts&Category=ac614400-ff09-4cdf-9d35-419a654e7201 Yes they are Armalite parts, and they will work with what you have. It shows as out of stock on the webpage but give them a call, talk to a real person and they usually can put a kit together for you.

Hmmmm. Another good question. I was wondering how a 5.56 jig would work on a 308 lower. Are finishing jig kits that universal?

@DNP This is his last sentence... "Here is my 5.56. I can take a picture of the lower when I get home." The pictures are of a 5.56. We still have to wait for the pics of the 308.

....and pictures! Pictures of the lower are good. Show us specifically what you have and what we're talking about.

Softpoint hunting bullets will deform going up the feedramps of an AR. For me it made no difference with the ranges we get shots on deer. For the best consistent accuracy stick with OTM or plastic tipped bullets for at the range.

The guntec barrel nuts I'm familiar with have multiple holes and a torque range that can be used. You should be able to get a set of holes to line up with the holes in the handguards simply by retorquing the barrel nut without shims.

Or touch off a burst that startles the camel and it decides to throw off the pesky human on its back.

@sketch I've got 60 clean and shiny 50 BMG cases sitting in a gallon ziploc bag. For whatever the going price on them is they are yours if you want them

Those are called barrel stuffers! Bet you can't shoot more than one without major curse words spewing forth. Or at least you better not shoot more than one.

^^^ This. I still use the Lee clear red funnel I got way back when with my single stage press kit. It works fine for me with everything from 223 up to 375 Socom.

My main reason to go to wet tumbling was to get away from the lead tainted dusty mess. You don't realize how bad it is until you see the water go into the tumbler clear, and come out black. A good lung full or two of that toxic dust every time you tumble cases can build up over time.

With LC brass, 8208 XBR powder, CCI LRP and the 150 Hornady FMJ bullets, I was getting close to MOA accuracy with my handloads.

Wet tumbler with stainless steel pins, Dawn dish soap, and Citric Acid powder(the working ingredient of brass polish) and they come out sparling inside and out. Gotta deprime rifle cases first though. After they are completely done being processed a 30 minute dry vibro tumble in Walnut lizard bedding with a dab of nu-finish car polish and they gleam. Ask @98Z5V, @Sisco how I know.

Give it a dab of flat black paint and carry on. Chances are with it being that close to the upper nothing will be attached there anyway.

Barrel length? Gas system length? (pistol, mid, rifle) Gas tube length? Receiver extension internal depth? Buffer length and weight? Recoil spring relaxed length, number of coils, and wire diameter? Where the gas tube ends in the cam pin cutout? Read this thread and fill in the rest of the info We can't even begin to guess with the little bit of info we have so far.

Another mystery solved! Dun Dun Dun <--mystery movie sound effect

...and its the buffer weight that is the easiest to change when you need more @ss to control the gas

Those look like fang marks from the feed ramp edges.

Yep, in theory. But aim small miss small.

Sorry to be so formal Elmer.

Yeah, but there is this. Quoting the article: The target’s dimensions (120 inches by 92 inches) made it 1.54 MOA wide and 1.18 MOA tall at 4.4 miles. If that rifle is 2 or 3 MOA at that distance, how many misses would that end up being? Plenty of Fudds in the woods every fall happy with "bottom of ice cream bucket" accuracy from their deer rifles.

It looks like you can still get in on some fall fishing before heading south for the winter.

Just for comparison: Picture robbed from my 375 Socom thread. Left to right. 5.56 6.5 Grendel 300 BLK 375 Socom Thats a 55 gr 223 and a 110 gr Varmageddon in the BLK. Granted it isn't a side by side comparison, but you can see the ogive of the BLK isn't to far forward of that same diameter on the 223 case. A good slam forward on a non-crimped case can get you in trouble.

Short little 110 grain bullets like a varmageddon in a non crimped case COULD set back far enough into the case to allow the bolt to close and lock up. That is why I never load 223 and 300 BLK at the same time. 223 goes in FDE mags and BLK goes in black to further prevent confusion.
