Can I use a AR-15 gas tube or must I get an AR-10 tube from Aero only?

So it seemed that the site was offline for a while and now it is back.

Any way to get the word out?

Well, I finally got mine back. The intent was to cut and thread the 10T barrel for a suppressor. After 20 years, the hand guard wouldn't come of, so it was destroyed. So, Armalite 15 inch rails, Oden low pro and adjustable gas block, QD Suppressor flash, and other appropriate gun smith work; a SASS conversion for less than $600.00. MSRP for a SASS upper, $1841.00. Guess I can live with that.

I noticed the post were old, and was surprised. It's not as if the AR 10 is a dying breed. However, I'm also a 300 Blk fan and that, along with the 6.5 Creed is the new gun nut rage.

Fully intend to enjoy the conversion, esp. when the CAN comes in.

Site showed your post count as 1 so I figured you were new here, nobody has posted much for a good long while here. Still a ton of good info to be had though. Enjoy the new configuration!

Thanks for the welcome!! Have not posted to the site in a long time. I've been shooting .223 for years and my 10T has been gathering dust. Started shooting my Rem. 40X and decided to get back on the 308 train. Hence, the idea of the SASS configuration.

Hey Bro,
Up from you in FLL. Have owned my 10T for 20 years, I think. Back when they came with 24 inch CM barrels. Decided to modify it into a SASS configuration. Cut & Crown barrel to 20 inches, thread for a CAN, and put new Armaltie Rails, and low profile adjustable gas block on it. Maybe he'll get it done by the time ATF approves my CAN.

Gunsmith is catching the devil trying to get the barrel nut off to turn the barrel. That seems to be an issue for 10T barrels, as I researched the process and others have had great difficulty getting the barrel off.

Don't know where you shoot in Mia, but Markham Park here in Broward.
Another welcome from Iowa!

Just got my first semi auto on 308. Looking to learn as much as possible from the more experience shooters on the forum, both in overall gas gun techniques and reloading for them.
Being shooting my bolt gun for a while now and got interested in trying a new weapon.

Welcome! That smear is perfectly normal for these rifles.

There is no standard for the large frame AR's. Get your stuff from reputable sources, JP and Fulton Armory are a couple of the best. Armalite is top notch but then if you are running a LR308 then that might not be an option, best to keep everything from one maker.

Perfectly normal. With an adjustable gas block or a heavier buffer you can lessen it some but the further you take it the more chances of having issues with function.

I have a current build of a AR 10/DPMS .308 Win. I created this with a left hand side charger from Gibbs Arms and mated it up to a SunDevil lower. I have been getting what appears to be ejector smear and it happens on new and reloads. I am using an Anderson Arms Bolt Carrier (AM-10 Bolt Carrier Group, Nitrided – .308) and I have an extra bolt made by JP Enterprises which is their Enhanced Bolt Chromium Nitride. While examining both bolts to try and figure out what was going on I discovered that both of the bolts had the same issue I believe, which is a sharp edge on the ejector pin hole. I took it upon myself to polish the edge with some Simichrome and rouge, just enough to remove the sharp edge which was digging into the brass and scrapping up a little pile when the bolt rotated. I've not had a chance to fire the modified bolt yet to see if it eliminated this problem. However I am looking for comments to see if anyone else has had this happen.

I am looking to see if there is a standard dimension for the bolt of the AR 10/DPMS .308 Win. I believe that the 2 pins that I have are quite sloppy. One is .004 under size and the other is .007 under size. I've contacted both manufactures of the bolts and both claim that there is not a real standard on the bolts for dimensions. The two bolts that I have both have the same bore dimension for the Cam Pin (.3755) and I have two different cam pins with different dimensions, .3715 and .3685 giving me a clearance of .004 and .007 for the pins. I did get a fit clearance from the JP Enterprises of .0015 to .0035.. The reason for my concern is this cam pin is special for the side charger unit and their target is .3685 - .3695 and their pin is in spec. When I challenged the tech he again claimed that they are in spec and said that there are no real standards on bolt dimensions.... I explained my concerns that the pin is chucking in the bolt and leaving marks on the pin that you can detect visually and with your finger nail. I realize I can get the pin coated but I would really Like to get the drawings to further my understanding and what I need to do.
