I'm looking at some drawings. Are folks here milling with a milling machine or doing it some other way?

Duh, brain fart. After replying it all came into focus. I was picturing the fire control pocket in reference to the detent pin hole. Instead its the 3 holes in the side measured off the detent hole.

How do you indicate to find the detent hole location. I imagine using a rod in the detent hole to indicate against, but how do you set it up when you set the receiver upright?

Would there be a noticeable difference in weight between barrels in a completed build, all other parts being the same?

The Collapsible stock I had on my 16" AR15 was not comfortable with a scope. I assume the magpul fixed stock would be better in that regard. Being comfortable using a scope is one of the main criteria for this build.

I am building a DPMS pattern rifle. It will be a 16" mid-length gassed barrel. From experience with scoped AR15's, a collapsible stock will be a bit too short to be comfortable. But an A2 length seems too long. I'm fine with and actually prefer a fixed stock. What options are there for something in the middle? If it matters, this rifle will suppressed most of the time.

Just curious, what kind of build did you use it in?

They must have just changed the price. Yesterday, that BA barrel was $127. Should have bought without worrying I guess.

I thought it was listed at 35 Oz

I'm looking a building a hunting rifle, 16" and suppressing it. To that end, I want to be lightweight, although I'm not tryiung to build the lightest possible. I just don't want it to be 'too heavy'. By comparison, I have a semi-heavy barreled 16" AR15 I use for predators and I would love to be able to have a 308 that didn't weigh more than that. I'm looking at the Ballistic Advantage 16" tactical government profile in .308 mid-length. I was wondering if anyone had experience with that barrel, and if so how the build came out weight wise.

I currently have an 80% 308 lower, which I plan to mill out to DPMS specs this weekend. My intention is to build a 16" hunting rig, fixed stock, semi-lightweight and suppress it. I am getting ready to buy parts for the build, am I correct that: any upper receiver will work Barrel and bolt have to match (DPMS/DPMS or AR10/AR10) and carrier is non specific hammer/trigger/disconnector can be 'any' 308 labeled set, and the rest of the lower parts need to be either DPMS or AR10 specific any buffer tube matched to a stock (non 308 specific) Buffer and spring have to work together but are independent of other parts Just trying to make sure what I think is correct actually is.

I'm in Kaufman county

So carriers interchangeable, only bolts different from ar10 ro LR308? SO any carrier and any matched pair of AR10 bolt and barrel or LR308 bolt and barrel?

I missed the radius call out on the drawing, I had to look at the file on a web viewer since i'm at work. Still have one question/concern: I understand that a DPMS pattern upper with work with both LR308 and AR10 barrels and bolt groups as long as both barrel and bolt group match. do either the LR308 or AR10 bolt carriers cause any fitment issues with these dimensions?

I do have that, thanks. I've done several ar-15's and a Glock mag 9mm ar lower. This will be the first 308. I'm sure you know, there is lots of info, and it generally all agrees on dimensions for the smaller ar15 platforms. When I started looking for 308, wow. Not only does it vary from lr08 to ar10, but even within the same platform I have found dimensions vary as much as .075".

Perfect, thanks.

Thanks. I am assuming that the final pass in the FC pocket off centerline is with a 3/8" bit?

No offense, but I'm not buying a jig. That's like telling someone to put training wheels on a race car. Jigs work fine no question. But a mill with digital read outs is more accurate and does better work in most cases. Using a jig in a mill is actually harder because I would have to be careful not to damage the jig. My end mills have 2" length of cut, which would cut into the jig itself very easily.

Well, I really don't want to. I have a quality machine shop at the house including a pretty nice lathe and milling machine. If I bought a jig, I'd have to buy a router and that seems like a step backwards.

New here, and I'm looking at building a DPMS pattern rifle from an 80% receiver. I am trying to find a drawing for milling out the FCG and drilling the pins. I've seen a couple but the dimensions vary even though both are supposed to be for DPMS pattern. Anyone have a known good drawing?

Hello to all. I found this forum while searching for drawings for a receiver. I'm Scott, working as a Fire Investigator. I've been into building my own things for years, from guns and knives to suppressors, all the way to houses. I've been a shooter and hunter all my life. What brought me here was my latest project, building a 308 AR from an 80% receiver. I've got a small shop at the house where I do woodworking and metalworking. I have a lathe and a mill, and just got my latest toy in, a 50watt fiber laser engraver. I'm not new to building guns. I"ve built a few custom Mausers for my sons, put together a couple AR15's from parts, and have even completed a couple 80% AR15 receivers. It appears that this forum is the go to place for all things 308AR. I look forward to being here.
