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.

Cuda55 created a new topic ' AR 10/DPMS Bolt CAD drawings need dim for cam pin and hole' in the forum. 2 months ago

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.

I have to ask "heavy enough" for what? It should be fine for use out to 600 yards but it becomes unstable around 800. If you want 1000 yard performance, go with the 175 grain SMK.

I've been using a Competition Electronics ProChono for about 10 years now and it's been fine. They just came out with bluetooth unit that plugs into it that allows me to get all my data onto my phone which I can then send to email or whatever. Kinda neat that it can speak out the velocity as it records it as well.

After 5 or 6 years, I finally planked some cash down for an AR10. Specifically a Windham R16SFST. It's the one with the 16.5" barrel and the keymod handguard.

wwpicR16SFST308.jpg

I HAD an LAR8, but it was a first generation one and it suuuuuucked. Actually, it shot MOA and had that great RRA two-stage trigger but it was a jam-o-matic with a lot of FTE sprinkled in. I also couldn't get FAL mags to work with it (though RRA at the time said they worked = lies) and RRA had no mags available.

Why am I back to the AR platform? Supression. I've got a SiCo Omega and it's fantastic on my bolt gun. However, it's a lot of screwing around with gas blocks and such to get my FAL to run supressed. At my age, I just want stuff to work without having to invent a solution, so it's an AR10 for me.

I'm looking forward to breaking the beastie in.

I wish I could upload a picture but my internet sucks. I would say it is a lowest grade rifle that would have gone for $5k or so brand new

What grade? This one makes it look like you robbed the place!
