DPMS sold factory-built rifles, LOT'S of them - and they sold stripped receivers. Everything that came off the production line was serialized. Some went to the build line, others were determined to be sold as stripped receivers. Once the lowers were determined to be sold stripped, they went back to serialization and they stamped a K at the end of the serial number. That's how you know if you have a factory-built rifle, or something that someone built from stripped receivers. Your rifle appears to be a factory-built rifle. I won't say I know everything about the DPMS line, but I know alot about them. My first .308AR was a DPMS built from stripped receivers, and that was the 2009 timeframe. Back then, there wasn't much out there to build from. Believe it or not, that upper receiver is made from an extrusion, and the lower receiver is machined billet - there were very few ways to make them back then, and about the only receivers that were forged were the Armalite AR-10 receivers.

I certainly trust the source of this video and information.

I can't see your serial number close enough, but does it end with a "K"?...

That's legit, dude. I'm confirming it for you right now, as the real deal first Gen DPMS LR-308 receivers. In the old days, I could tell you when the lower receiver was made, to the month and year, but those databases are gone now.

^^^ Smartass...

Now, I'd risk that. Something I wanted to do as a kid, and tried a few times, just couldn't get it right. This is the only sling I'm good with...

2 days in a row!!! We got it Sunday and on Monday. Tore up a tree in my backyard on Sunday night. Crazy summer here, and monsoon season looks promising - supposed to be a good one this year, and so far it's doing a pretty good job.

Major internet personality. I always thought the guy was an idiot, from his beginning. This video proves something - I might not be incorrect in my original assumption of him. I can't believe that he went live, and looked this stupid, ON the Brownell's website. Seals the deal for me, accepting anything he ever has to say about anything. Ever. Joker is joker. Can't cut that bread any other way. Bullshiit artist, his whole time on the 'net.

Bro... It's NOT my weather that you're after... not right now... We're bangin' WELL above that right now, and dealing with that humidity, because Monsoon rain shiit... Our shiit this year is so random, it's not even funny. We blew out some 100+ in early March, then it calmed down a little. WeatherGuessers called it "back to Normal..." Whatever that means. Here's how random our July is, thus far. August will Suck as much, as well... I have no doubt... Random-Ass July...

LASSIE!!! Welcome aboard, man, literally. Nice work on the gun. Keep the Sprinco Orange, or run a Sprinco Red, and put the H3 back in it. The Red with the H3 in the longer extension is pretty much the Armalite AR-10 carbine spec from the factory - if only you could find the Armalite EA-1095 recoil spring. Doesn't matter, The Red is an identical performing spring. Orange works just fine, it's just made for the shorter AR15 carbine extension and the short 2.500" buffers. If it's running, let it run. I don't think any of the ammo you listed will give you any cycling issues...

LMMFAO!!!
