I think with the Superformance ammo (powder, really), it's more about when the peak impulse happens, not how much. In the Superformance, it occurs later. It's maxing out later, just as the gas guns are trying to begin the ejection cycle. Bam, stuck case in the chamber.

Fire off your question in this sub-forum, and you'll get much, much better results: https://forum.308ar.com/forum/34-reloading/

Oly was always cool with their serial number information posted publicly. You could research most of their stuff, after the factory disaster. Prior to that, no info. DPMS doesn't have any of that, and people have been pushing them for it for years.

13xxx won't be a pre-ban receiver, according to the most common info on the 'net. It would have to be a receiver below serial number 10300. Here's a good example: http://209.251.48.101/forums/t_2_30/281582_DPMS-Early-Years.html

Sorry to see one go, anytime. REALLY don't like to see one go this way, though.

A .308AR with collapsible stock should be running the H3 equivalent - or, if it's genuine Armalite components, the actual H3 buffer.

Tell her it's parts for a Viper...

Better do some research on "Delta Team Tactical" before you buy anything from them. I'll give you a head start... http://theunapologeticindependent.blogspot.com/p/reviews.html https://www.northwestfirearms.com/threads/anyone-shop-at-deltateamtactical-com.219824/ This one is my favorite... http://www.pirate4x4.com/forum/outdoor-sports-recreation/2309018-delta-team-tactical-good-company-sucktacular.html http://www.ar15.com/forums/t_3_12/688195_What_a_joke_Delta_Team_Tactical_is.html http://www.northeastshooters.com/vbulletin/threads/303051-Another-Crappy-Vendor-Delta-Team-Tactical-(A-K-A-)-Omega-Manufacturing Just for good measure, here's their BBB report card... https://www.bbb.org/utah/business-reviews/advertising-agencies-and-counselors/delta-team-marketing-inc-in-vineyard-ut-22290621

Change ammo and retest your rifle configuration, as is, before you do anything else. Read here about Superformance and gas guns: http://www.hornady.com/ammunition/superformance-in-gas-operated-firearms "Due to the longer duration of peak pressure produced by Superformance™, the post peak/declining port pressure at common carbine and mid-length gas port locations is still higher than that produced by standard propellant. This has a tendency to flood the system with a larger volume of gas, at a higher velocity, that tries to open the bolt of the gun too fast. It’s a timing issue. The cartridge case is still swollen from the application of pressure during firing while the gun is simultaneously trying to extract the cartridge case before it has had an opportunity to settle back to its original size, or more simply: the gun is still in the process or firing while it’s trying to extract the cartridge case."

I'll be damned if that doesn't look JUST LIKE some corn-cob cleaning media. Like they didn't shake the cases out after polishing them - just dumped powder in there and went with it...

Pretty damned impressive! I like it!

Boyd's Tacticool stock, DIP bottom metal, painted it myself. LOTS you can do to these little things, and they're a HOOT!!!

Damn, that's a nice lookin' receiver set! Welcome aboard.

Awesome, brother!

You could break an anvil in a sandpit, brother...

I've had my GunTec for the longest time without fucking it up. I bought it back when that's about the only thing they made. Now, they make a shiit-ton of stuff. http://www.guntecusa.com/index.php?route=product/product&product_id=78 EDIT- for the record, I have a BUNCH of different armorer's wrenches. Some multi, some specific. My PRI barrel nut wrench is the most badass piece of kit in existence.

Matt, run your buffer length dimensional numbers from Slash's tech data, and use that for cutting your buffer down... http://heavybuffers.com/reference.html

I'm in with it. Let's launch 'em!!!

There are several A-Series complete uppers on Armalite's website, in stock. THey don't even list the stripped A-Series upper on their website right now. The best bet might be to just buy the entire upper. https://armalite.com/product-category/uppers/complete-halves/ar-10-complete-upper-half-assemblies/ These are in stock, as of this posting: https://armalite.com/shop/ar-10a-carbine-upper-assembly/ https://armalite.com/shop/ar-10a-supersass-carbine-upper-assembly/ https://armalite.com/shop/ar-10-b-series-16-tactical-complete-upper-half-assembly/

Larry, make sure you bring tickets with you to the Spring Shoot, brother!!!

Definitely staying out there Friday night. Might have to come back Saturday night to the house, unless we straight kidnap Matt and keep him longer... I'm in.

I take it you've seen this article? http://www.thetruthaboutguns.com/2011/06/foghorn/ask-foghorn-competition-iron-sights/ Also, check out Phoenix Precision (a manufacturer) and Fulton Armory (a vendor). Compass Lake Engineering, as well. They might have something that fills this need.

Replied to - Thanks, man!!!

I'm in, man - just let me know how to pay for them.

Hell yes.
