[ARCHIVED THREAD] - AA system ran good yesterday.

Posted: 3/16/2017 7:10:10 AM EDT

I bought an XLP last summer and it woud not fully cycle the next round. I sent it in to AA over Christmas and they drilled the has port on the barrel a little bigger and changed the gas block. So ehen I got it back and looked at it the gas block had no selector switch for adjustment. I looked at yhe website and didn't see this block for sale so I called AA. They said it was a new product that would work with pretty much any round with no need for adjustment(with the exception of possibly some subsonic unsuppressed). Well I finally went shooting yesterday and it ran flawlessly. About 200 rounds and no problems cycling what so ever.

.300 Blackout 10.5"

Cool, you got an upgrade for free.

300 blackout is a bit tricky to get to run for a GP setup.

Interesting, can you post a pic of the new gas block? I'm frustrated with my AA XLP built upper. It's not reliable with the 300 subs (with can attached).
The XLP 5 position gas black is somewhat of a joke as well since you really can't switch the gas settings without scratching the switch and or barrel/rail.
I sent my whole SBR in to AA last year for them to test. Course it ran like a champ in their shop.
Short of drilling out the gas block on the 300 bo barrel I may just convert it to a 556. My buddy has one of them which runs smooth.

Interested in seeing this new gas block as well. I have the old railed block with three positions, curious to see what they've done.

I'll take a pic when I get home, it's basically an XLP with no switch. I couldn't reach the switch under my handguard anyways.

Is there any other way to post pics other than photobucket? I can rarely get it to work. Here's the best I could do.

Don't need photo bucket anymore. Click reply to this post and then look down. You will see a "banner" that says "Click Here to Attach an Image from your Media Library to this Post".

Sorry, I don't see that anywhere. Maybe if you screenshot it and show me.

Only paid members have access to that feature.

That's why I can't see it.
