98Z5V Posted August 30, 2015 Report Posted August 30, 2015 Tell your friend to start a complaint with PSA, list all his details and problems, and let them try to figure out where they went wrong. That's their factory gun. Please post details... lmaoThey'll have NO IDEA why it's fucking up...
CASEYPM Posted August 30, 2015 Author Report Posted August 30, 2015 I've filed a complaint and it has got me nowhere. I read somewhere that the mid length PA-10 is suppose to use an armalite 12-1/16 gas tube but doesn't because of copyrights by armalite. They can't even suggest you use one. It's not the barrel length, I used an Anderson dpms pattern with 9" gas port, it's the upper receiver that isn't proportionally correct for AR-15 gas tubes.
CASEYPM Posted August 30, 2015 Author Report Posted August 30, 2015 Question, does armalite threaded barrels use 5/8 x 24 tpi? While looking for that gas tube, I found a badass muzzle brake on sale for $20.
survivalshop Posted August 30, 2015 Report Posted August 30, 2015 Most 308 AR Barrels use 5/8x24 , you can probably order them differently .

CASEYPM Posted September 3, 2015 Author Report Posted September 3, 2015 (edited) Armalite12-1/16 "carbine length" fits perfectly. I wonder why they don't just put this in there to start with? The person that said it was because of copyrights is probably right. Now to try to find some range time this weekend! Edited September 3, 2015 by CASEYPM
CASEYPM Posted September 4, 2015 Author Report Posted September 4, 2015 (edited) Its finally done!!!! Thanks guys! Edited September 4, 2015 by CASEYPM
GreyGoose Posted September 4, 2015 Report Posted September 4, 2015 And... so did you hit the range... where's the report? ;-)CONGRATS!

CASEYPM Posted September 4, 2015 Author Report Posted September 4, 2015 And... so did you hit the range... where's the report? ;-)CONGRATS!Thanks. Not yet... I picked up a couple boxes of 7.62 NATO for $9.99 at wally world. But with the kids being out of school for holiday weekend and wife working all weekend, it just isn't happening. I have my eyes set on Tuesday when everyone is back at work and the range is empty. The only scope I have is a cheap no-name hand me down and not expecting much @ 100 yds. I may be pleasantly surprised.
392heminut Posted September 4, 2015 Report Posted September 4, 2015 Looks great! I'm looking forward to hearing how that Anderson barrel works for you, I've got one headed my way right now for a build.
CASEYPM Posted September 4, 2015 Author Report Posted September 4, 2015 Looks great! I'm looking forward to hearing how that Anderson barrel works for you, I've got one headed my way right now for a build.I'm hoping it's awesome! It'll be a definite win if the 5.56 priced .308 barrel performs well. I'll let you know.
CASEYPM Posted September 9, 2015 Author Report Posted September 9, 2015 Pretty badass! Although 8 out of 40 rounds failed to feed. 4 of which got stuck on the lugs and 4 times the bolt went into battery without a round in the barrel. I hosed it down with frog lube and ran great after that. This was at 30 yards with sighting in a cheapo truglo red dot. The last 3 rounds went through the same hole.
CASEYPM Posted September 9, 2015 Author Report Posted September 9, 2015 Looks great! I'm looking forward to hearing how that Anderson barrel works for you, I've got one headed my way right now for a build.Worked out pretty well. I think I'm going to have to get the dremel out and polish down the sharp edges on the lugs. I don't have a decent scope yet, so I didn't shoot past 30 yards.
blue109 Posted September 9, 2015 Report Posted September 9, 2015 Back away from the dremel......slowly....
CASEYPM Posted September 9, 2015 Author Report Posted September 9, 2015 (edited) Back away from the dremel......slowly....Perhaps I'm getting too eager? I've read of people using polishing compound on the lugs. Is this something that will work itself out with a higher round count? Also, there is brass shavings all over the bolt face and it looks to be from the ejector when the bolt rotates. They're round flecks. Looks like someone poured goldschlagger on the bolt. Here's the markings on the casings. Edited September 9, 2015 by CASEYPM
jtallen83 Posted September 9, 2015 Report Posted September 9, 2015 I get similar results on my P716 pistol with ZQI ammo but not in my AR-10 rifle. I'm thinking it is an overgassed issue with the bolt trying to open a bit too soon.....but that is just a guess. I'll be following along to see what the pros say..........

I'm thinking it is an overgassed issue with the bolt trying to open a bit too soon.....but that is just a guess. I'll be following along to see what the pros say..........I'm no pro either and I was kinda thinking that. I was a cheap ass and of course didn't spend the extra $20 for an adjustable gas block. I probably shouldn't of used ZQI NATO on its maiden voyage, but it came down to two boxes of that or only one of .308 Rem. I was reading a post on ar15.com similar to my problem and they told the guy "spray the bcg down with lube the way a woman uses hair spray". I thought I was running it wet, but after 20 rounds the piston rings were dry. So I did and it ran smoothly, but the ejector still shaved off some brass.
392heminut Posted September 10, 2015 Report Posted September 10, 2015 Casey, I think the gas tube issue is more due to the barrel than the upper receiver. I had the same issue as you with the gas tube being too short on the Matrix aerospace upper too.

I had the same issue as you with the gas tube being too short on the Matrix aerospace upper too.That may be the case. I just looked at the specs on mid length barrel. On my Anderson, where it tapers down for the gas block is 9" and the gas port is about 9.25". It guess it should be 8.75" and 9" They stated it was DPMS LR308 pattern, but with those measurements, it's a armalite AR-10 carbine length barrel. on the other hand, a gut that bought one from PSA already built had the same problem with the gas tube being too short and short cycling. This is my first black rifle and I'm just ecstatic that when I pull the bang switch, it goes bang. Edited September 10, 2015 by CASEYPM
