Palmetto AR pistol help - Page 2

stagpanther · January 3, 2018, 07:08 PM

My guess is most blow-back pistol caliber AR's have to have a firing pin spring in order to dampen the inertia resulting from the heavier bolt,buffer and buffer spring--but I'm not familiar with any modern DI AR's that use them.

This thread is about a 300 BO AR-15, so when Roughedge said he had the same problem, I figured it was on an AR-15. I see now that he has edited his post to clarify.

Did you take the bolt apart, inspect/clean and reassemble?

sure did, but it was after I contacted PSA. I was advised not to fire again after speaking with PSA. I received return label today, I'll keep everyone updated on the findings. Thanks again everyone

Hope you can get her running! My PSA 300 BLK Has been flawless and is my current truck gun! My other PSA products have been fine too! Did have a problem in PSA AR-10 but that was with aftermarket NB Bolt and went back to factory bolt and running fine after that!

If I had to bet the disconnector spring was put in upside down this will at times cause the disconnector to not "hook" the hammer as it should and let the hammer "ride" the bolt home and cause a second firing. The spring has a big end and a small end the big end goes down small end up. Common mistake when putting ARs together.

Hope its something that simple and a quick turn around! I can't wait to get it back and take to the range. From the few rounds I fired, I can tell it's going to be one of my favorites.

The AR platform is probably the easiest rifle to work on as a home/DIY gunsmith once you get familiar with it. I understand you being new to it not wanting to mess with it yourself, but just curious if you may have any friends that have built them or even a local gun shop probably could have had it fixed in 15 min without the hassle and wait of sending it back to PSA.

I'm hoping I'll be that "friend' eventually who builds ARs in the future. The LGS said it could be a few weeks until they could get to it and I'd have to pay. So back to PSA it was!

************UPDATE************
I hadn't heard anything from PSA for a couple weeks so I reached out and received this today . -

"The repairs department has sent this back out and they replaced the barrel, disconnect and spring.
Thank you for choosing Palmetto State Armory."

Curious to know if they would have even notified me of the repairs or shipping info had I not emailed them.. Oh well I'm excited to get it back, I'll let everyone know how she fires!

Thanks again TFL

Hmmm..now that's a riddle--trying to reverse guess-engineer what was actually wrong. They might not tell you--probably won't, but try asking them what was actually wrong. I'd sure like to know given the components that were changed. The hammer disconnector was a likely suspect--but the barrel--I'm wondering if there was an issue with the gas system that caused them to swap it out.

imashooter · January 22, 2018, 04:29 PM

Doubt if they would have notified you. Hope it's squared away. They're probably working with a skeleton crew with Shot Show 2018 going on. Believe it ends on the 26th and they'll all begin trickling back home.

Playing the Devil’s Advocate here....

Only several of you gave the OP the correct advice. Do not shoot the gun; contact PSA; and return the gun post haste.

I’m glad the OP did that; it was the only correct thing to do. All the other advice given - in my opinion should not have been given. Any of you remember the WI National Guard member who knowingly instructed an 18 year old student that the AR he loaned him to shoot could fire in full auto despite being a semi-auto gun? He went to prison for it; rightly so.

I disassembled a Colt 1908M .380 auto down to the bare frame. Upon reassembly I thought everything was put back together correctly but no, when I put a loaded magazine in the gun and chambered a round the gun tripled...without my finger on the trigger. I removed the slide and barrel and immediately sent the gun to a gunsmith to try to fix it. My fault - I re-installed the hammer incorrectly. Had I taken the gun to the range and said to my friends there “Hey Watch this” and chambered a round, repeating the full auto mode I would be breaking the law.

OK my point is - a brand new gun, firing more then one round with a single trigger pull is a machine gun even if there’s a defect causing the issue. The OP’s only course of action would be to return the gun to the manufacturer.

It was recently published that the Inspector General’s Office from the GAO tried unsuccessfully to illegally buy a firearm from some gun forum Members...nobody would sell them one! Moral of the story - big brother is among us online.....

I think you are misrepresenting this situation. The OP came on here seeking advice for something he did not understand-- a prime reason why this forum is such a great asset to the firearms community: that there are people on here willing to give freely of their advice to try to help frustrated people like that. If what you are really saying is that on-line advice is very hard to do with questionable quality of advice by people of questionable expertise and should be taken with a grain of salt--that's a fair statement, but there definitely some people on here that have knowledge and experience that I would say rises up to and beyond expert level (I freely admit I'm not one of them

). If only the world were a simple and perfect place where every firearm worked perfectly upon purchase--and it was a simple matter to return it to where you bought it when anything goes wrong. Probably wouldn't have any firearms forums if that were the case.

I was one of those that tried helping the OP, rather than scare the bejeezus out of him with talk of ending up in the slammer for life for illegally operating a home-made M60 machine gun. I was also the one the OP reached out to privately in messaging--and I advised to him to box it up and return it to PSA--which is what he did.

"Playing the common sense advocate"
I'll say anyone who doesn't perform the applicable "start up procedure" is borderline negligent.
"Loading a full magazine" in ANY semi-auto that has been dis-assembled(or is untested) is not a good start.

What? the majority of owner's manuals that I have usually advise complete familiarity of the weapon--and cleaning it--before operation.

No, most of the time that’s simply not true. If it fires on the trigger pull and trigger release, that’s not a machine gun. I had a trigger on a new Colt AR-15 break and do that sometimes. Now people are buying triggers that intentionally do that, and it’s expressly approved by the ATF.

But, by far, the most common cause I’ve seen of a rifle firing multiple shots is inadvertent bump-firing. I’ve worked at two ranges, and I’ve seen it many times. And no, it’s not illegal and no, it doesn’t make the rifle an illegal machine gun.

When a shooter with a rifle firing multiples hands it to an RSO and he can’t get it to duplicate the problem, and it doesn’t do it when disassembled and you're manually manipulating the hammer, that’s a dead giveaway that the culprit is simply bump-firing.

I’m not saying that bump-firing was the OP’s problem, I’m just saying that the vast majority of times this happens, there’s nothing illegal going on. Claiming it’s an illegal machine gun is pretty irresponsible without looking into the problem fully.
