Default New palmetto pa-10 problem

I just bought this new palmetto pa-10, I bought the lower (complete) on sale and then the upper (complete) separate, well I took it out shooting finally and the rifle was shooting way hard (recoil wise) and didnt want to feed.. so i packed up and came home and started looking over the rifle and I think I found the issue?

Picture kind of explains what I found.
Makes sense why it had so much recoil, the bcg was slamming into the lower and buffer tube and the buffer was doing nothing.. and feeding problem was prob because the wrong spring and buffer as well.

Everyone agree that this is my prob? Or is it supposed to work?

You should start by removing that CARBINE buffer, usually 3 to 3.5oz, and put in a RIFLE buffer at 5.2oz.

I have had one for several years now, works flawless, but overgassef as expected. The overgassing would make your lighter CARBINE buffer hit extremely hard.

Damage?
Many 308 AR clones are over gassed, giving the shooter more felt recoil than your typical 556,so...
Will it fire one round from the mag and lock the bcg back?
Is there damage to the receiver extension/buffer area being impacted by the carrier?

Yes that's a carbine buffer.

I also forgot to mention that the carbine length buffer tube from PSA for the PA-10 are NOT the same length as an actual AR-10 from Armalite. For carbines I believe the PSA tube uses the same length buffer as an AR-10. As far as a rifle buffer, you need to make sure it is shorter than the an AR-15 buffer because the BCG is longer.

Start from the beginning, where did you get the tube and buffer? Also, did you buy it for the AR-15 or AR-308? Then we will get you going from there.

Did the lower come with the stock, spring, buffer and tube? If it all came together from them, then someone there made a HUGE booboo!!!

This is what you need. I could not find it listed seperately, but look at the difference in the buffers.

I think you have two choices here. The obvious one is to contact them and have them send you the correct buffer and spring. Your other option would be to pull the steel weights out of that carbine buffer and add something heavier, like lead shot until you get to 5.2 or 5.4oz. That would require a scale though too.

yeah, that carbine buffer setup is incorrect for the rifle tube that's currently installed.

You have a Carbine buffer and spring in a rifle length tube and stock. Carbine buffers are a lot shorter and weight less. It’s not going to work like that unless you get a rifle length spring and buffer. Easy fix

OP are you telling a complete story? Because the last I read, PSA won't sell complete lowers to CA buyers. Only way possible was going through a 3rd party ffl like Audiophil.

doh!

don't feel bad though. problems with AR10s are pretty common, even when they don't sell or ship you something for a 22.
paying bucks up for a complete rifle from only a few companies seems the only way to avoid having to tinker a bit.

Especially without an adjustable gas block, yes.

I would shoot it with the new one they send you first and see if there are any feeding/ejection issues still (which I doubt) and go from there. Even if you do decide afterward to go with a heavier buffer, you can still shoot it with the current one until you get it without any problems.

I would also suggest buying 2 or 3 of these. You will already have a buffer, just remove the steel weights and put these in their place. Why spend twice as much only to have extra parts???
