Another issue pops up.
I'm very interested in a PA10 but I'm glad I waited on a purchase. Hopefully things will get settled soon. |

Thank you for your comments. The build kits were released within a few days of the lowers. We apologize for the delay.
The following items differ Between the AR15 and the PA10 lower receiver build kits: Front and rear take down pins (longer) The bolt catch (larger) The Mag catch The carbine buffer tube (longer) Carbine and rifle buffers (shorter) ---------------------------------------------------------------------------------------------------------------------------------------- I have approx. 80 rounds thru my PA-10, am not experiencing your anomaly. It came with a H1 AR15 buffer. The buffer spring is LONGER than AR15 Carbine spring but SHORTER than AR15 Rifle spring. The H1 buffer I have does not match PSA's reply above. "Carbine and rifle buffers (shorter)" The buffer tube is longer than AR15 carbine tube. Am having some minor issues locking fully loaded 20 & 25 rounds PMAGS with bolt closed. DPMS mags, even when empty require a hard rap against mag bottom to lock in place. Also minor scoring from the bolt carrier forward movement of the top round in the magazine, both PMAG and DPMS mags. When I have put nother 100 rounds thru it I'll evaluate and decide if I need to contact PSA for support. |

-------------------"Carbine and rifle buffers (shorter)"-------------
According to this PSA posting the AR15 H1, 3.25 inches length buffer that came with my lower assy is the wrong one. The DPMS 308 Carbine Buffers are 2.485 inches length (according to Midway USA Tech Info). Some day all the kinks will get worked out. |
|
Bought the complete .308 classic lower.
Checked the buffer and I have the 3.25 inch. |
|
|
I bought the .308 carbine buffer kit from Brownells. It seems to work perfect and it is the 3.25in buffer. I believe I will be investing in a Heavy buffer though
|
|
I will put the H2 buffer in the next range trip. Current H1 buffer is ejecting at the 1330 to 1400 clock position.
Hoping the H2 will get it closer to the 1500 clock position. I now have put approx. 80 rounds thru it. No major concerns. . Appears to be a serious difference between the PA-10 buffer in the LBK vs complete assembled lower assy. As per the Midway USA spec sheet: The DPMS LR-308 carbine buffer is approx .75 inches shorter than the AR15 carbine buffer and uses the standard AR15 carbine extension buffer tube. The LR- 308 carbine buffer spring is different than the AR-15 carbine buffer spring, Don't know how different. Don't believe I would shoot with the LBK short buffer without a confab with PSA tech services. |

I have sent an IM to PSA asking for input on the thread. Hopefully they'll take a look soon.

In my PA10 LBK I got from PSA 2 weeks ago, I got the shorter buffer.
My reading comp must be suffering because I cant tell from this thread whether it is supposed to be the "right" one. Quoted:
For reference: On the left is a standard H1 carbine buffer, on the right is the PA10 carbine buffer that came with the classic lower build kit. http://i1373.photobucket.com/albums/ag372/brendontripp/20141010_162120_zps228fe350.jpg View Quote |

View Quote In my rifle, the shorter buffer in the picture is the buffer that is too short for the PA10 6 position buffer tube that came in the classic lbk. With the shorter buffer was installed and the lower separated from the upper, I could push the bcg back in the buffer tube until the bcg hit the buffer tube. |

Bump for PSA to chime in. Looks as though the what is the correct buffer problem will be ignored in hopes it or the customers will go away they probably don't even know what is going on and they are trying to figure it out on the fly............ |

I picked up my 16" upper today.
Inside was the longer buffer. I did some loose fitting and the longer buffer keeps the BCG from hitting the buffer tube. So, now I am sitting here with two different buffers for the same rifle. Which is it and what to do? |

Thank you for the inquiry.
While the shorter buffer was initially used, we are currently using a standard carbine length heavy buffer for best performance with the wide variety of carriers available. If you purchased a PSA kit and received a short buffer, please IM us your order number and we will replace it. |

I received a UPS shipment notification from PSA yesterday for what I believe must be the replacement buffer. Quick work by PSA. Scheduled for delivery Monday. I'll confirm after it arrives.

Got my H buffer from PSA. It is the answer to the problem. It operates the action correctly as well.
|
|
The spring that came in my PA-10 complete lower assy with an H buffer is approx. 11.2 inches long, with 27 turns.
With H buffer installed shells were ejecting out to the 1-1:30 o'clock position. With an H2 buffer installed the shells are ejecting out to the 2:30-3 o'clock position. The spring in my PA-15 carbine is approx. 10 inches long, with 38 turns. |

Received my PA-10 build kit on Friday... my spring is roughly the same as M1911ptar's and my buffer is 3.25" long as well.

Quoted: The spring that came in my PA-10 complete lower assy with an H buffer is approx. 11.2 inches long, with 27 turns..... 27 coils? That is interesting. From the photo on the Aero website, their .308 buffer spring has ~38 coils, and the one on the DPMS website has 32-35 (hard to count a small photo). I wonder the lengths of these springs. |

View Quote Hking, The spring that came with my short buffer appears to me to be a standard AR15 carbine buffer, 10.5 inch, 39 coils. However, it did reject the cases to the 3-4 o'clock position. I'll asked my local Tennessean about the number of coils with the 12.5 inch spring that he said he had with the H buffer. That 12.5 inch almost sounds rifle length to me. Mark |

Well I just ordered (2) PSA PA10 .308 Complete Pistol Lower's and plan to build one I am glad I found this thread as I do not want any catastrophic failures happening on my clock. With the deal I got I could not pass it up and I am not planning on building pistols with it and will have (1) pistol buffer tube and buffer for trade if anyone wants to trade. I will be posting pics of the build as I get the funds to build it but I am looking at the Red X Arms barrels and really like this one http://shop.redxarms.com/308-STRAIGHT-FLUTED-20-HBAR-BARREL-30820HBARF.htm has anyone have any experience or knowledge on this barrel or barrel company?

tat2,
You will want to get another back plate and castle nut as well as the pistol does not come with a nut and the back plate does not have the notch that fits in the carbine buffer tube. I assume that you know, but I just wanted to give a little FYI that you will have a need for other parts than you listed. Quoted:

I thank you for the info on the parts needed for the buffer tube and Castle nut. I just wanted to know since this will be a rifle for long range and huntin g I will not need any type of Tactical butt stock or anything so I was wanting to know if my A2 butt stock off my bushy 20" 5.56 would work on it. I have several of the old A2 type butt stocks laying around.

tat2,
Just for the record, I do not work for PSA. I just live near enough to go to the store and have spent enough money there that I fund payroll!! LOL Putting the AR15 complete A2 stock on the lower may present a whole other issue. All the LBKs and complete lowers that PSA has sold has either been with a carbine length tube or the pistol tube. None have been sold with the A2 stock, and to be honest, there has been some confusion on buffers/springs being brought to light. You are getting into unfamiliar territory for me with the PA10 since I am very much a .308 AR newbie myself. You may want to steer the question about what you need for a rifle length buffer tube for the A2 stock to the AR Variants forum. There are a handful of very knowledgable folks there. Sounds like you will need a whole buffer/buffer tube/spring setup to run that stock. It may just be as simple as switching the stock between the guns, but IDK. Quoted:

Thanks Again lizARdman15,
I know I will have to buy the tube, Buffer & buffer spring I just wanted to know if the retro stock would work as this riffle will not be for CQB or tactical battle or anything this will be my hunting rifle and long range shooter so its not going to be built on that type of platform so that is why I asked as I don't see spending $250.00 on an adjustable stock with adjustable cheek weld and so on. I mean hey if I was going to dump another 200 bills into it I would surely use the $200 on a better optic and use the retro A2 butt stock. |

wow yea you got lucky not shooting more than 20.
as of today, still no replacement buffer. ETA.. I Post this and not 20 minutes later, they call me and say its ready for pickup. WAY TO GO PSA! :) |

From everything I see, they are using the correct spring. I might pick up a heavier spring anyways because I am having problems feeding the first 2 rounds from a full mag. Maybe the longer (maybe heavier) buffer PSA is sending out will help, who knows?
