    Makes sense … Can use the same mags and bolt as .308

  • ConLima

    And this is patterned for an Armalite and not a DPMS right?

    • Ergo

      not really. the pa10 ends up being a mish-mash of ar10 and dpms parts. Some of the small parts are armalite pattern. the barrel and bcg are dpms pattern. the receivers are close to dpms pattern but they have some idiosyncrasies that make it not 100% compatible.

      I have a pa10. In all honesty if you want a 7mm08 i wouldn’t recommend picking this up. Buy yourself a good barrel, decent bcg and all the other parts that go into an upper then send it off to someplace like adco for assembly.

      I have a pa10. It’s spent more time on a ups truck than the range. Palmetto made it right but it took a few trips from carolina to alabama before it ran 100%.

      • JSmath

        But it runs 100% now?

        • Ergo

          Yes it runs 100% but it took over 2 months and 3 trips on the ups truck to get it that way. That is a whole bucket of frustration i wouldn’t wish on anyone.
          If you just have to have the palmetto wait a few months. Don’t be a beta tester. Let some other schmuck make sure all the bugs are worked out.

            I believe the conventional wisdom at this point Is “if you buy pa10 upper, buy pa10 lower” since compatability Is not thoroughly understood. So mix and match pa upper, aim bcg, dpms lower, you might have problems. But get all psa parts and you’ll probably be fine.

          • Ergo

            compatibility is thoroughly understood. Palmetto made their own pattern rifle by using 4 armalite parts in the lpk. The barrel and bolt are dpms pattern. The receivers are supposed to be dpms low shelf. they aren’t but they are close enough to make a functional rifle by mixing and matching.

            It’s no different than trying to mix an armalite pattern with a rock river pattern or a dpms pattern. You have to buy parts that match the pattern.

    Love the 7mm-08. Originally made for 500 yd. Silueta Metallica.

  • jay

    that’s what the ar10 should have been.

  • HenryV

    I find these uppers in .308 alternatives to be very interesting. As others have said here the 7mm-08 is a good round. The .308 is getting some stiff competition in the big boy’s AR. They seem a bit more credible alternatives than some of the alternatives to the 5.56. Very interesting.

  • allan

    I have an Armalite 10A lower. Will this item fit Armalite lowers, or is it for DPMS specs?. Someone else asked, but I am not sure about the answer.

  • dave

    7mm-08 is a good caliber. I’m crossing my fingers that the price of creedmoor goes down and maybe palmetto can make us a good 6.5

    I too have dropped some “Coin” trying to determine worthiness of the PA-10. The DPMS Upper WILL fit the PTAC Lower. As for the PA-10 Uppers, the 2 that I purchased were the 16″ Stainless BBL with 15″ Midwest Rail and successfully mated to my Hellfire 80* Lowers once they were finished. Replaced stock DPMS Fire Control Group with a Geisselle SSA and a S.S. Fortis Mfg. Muzzle Brake. After working the “Bugs” out I can honestly say for the money invested these things sure shoot smooth and I have no regrets. Can’t say I’d ever do the 80* Lower thing again but am already on my 4th PA-10 Build. If you’re using any other Lower than the PA-10, PSA parts WONT work in them. DPMS Parts Kit worked fine in these “No-Name” 80* Lowers and should be fine with others compatible but Palmettos PA-10 Lowers should be completed with PSA Parts for propper fitting. PSA Chambers are ALL Tight, some more so than others so be aware. Polishing the Chamber helped resolve my problem but have heard that’s not always the case. No regrets from this “Bug Killing Schmuck”(Retired Toolmaker) and am Thankful PSA has made it affordable to get into the larger bore ARs. PSA Customer Service has always answered any questions I may have had and Yes their Q.C. continues to improve. Bottom line I wanted an AR-10 but for over 3k including the Optics couldn’t afford one. PSA has changed that considering I have less than $1000 in each of mine w/o optics and they both have surpassed all my expectations. No Regrets here.
