    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.
