Hello all,
I recently purchased one of the PSA Gen 3 20" 308 PA10 uppers. It's been hard to source a actual PSA PA-10 lower since they're always OOS. At least from the last several weeks, almost a month now. 😒 I think i've done my research and figured I'd check here. Noreen claims after speaking with them, their 308 lowers are just DPMS GEN-1 pattern like PSA. It seems they do fit after reading about it on AR15.com The only unanswered question I found on this form is a post claiming the older Gen 2 suffered from the BCG crashing into the buffer. Some thought it was perhaps a bad extension or the lower buffer retaining pin needed to be cleared out more? Maybe its better to stick to PSA lowers? Here is the PA10 lower vs the Noreen. Let me know what you guys think?
