Sorry it's taken so long. PG

Well, I finally mounted my optic and took the rifle to a 50 yard indoor range near my home. After three groups of 3 to achieve 100-yard zero, I shot two 3-round groups of two different ammo types. Pink are the more expensive Hornaday Deer and the green is cheap Remington. The two single shots were my standing and holding over the dot at 50 yards, trying for the bullseye. I'm not trained for rifle shooting, no prior service, so still am learning.

The spring and buffer arrived from Primary Arms today. Here's a quick photo before I button it up. Maybe range time after Thanksgiving travels. Thanks, fellows.

Thank you, Sir.

Thank you. I'll locate those items and install them this Fall. I'll be glad to avoid future reliability problems. I only have a very few rounds fired for this rifle, so don't know what I don't know...

I weighed the buffer and measured the internal depth this morning. The buffer weighs 3.8 oz, and the internal depth measures 6.996 in. The spring has 27-28 coils.

I bought the adjustable stock lower. Looking at the gas tube today, it falls short of reaching the mid-point of the semi-circular milled cut-out on the upper receiver. Maybe at the 40% point?

Hello everyone. First time poster here. I have enjoyed reading the discussion forums here for about 6 months now. Since I haven't seen much discussion about the PA-10 Gen 3, I though that I'd respond to this thread. I bought a Gen 3 PA-10 as a separate lower and upper this Summer (2020). So this production run incorporates whatever fixes PSA has accepted from the prior generation feedback. The upper is the 20" stainless, with a floating M-Lok handguard, and NiB bolt carrier group. The lower is pretty standard, with the EPT. I normally don't shoot .308 at our local indoor ranges, so have only fired it the one session to zero the flip-up iron sights. I guess that I fired only five 3-shot groups, because I had only visually boresighted the barrel to the iron sights at 25 yards at home. I had cleaned and heavily lubricated the rifle before taking it to the range, and had manually worked the action about 100 times or so. I was using new PMAG 10-round magazines. In summary, it ran without incident for all rounds fired, which were plain 150 grain Federal. I shot one group at 10 yards (single cartridge, then two cartridges in the magazine), adjusted the rear sight one click, and then repeated the three-shot group. Then moving the target to 25 yards, I repeated the process twice, but with three rounds loaded into the magazine. I adjusted the rear one more time, and then moved the target out to 50 yards, the limit at my range. I fired one three-round group and called it good enough. Using the iron sights, I managed ~1.25" (supported) at 50 yards, so I'm encouraged. The brass ejection was ~3 o'clock, neither forward or backward. Next I'll mount a small scope and find somewhere to shoot at 100 yards. But, so far, so good. I thought that folks on this discussion board would want to know.
