Yep Palmettos stuff only fits Palmettos stuff without a LOT of work.

Looks good. Glad you got it running.

I haven't had any problems w/my ASC Grendel mags in the 6ARC. I have only shot about 100 rounds so far. I bought some ASC's in FDE for the ARC so I can tell them apart from the loaded Grendel mags.

Welcome from KY.

The orange will probably work w/slash's buffer. I'd try that first. The Armalite spring is designed for a slightly longer buffer tube.

What I read on the link you posted for the upper is that it is their gen2 NOT DPMS G2. And I would also bet money the upper doesn't fit PSA's lowers. Like 98Z said just change the barrel to a standard DPMS pattern and you have lots of options. You are going to spend a ton of money and time chasing down compatable parts. These large frame guns are not built to any type of milspec standard.

Looks like the ground anchor for guy wires for a telephone pole.

We need a LOT more info to be able to help you. Search the thread "waterboarding" That's the kind of info we need to be able to help.

If there is a cap on the grip look inside the grip. That's usually where the put them.

Any of the DPMS style bcg's should work. I have 2 guns built on PA10 receiver sets. 1 has a PSA BCG the other I am using one from Brownells (their brand). Stop by the intro section and introduce yourself when you get a chance.

Get the cataract done. It's like new eyes. My right eye before surgery the big E at the top of the chart was a blur. Now 20/20 in that eye for distance. Still need readers for up close. If you scope is focused properly to your eyes you can take the glasses off.

I've never owned one but I had a customer at the gun shop and that's all he would buy. Swore by them. I also was a fan of Nikon.

The low mass bolt carrier now weighs less. You ordered a recoil system for the heavier BCG. It all works as a unit. You change something it effects everything else.

I think the pin the jig comes with to hold the 80% lower in the jig has a ball detent on the end to make it stay in place .

The long range targets need 75 gr projectiles for 5.56 https://www.theamericanmarksman.com/bullets-1st-7.62-m118lr-175-gr-125-ct.html These are priced decent for long range ammo. The shoot well in my guns.

The more F's the finer the grind on the powder. I'm betting if you use your powder measure then weigh the charges the 4F would which more. The larger grind would have more air spaces.

That looks like a bear creek upper. They should have head spaced it before it left the factory.

My Grendels run the steel cased ammo just fine. Not quite as accurate as the Hornady American Gunner or Black. Sure does a job on snapping turtles though.

That one should work w/the proper spring.

The KAK buffer in the 5 1/2 oz range w/the springco orange spring will probably work in your buffer tube. The Armalite set up is just a bit longer on length. That's why the buffer is a bit longer. Doesn't matter which stock set up you run as long as the the springs and buffer weights are correct to offset the BCG mass and amount of gas pushing the BCG rearward.

This should fix your problem. If the web shows out of stock call them. https://www.armalite.com/SACItem.aspx?Item=AR10REKIT01&ReturnURL=/Armalite/Product-Category/AR10-Parts-Accessories/Lower-Receiver-Parts&Category=ac614400-ff09-4cdf-9d35-419a654e7201
