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

From their q&a

Think about this. Your scope tube is solid. You start changing the height of one ring and not the other you are putting the scope tube in a bind unless you lapp the rings. Then if you lapp them you can't adjust them again. On a 22 maybe but something to shoot distance you're not going to have the whole ring in contact with the scope tube

Welcome from KY. Nice rifles.

Luth is a small company that has been around for years. Their products are top shelf. I have not tried either of those stocks on my rifles. I have installed the Magpul 1 st gen PRS on several rifles for others. You should be well served by either. Green would match the rest of the rifle.

Guess I should actually read the box. 325 rnds not 333. Yes Federal Automatch. Just so surprised they had anything in the case at all. They don't even have shotshell.

Not being shipped but Walmart had 333rnd box's of the 22lr for $18.00 Only let me buy 3. So almost another thousand rnds of rimfire for $60 after tax. 6 cents a round is a bargin now.

Not sure I own ANYTHING that is Cal. Legal. I have 2 safes. Shopping for another at the moment.

I can't get mine to work w/my phone or Chromebook. Tried several different apps. Did get the LED's to light up but that's all. Some apps say my phone will work w/the camera some say no.

Yep it used to be free. Now they tell me I have to pay for enough space for all the photos I uploaded over the years.

Welcome from KY.

Both of my sig 308 pistol barrels are using a DPMS pattern bolt.

Butch's bore shine does a good job on copper.

You really should just build another gun and not mess up one that is already put together and working well. Belt-Fed can afford it.
