I bought this BCG previously and I had to take it to be staked at a local gunsmith. Are the BCGs visually inspected for light staking before shipping?
Skips on May 7, 2018
BEST ANSWER: Its hilarious how much importance dudes give to the quality of the staking for various bcg's. They don't own a caliper or mic but suddenly become QC experts...its the one thing they feel qualified to evaluate so it becomes everything...
Is the bolt Chrome plated and is the internal side of the carrier plated Chrome plated????
Is it high pressure tested??
What material is the firing pin made from??
Ronnie G on Apr 12, 2018
BEST ANSWER: Not chrome! Nickel. And they are the only way to go. I use several in long range 800 yd ARs and they never fail. Always keep clean and lubricated and they will last longer than you will!

Is this NiB BCG "M16 cut & full auto rated"?
Larry M on Apr 12, 2018
BEST ANSWER: It is a full auto profile. That's all PSA sells.
Is this HPT?
WWIII on Apr 12, 2018
BEST ANSWER: .........Palmetto: "pretty sure they are HPT" is not a good answer. You can verify if it is HPT or not....."pretty sure" doesn't cut it....
Is this BCG full auto rated?
Larry M on Apr 12, 2018
BEST ANSWER: Yes the carrier is milled as a M16 style so it will work on full auto if you have proper tax stamps and auto FCG.
When do you anticipate these be back in stock?
Tank T on May 29, 2018
BEST ANSWER: who cares?
Will the 556 bolt also work with the 300 bo?
Jayman on May 7, 2018

Does this have the PSA logo? Pics dont show one so i just want to confirm.
Chris N on Jun 16, 2018
BEST ANSWER: I purchased 4 NB BCGs. The NB BCGs I received did not have PSA logos.
Can the nib bcg be polished?
Jay K on Jul 6, 2018
BEST ANSWER: As delivered they are smooth as butter, and just about too shiny. So far they have been very easy to clean with no visible staining. We have run one over 1k rounds on a suppressed AR, still cleans up very well
What is the difference between this one and SKU 516445123?
Sean F on May 22, 2018
BEST ANSWER: i just looked at the the other sku numbers and compared them i really did not see a difference between the sku numbers there really the same bolt carrier. the only thing i can think of is there were ran on different dates or ran on different job numbers so there made them under different sku numbers for dates and/ or job numbers

Mike R on Sep 15, 2018
BEST ANSWER: only if you are using this BCG on a new upper build but if u are just replacing with another then you dont have to.
Maia ask what type of nickel boron coating You use and what is the difference between The psa nickel boron and the freedom nickel boron and premium nickel boron?????
Patrick T on May 31, 2018
BEST ANSWER: I believe that question is more for Palmetto State Armory to answer if I had an answer morning happy to tell youEnter an answer to this question.
Can this BCG be used in a .224 Valkyrie upper without any hitches? Thanks!
lonestar on May 9, 2018
BEST ANSWER: To answer your question no. The bolt itself needs to be for a 6.8 spc. so the bolt face wouldnt work. Everything else would function great if ur willing to switch bolts.

doug s on Sep 14, 2018
Smooth as butter

BEST ANSWER: I have purchased several of each from psa and the only difference I this one is it’s nickel boron coated, I’ve seen some say there MPI but I’ve seen no such marlings on the bcgs
Would this be a good upgrade for my stock SIG M400? (new guy)
Christopher W on Sep 1, 2018
BEST ANSWER: It would be a good upgrade for practically any AR15, including your Sig M400. These are great bcg. But I own a Sig M400 and it is good to go as-is. Your call.

This is the fourth BCG that I've order from the state, I'm extremely pleased with all of them and have had no problems what so ever. Plan on ordering more in the near future.

Beautifly machined BCG. !
Solid and was on sale for a great price. It became my active BCG and I retired the original as my backup. Top notch

Great buy, especially on sale with free shipping!
Bought it on sale to complete an upper I also bought from PSA. Bolt looks great, shot great too. No flaws I can think of.

Great BCG
Ordered one of these last time they were on sale. Bolt arrived in great packaging and ready to install. Bolt had a flaw in the cam channel that prevented it from operating correctly. PSA replaced without issue and the replacement BCG has worked flawlessly. Over 300+ rounds without a single failure. Will get another for my next build.Write your review here. It must be at least 20 characters long. Consider whether you would recommend this product and what you like or dislike about it.

To the folks just throwing these into old weapons
I really hope your checking headspace. No wonder some don't work right.
September 13, 2018
Don't need
The freedom series regular phosphate BCG and it has run flawlessly for hundreds and hundreds of rounds. It ain't as pretty as the nickel-boron, but both need to be cleaned and lubed occasionally. I wouldn't waste my money on the pretty one. There's no advantage to it.
September 13, 2018
Very slick bolt
Great bolt, better than the stock one. Accuracy and consistency greatly improved.
