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!
WHEN will you have the nickel boron bcg back in stock?
Carlos B on Apr 21, 2018
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 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.
Will the 556 bolt also work with the 300 bo?
Jayman on May 7, 2018
BEST ANSWER: Well yes it will. The 300BO is a cut down and necked 556 case to accept a 308 projectile.
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.
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
When do you anticipate these be back in stock?
Tank T on May 29, 2018
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: No, you must use a 6.8 BCG for the .224 Valkyrie.
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 BCG and the BCG premium?
Ron L on Jun 8, 2018
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

Best deal ever
I used this bcg to complete a 22 Nosler last month. Just some minor adjustments of the gas block and shoots like a dream.

Great NB BCG.
Great bolt carrier group. Well made. Cleans easy. Nice smooth operation. Every bit as good as the ridiculously high priced BCG’s at an affordable price. I highly recommend this NB BCG. I now own 2 of them and run them in my last 2 builds.

Another Homerun
Bcg runs flawlessly currently using it for a 300 blackout would most definitely recommend to anyone looking for a upgrade Palmetto is always stealing the basses another run scored with price and product reliability fit and finish is always a head turner with this group of hard working folks amazing customer service and amazing quality control.

Best and most reliable BCG for the price!
You can easily pay more for much less value! I use this BCG on all of my builds.

An absolute steal @ $89.99
This is one heck of a product at an astounding price if you can catch the sale. I've one for my .300AAC and one in a 5.56 with roughly 700+ rounds through both and they are work horses that just don't quit. Grab 'em if you can they are slicker than snot and very well made.
